Class JtaTransactionManager

java.lang.Object
  org.springframework.transaction.support.AbstractPlatformTransactionManager
      org.springframework.transaction.jta.JtaTransactionManager

All Implemented Interfaces:: Serializable, InitializingBean, TransactionFactory, PlatformTransactionManager

Direct Known Subclasses:: OC4JJtaTransactionManager, WebLogicJtaTransactionManager, WebSphereUowTransactionManager

public class JtaTransactionManager
extends AbstractPlatformTransactionManager
implements TransactionFactory, InitializingBean, Serializable
extends AbstractPlatformTransactionManager
implements TransactionFactory, InitializingBean, Serializable

PlatformTransactionManager implementation for JTA, delegating to a backend JTA provider. This is typically used to delegate to a J2EE server's transaction coordinator, but may also be configured with a local JTA provider which is embedded within the application.

This transaction manager is appropriate for handling distributed transactions, i.e. transactions that span multiple resources, and for controlling transactions on application server resources (e.g. JDBC DataSources available in JNDI) in general. For a single JDBC DataSource, DataSourceTransactionManager is perfectly sufficient, and for accessing a single resource with Hibernate (including transactional cache), HibernateTransactionManager is appropriate, for example.

Transaction synchronization is active by default, to allow data access support classes to register resources that are opened within the transaction for closing at transaction completion time. Spring's support classes for JDBC, Hibernate, JDO etc all perform such registration, allowing for reuse of the same Hibernate Session etc within the transaction. Standard JTA does not even guarantee that for Connections from a transactional JDBC DataSource: Spring's synchronization solves those issues.

For typical JTA transactions (REQUIRED, SUPPORTS, MANDATORY, NEVER), a plain JtaTransactionManager definition is all you need, completely portable across all J2EE servers. This corresponds to the functionality of the JTA UserTransaction, for which J2EE specifies a standard JNDI name ("java:comp/UserTransaction"). There is no need to configure a server-specific TransactionManager lookup for this kind of JTA usage.

Note: Advanced JTA usage below. Dealing with these mechanisms is not necessary for typical usage scenarios.

Transaction suspension (REQUIRES_NEW, NOT_SUPPORTED) is just available with a JTA TransactionManager being registered, via the "transactionManagerName" or "transactionManager" property. The location of this well-defined JTA object is not specified by J2EE; it is specific to each J2EE server, often kept in JNDI like the JTA UserTransaction. Some well-known JNDI locations are:

"java:comp/UserTransaction" for Resin 2.x, Oracle OC4J (Orion), JOnAS (JOTM), BEA WebLogic
"java:comp/TransactionManager" for Resin 3.x
"java:pm/TransactionManager" for Borland Enterprise Server and Sun Application Server (Sun ONE 7 and later)
"java:/TransactionManager" for JBoss Application Server

All of these cases are autodetected by JtaTransactionManager (since Spring 1.2), provided that the "autodetectTransactionManager" flag is set to "true" (which it is by default). Consequently, JtaTransactionManager will support transaction suspension out-of-the-box on many J2EE servers.

Note: Support for the JTA TransactionManager interface is not required by J2EE. Almost all J2EE servers expose it, but do so as extension to J2EE. There might be some issues with compatibility, despite the TransactionManager interface being part of JTA. As a consequence, Spring provides various vendor-specific PlatformTransactionManagers, which are recommended to be used if appropriate: WebLogicJtaTransactionManager, WebSphereUowTransactionManager and OC4JJtaTransactionManager. For all other J2EE servers, the standard JtaTransactionManager is sufficient.

This pure JtaTransactionManager supports timeouts but not per-transaction isolation levels. Custom subclasses may override doJtaBegin(org.springframework.transaction.jta.JtaTransactionObject, org.springframework.transaction.TransactionDefinition) for specific JTA extensions in order to provide this functionality; Spring includes corresponding WebLogicJtaTransactionManager and OC4JJtaTransactionManager classes, for BEA's WebLogic Server and Oracle's OC4J, respectively. Such adapters for specific J2EE transaction coordinators may also expose transaction names for monitoring; with standard JTA, transaction names will simply be ignored.

