java.lang.Object org.springframework.orm.jdo.PersistenceManagerFactoryUtils
public abstract class PersistenceManagerFactoryUtils
Helper class featuring methods for JDO PersistenceManager handling, allowing for reuse of PersistenceManager instances within transactions. Also provides support for exception translation.
Used by JdoTemplate, JdoInterceptor, and JdoTransactionManager. Can also be used directly in application code, e.g. in combination with JdoInterceptor.

pmf
- PersistenceManagerFactory to create the PersistenceManager withallowCreate
- if a non-transactional PersistenceManager should be created
when no transactional PersistenceManager can be found for the current thread
DataAccessResourceFailureException
- if the PersistenceManager couldn't be obtained
IllegalStateException
- if no thread-bound PersistenceManager found and
"allowCreate" is false
JdoTransactionManager
public static javax.jdo.PersistenceManager doGetPersistenceManager(javax.jdo.PersistenceManagerFactory pmf, boolean allowCreate) throws javax.jdo.JDOException, IllegalStateException
true
.
Same as getPersistenceManager
, but throwing the original JDOException.

The most important cases like object not found or optimistic locking failure are covered here. For more fine-granular conversion, JdoAccessor and JdoTransactionManager support sophisticated translation of exceptions via a JdoDialect.