JTA 1.1 adds the TransactionSynchronizationRegistry facility, as public Java EE 5 API in addition to the standard JTA UserTransaction handle. As of Spring 2.1, this JtaTransactionManager autodetects the TransactionSynchronizationRegistry and uses it for registering Spring-managed synchronizations when participating in an existing JTA transaction (e.g. controlled by EJB CMT). If no TransactionSynchronizationRegistry is available (or the JTA 1.1 API isn't available), then such synchronizations will be registered via the (non-J2EE) JTA TransactionManager handle.

This class is serializable. However, active synchronizations do not survive serialization.

JtaTransactionManager

public JtaTransactionManager(UserTransaction userTransaction)

Create a new JtaTransactionManager instance.

Parameters:: userTransaction - the JTA UserTransaction to use as direct reference

JtaTransactionManager

public JtaTransactionManager(UserTransaction userTransaction,
                             TransactionManager transactionManager)

Create a new JtaTransactionManager instance.

Parameters:: userTransaction - the JTA UserTransaction to use as direct reference; transactionManager - the JTA TransactionManager to use as direct reference

JtaTransactionManager

public JtaTransactionManager(TransactionManager transactionManager)

Create a new JtaTransactionManager instance.

Parameters:: transactionManager - the JTA TransactionManager to use as direct reference

Method Detail

setJndiTemplate

public void setJndiTemplate(JndiTemplate jndiTemplate)

Set the JndiTemplate to use for JNDI lookups. A default one is used if not set.

getJndiTemplate

public JndiTemplate getJndiTemplate()

Return the JndiTemplate used for JNDI lookups.

setJndiEnvironment

public void setJndiEnvironment(Properties jndiEnvironment)

Set the JNDI environment to use for JNDI lookups. Creates a JndiTemplate with the given environment settings.

See Also:: setJndiTemplate(org.springframework.jndi.JndiTemplate)

getJndiEnvironment

public Properties getJndiEnvironment()

Return the JNDI environment to use for JNDI lookups.

setUserTransaction

public void setUserTransaction(UserTransaction userTransaction)

Set the JTA UserTransaction to use as direct reference.

Typically just used for local JTA setups; in a J2EE environment, the UserTransaction will always be fetched from JNDI.

See Also:: setUserTransactionName(java.lang.String), setAutodetectUserTransaction(boolean)

getUserTransaction

public UserTransaction getUserTransaction()

Return the JTA UserTransaction that this transaction manager uses.

setUserTransactionName

public void setUserTransactionName(String userTransactionName)

Set the JNDI name of the JTA UserTransaction.

Note that the UserTransaction will be autodetected at the J2EE default location "java:comp/UserTransaction" if not specified explicitly.

See Also:: DEFAULT_USER_TRANSACTION_NAME, setUserTransaction(javax.transaction.UserTransaction), setAutodetectUserTransaction(boolean)

setAutodetectUserTransaction

public void setAutodetectUserTransaction(boolean autodetectUserTransaction)

Set whether to autodetect the JTA UserTransaction at its default JNDI location "java:comp/UserTransaction", as specified by J2EE. Will proceed without UserTransaction if none found.

Default is "true", autodetecting the UserTransaction unless it has been specified explicitly. Turn this flag off to allow for JtaTransactionManager operating against the TransactionManager only, despite a default UserTransaction being available.

See Also:: DEFAULT_USER_TRANSACTION_NAME

setCacheUserTransaction

public void setCacheUserTransaction(boolean cacheUserTransaction)

Set whether to cache the JTA UserTransaction object fetched from JNDI.

Default is "true": UserTransaction lookup will only happen at startup, reusing the same UserTransaction handle for all transactions of all threads. This is the most efficient choice for all application servers that provide a shared UserTransaction object (the typical case).

Turn this flag off to enforce a fresh lookup of the UserTransaction for every transaction. This is only necessary for application servers that return a new UserTransaction for every transaction, keeping state tied to the UserTransaction object itself rather than the current thread.

See Also:: setUserTransactionName(java.lang.String)

setTransactionManager

public void setTransactionManager(TransactionManager transactionManager)

Set the JTA TransactionManager to use as direct reference.

A TransactionManager is necessary for suspending and resuming transactions, as this not supported by the UserTransaction interface.

Note that the TransactionManager will be autodetected if the JTA UserTransaction object implements the JTA TransactionManager interface too, as well as autodetected at various well-known fallback JNDI locations.

See Also:: setTransactionManagerName(java.lang.String), setAutodetectTransactionManager(boolean)

getTransactionManager

public TransactionManager getTransactionManager()

Return the JTA TransactionManager that this transaction manager uses.

setTransactionManagerName

public void setTransactionManagerName(String transactionManagerName)

Set the JNDI name of the JTA TransactionManager.

A TransactionManager is necessary for suspending and resuming transactions, as this not supported by the UserTransaction interface.

See Also:: setTransactionManager(javax.transaction.TransactionManager), setAutodetectTransactionManager(boolean)

setAutodetectTransactionManager

public void setAutodetectTransactionManager(boolean autodetectTransactionManager)

Set whether to autodetect a JTA UserTransaction object that implements the JTA TransactionManager interface too (i.e. the JNDI location for the TransactionManager is "java:comp/UserTransaction", same as for the UserTransaction). Also checks the fallback JNDI locations "java:comp/TransactionManager" and "java:/TransactionManager". Will proceed without TransactionManager if none found.

Default is "true", autodetecting the TransactionManager unless it has been specified explicitly. Can be turned off to deliberately ignore an available TransactionManager, for example when there are known issues with suspend/resume and any attempt to use REQUIRES_NEW or NOT_SUPPORTED should fail fast.

See Also:: FALLBACK_TRANSACTION_MANAGER_NAMES

setTransactionSynchronizationRegistryName

public void setTransactionSynchronizationRegistryName(String transactionSynchronizationRegistryName)

Set the JNDI name of the JTA 1.1 TransactionSynchronizationRegistry.

Note that the TransactionSynchronizationRegistry will be autodetected at the Java EE 5 default location "java:comp/TransactionSynchronizationRegistry" if not specified explicitly.

See Also:: DEFAULT_TRANSACTION_SYNCHRONIZATION_REGISTRY_NAME

setAllowCustomIsolationLevels

public void setAllowCustomIsolationLevels(boolean allowCustomIsolationLevels)

Set whether to allow custom isolation levels to be specified.

Default is "false", throwing an exception if a non-default isolation level is specified for a transaction. Turn this flag on if affected resource adapters check the thread-bound transaction context and apply the specified isolation levels individually (e.g. through a IsolationLevelDataSourceRouter).

See Also:: IsolationLevelDataSourceRouter

Throws:: TransactionSystemException - in case of errors
See Also:: setUserTransaction(javax.transaction.UserTransaction), setUserTransactionName(java.lang.String)

retrieveTransactionManager

protected TransactionManager retrieveTransactionManager()
                                                 throws TransactionSystemException

Allows subclasses to retrieve the JTA TransactionManager in a vendor-specific manner. Only called if no "transactionManager" or "transactionManagerName" specified.

The default implementation simply returns null.

Returns:: the JTA TransactionManager handle to use, or null if none found
Throws:: TransactionSystemException - in case of errors
See Also:: setTransactionManager(javax.transaction.TransactionManager), setTransactionManagerName(java.lang.String)

retrieveTransactionSynchronizationRegistry

protected Object retrieveTransactionSynchronizationRegistry()
                                                     throws TransactionSystemException

Allows subclasses to retrieve the JTA 1.1 TransactionSynchronizationRegistry in a vendor-specific manner.

The default implementation simply returns null.

Returns:: the JTA TransactionSynchronizationRegistry handle to use, or null if none found
Throws:: TransactionSystemException - in case of errors

findUserTransaction

protected UserTransaction findUserTransaction()

Find the JTA UserTransaction through a default JNDI lookup: "java:comp/UserTransaction".

Returns:: the JTA UserTransaction reference, or null if not found
See Also:: DEFAULT_USER_TRANSACTION_NAME

findTransactionManager

protected TransactionManager findTransactionManager(UserTransaction ut)

Find the JTA TransactionManager through autodetection: checking whether the UserTransaction object implements the TransactionManager, and checking the fallback JNDI locations.

Parameters:: ut - the JTA UserTransaction object
Returns:: the JTA TransactionManager reference, or null if not found
See Also:: FALLBACK_TRANSACTION_MANAGER_NAMES

findTransactionSynchronizationRegistry

protected Object findTransactionSynchronizationRegistry(UserTransaction ut,
                                                        TransactionManager tm)
                                                 throws TransactionSystemException

Find the JTA 1.1 TransactionSynchronizationRegistry through autodetection: checking whether the UserTransaction object or TransactionManager object implements it, and checking Java EE 5's standard JNDI location.

The default implementation simply returns null.

Parameters:: ut - the JTA UserTransaction object; tm - the JTA TransactionManager object
Returns:: the JTA TransactionSynchronizationRegistry handle to use, or null if none found
Throws:: TransactionSystemException - in case of errors

doGetTransaction

protected Object doGetTransaction()

This implementation returns a JtaTransactionObject instance for the JTA UserTransaction.

The UserTransaction object will either be looked up freshly for the current transaction, or the cached one looked up at startup will be used. The latter is the default: Most application servers use a shared singleton UserTransaction that can be cached. Turn off the "cacheUserTransaction" flag to enforce a fresh lookup for every transaction.

Specified by:: doGetTransaction in class AbstractPlatformTransactionManager

Returns:: the current transaction object
See Also:: setCacheUserTransaction(boolean)

doGetJtaTransaction

protected JtaTransactionObject doGetJtaTransaction(UserTransaction ut)

Get a JTA transaction object for the given current UserTransaction.

Subclasses can override this to provide a JtaTransactionObject subclass, for example holding some additional JTA handle needed.

Parameters:: ut - the UserTransaction handle to use for the current transaction
Returns:: the JtaTransactionObject holding the UserTransaction

isExistingTransaction

protected boolean isExistingTransaction(Object transaction)

Description copied from class: AbstractPlatformTransactionManager

Check if the given transaction object indicates an existing transaction (that is, a transaction which has already started).

The result will be evaluated according to the specified propagation behavior for the new transaction. An existing transaction might get suspended (in case of PROPAGATION_REQUIRES_NEW), or the new transaction might participate in the existing one (in case of PROPAGATION_REQUIRED).

The default implementation returns false, assuming that participating in existing transactions is generally not supported. Subclasses are of course encouraged to provide such support.

Overrides:: isExistingTransaction in class AbstractPlatformTransactionManager

Parameters:: transaction - transaction object returned by doGetTransaction
Returns:: if there is an existing transaction
See Also:: AbstractPlatformTransactionManager.doGetTransaction()

useSavepointForNestedTransaction

protected boolean useSavepointForNestedTransaction()

This implementation returns false to cause a further invocation of doBegin despite an already existing transaction.

JTA implementations might support nested transactions via further UserTransaction.begin() invocations, but never support savepoints.

Overrides:: useSavepointForNestedTransaction in class AbstractPlatformTransactionManager

See Also:: doBegin(java.lang.Object, org.springframework.transaction.TransactionDefinition), UserTransaction.begin()

doBegin

protected void doBegin(Object transaction,
                       TransactionDefinition definition)

Description copied from class: AbstractPlatformTransactionManager

Begin a new transaction with semantics according to the given transaction definition. Does not have to care about applying the propagation behavior, as this has already been handled by this abstract manager.

This method gets called when the transaction manager has decided to actually start a new transaction. Either there wasn't any transaction before, or the previous transaction has been suspended.

A special scenario is a nested transaction without savepoint: If useSavepointForNestedTransaction() returns "false", this method will be called to start a nested transaction when necessary. In such a context, there will be an active transaction: The implementation of this method has to detect this and start an appropriate nested transaction.

Specified by:: doBegin in class AbstractPlatformTransactionManager

Parameters:: transaction - transaction object returned by doGetTransaction; definition - TransactionDefinition instance, describing propagation behavior, isolation level, read-only flag, timeout, and transaction name

doJtaBegin

protected void doJtaBegin(JtaTransactionObject txObject,
                          TransactionDefinition definition)
                   throws NotSupportedException,
                          SystemException

Perform a JTA begin on the JTA UserTransaction or TransactionManager.

This implementation only supports standard JTA functionality: that is, no per-transaction isolation levels and no transaction names. Can be overridden in subclasses, for specific JTA implementations.

Calls applyIsolationLevel and applyTimeout before invoking the UserTransaction's begin method.

Parameters:: txObject - the JtaTransactionObject containing the UserTransaction; definition - TransactionDefinition instance, describing propagation behavior, isolation level, read-only flag, timeout, and transaction name
Throws:: NotSupportedException - if thrown by JTA methods; SystemException - if thrown by JTA methods
See Also:: getUserTransaction(), getTransactionManager(), applyIsolationLevel(org.springframework.transaction.jta.JtaTransactionObject, int), applyTimeout(org.springframework.transaction.jta.JtaTransactionObject, int), JtaTransactionObject.getUserTransaction(), UserTransaction.setTransactionTimeout(int), UserTransaction.begin()

applyIsolationLevel

protected void applyIsolationLevel(JtaTransactionObject txObject,
                                   int isolationLevel)
                            throws InvalidIsolationLevelException,
                                   SystemException

Apply the given transaction isolation level. The default implementation will throw an exception for any level other than ISOLATION_DEFAULT.

To be overridden in subclasses for specific JTA implementations, as alternative to overriding the full doJtaBegin(org.springframework.transaction.jta.JtaTransactionObject, org.springframework.transaction.TransactionDefinition) method.

Parameters:: txObject - the JtaTransactionObject containing the UserTransaction; isolationLevel - isolation level taken from transaction definition
Throws:: InvalidIsolationLevelException - if the given isolation level cannot be applied; SystemException - if thrown by the JTA implementation
See Also:: doJtaBegin(org.springframework.transaction.jta.JtaTransactionObject, org.springframework.transaction.TransactionDefinition), JtaTransactionObject.getUserTransaction(), getTransactionManager()

applyTimeout

protected void applyTimeout(JtaTransactionObject txObject,
                            int timeout)
                     throws SystemException

Apply the given transaction timeout. The default implementation will call UserTransaction.setTransactionTimeout for a non-default timeout value.

Parameters:: txObject - the JtaTransactionObject containing the UserTransaction; timeout - timeout value taken from transaction definition
Throws:: SystemException - if thrown by the JTA implementation
See Also:: doJtaBegin(org.springframework.transaction.jta.JtaTransactionObject, org.springframework.transaction.TransactionDefinition), JtaTransactionObject.getUserTransaction(), UserTransaction.setTransactionTimeout(int)

doSuspend

protected Object doSuspend(Object transaction)

Description copied from class: AbstractPlatformTransactionManager

Suspend the resources of the current transaction. Transaction synchronization will already have been suspended.

The default implementation throws a TransactionSuspensionNotSupportedException, assuming that transaction suspension is generally not supported.

Overrides:: doSuspend in class AbstractPlatformTransactionManager

Parameters:: transaction - transaction object returned by doGetTransaction
Returns:: an object that holds suspended resources (will be kept unexamined for passing it into doResume)
See Also:: AbstractPlatformTransactionManager.doResume(java.lang.Object, java.lang.Object)

doJtaSuspend

protected Object doJtaSuspend(JtaTransactionObject txObject)
                       throws SystemException

Perform a JTA suspend on the JTA TransactionManager.

Can be overridden in subclasses, for specific JTA implementations.

Parameters:: txObject - the JtaTransactionObject containing the UserTransaction
Returns:: the suspended JTA Transaction object
Throws:: SystemException - if thrown by JTA methods
See Also:: getTransactionManager(), TransactionManager.suspend()

doResume

protected void doResume(Object transaction,
                        Object suspendedResources)

Description copied from class: AbstractPlatformTransactionManager

Resume the resources of the current transaction. Transaction synchronization will be resumed afterwards.

The default implementation throws a TransactionSuspensionNotSupportedException, assuming that transaction suspension is generally not supported.

Overrides:: doResume in class AbstractPlatformTransactionManager

Parameters:: transaction - transaction object returned by doGetTransaction; suspendedResources - the object that holds suspended resources, as returned by doSuspend
See Also:: AbstractPlatformTransactionManager.doSuspend(java.lang.Object)

doJtaResume

protected void doJtaResume(JtaTransactionObject txObject,
                           Object suspendedTransaction)
                    throws InvalidTransactionException,
                           SystemException

Perform a JTA resume on the JTA TransactionManager.

Can be overridden in subclasses, for specific JTA implementations.

Parameters:: txObject - the JtaTransactionObject containing the UserTransaction; suspendedTransaction - the suspended JTA Transaction object
Throws:: InvalidTransactionException - if thrown by JTA methods; SystemException - if thrown by JTA methods
See Also:: getTransactionManager(), TransactionManager.resume(javax.transaction.Transaction)

shouldCommitOnGlobalRollbackOnly

protected boolean shouldCommitOnGlobalRollbackOnly()

This implementation returns "true": a JTA commit will properly handle transactions that have been marked rollback-only at a global level.

Overrides:: shouldCommitOnGlobalRollbackOnly in class AbstractPlatformTransactionManager

See Also:: AbstractPlatformTransactionManager.doCommit(org.springframework.transaction.support.DefaultTransactionStatus), DefaultTransactionStatus.isGlobalRollbackOnly(), AbstractTransactionStatus.isLocalRollbackOnly(), TransactionStatus.setRollbackOnly(), UnexpectedRollbackException, UserTransaction.commit(), RollbackException

doCommit

protected void doCommit(DefaultTransactionStatus status)

Description copied from class: AbstractPlatformTransactionManager

Perform an actual commit of the given transaction.

An implementation does not need to check the "new transaction" flag or the rollback-only flag; this will already have been handled before. Usually, a straight commit will be performed on the transaction object contained in the passed-in status.

Specified by:: doCommit in class AbstractPlatformTransactionManager

Parameters:: status - the status representation of the transaction
See Also:: DefaultTransactionStatus.getTransaction()

doRollback

protected void doRollback(DefaultTransactionStatus status)

Description copied from class: AbstractPlatformTransactionManager

Perform an actual rollback of the given transaction.

An implementation does not need to check the "new transaction" flag; this will already have been handled before. Usually, a straight rollback will be performed on the transaction object contained in the passed-in status.

Specified by:: doRollback in class AbstractPlatformTransactionManager

Parameters:: status - the status representation of the transaction
See Also:: DefaultTransactionStatus.getTransaction()

doSetRollbackOnly

protected void doSetRollbackOnly(DefaultTransactionStatus status)

Description copied from class: AbstractPlatformTransactionManager

Set the given transaction rollback-only. Only called on rollback if the current transaction participates in an existing one.

The default implementation throws an IllegalTransactionStateException, assuming that participating in existing transactions is generally not supported. Subclasses are of course encouraged to provide such support.

Overrides:: doSetRollbackOnly in class AbstractPlatformTransactionManager

Parameters:: status - the status representation of the transaction

registerAfterCompletionWithExistingTransaction

protected void registerAfterCompletionWithExistingTransaction(Object transaction,
                                                              List synchronizations)

Description copied from class: AbstractPlatformTransactionManager

Invoked when the control of the Spring transaction manager and thus all Spring transaction synchronizations end, without the transaction being completed yet. This is for example the case when participating in an existing JTA or EJB CMT transaction.

The default implementation simply invokes the afterCompletion methods immediately, passing in "STATUS_UNKNOWN". This is the best we can do if there's no chance to determine the actual outcome of the outer transaction.

Overrides:: registerAfterCompletionWithExistingTransaction in class AbstractPlatformTransactionManager

Parameters:: transaction - transaction object returned by doGetTransaction; synchronizations - List of TransactionSynchronization objects
See Also:: AbstractPlatformTransactionManager.invokeAfterCompletion(java.util.List, int), TransactionSynchronization.afterCompletion(int), TransactionSynchronization.STATUS_UNKNOWN

doRegisterAfterCompletionWithJtaTransaction

protected void doRegisterAfterCompletionWithJtaTransaction(JtaTransactionObject txObject,
                                                           List synchronizations)
                                                    throws RollbackException,
                                                           SystemException

Register a JTA synchronization on the JTA TransactionManager, for calling afterCompletion on the given Spring TransactionSynchronizations.

The default implementation registers the synchronizations on the JTA 1.1 TransactionSynchronizationRegistry, if available, or on the JTA TransactionManager's current Transaction - again, if available. If none of the two is available, a warning will be logged.

Can be overridden in subclasses, for specific JTA implementations.

Parameters:: txObject - the current transaction object; synchronizations - List of TransactionSynchronization objects
Throws:: RollbackException - if thrown by JTA methods; SystemException - if thrown by JTA methods
See Also:: getTransactionManager(), Transaction.registerSynchronization(javax.transaction.Synchronization), TransactionSynchronizationRegistry.registerInterposedSynchronization(javax.transaction.Synchronization)

createTransaction

public Transaction createTransaction(String name,
                                     int timeout)
                              throws NotSupportedException,
                                     SystemException

Description copied from interface: TransactionFactory

Create an active Transaction object based on the given name and timeout.

Specified by:: createTransaction in interface TransactionFactory

Parameters:: name - the transaction name (may be null); timeout - the transaction timeout (may be -1 for the default timeout)
Returns:: the active Transaction object (never null)
Throws:: NotSupportedException - if the transaction manager does not support a transaction of the specified type; SystemException - if the transaction managed failed to create the transaction
