Class EJBProvider
java.lang.Objectorg.apache.axis.handlers.BasicHandler
- All Implemented Interfaces:
- org.apache.axis.Handler, Serializable
- public class EJBProvider
- extends org.apache.axis.providers.java.EJBProvider
A JBoss-compatible EJB Provider that exposes the methods of any session bean as a web service endpoint.
Basically it is a slimmed downed derivative of the Axis-EJBProvider without the usual, corba-related configuration mumbo-jumbo that is operating under the presumption that the right classloader has already been set by the request flow chain (@see org.jboss.net.axis.SetClassLoaderHandler).
Since Version 1.5 and thanks to Kevin Conner, we now also support
stateful beans that are tied to the service scope (you should reasonably
choose scope="session" in the
EJBProvider is able to recognize an WsdlAwareHttpActionHandler in its
transport chain such that it will set the soap-action headers in the wsdl.

| Field Detail |
remoteClass
protected Class remoteClass
- the real remote class we are shielding
ejbHome
protected Object ejbHome
- we are caching the home for perfomance purposes
ejbCreateMethod
protected Method ejbCreateMethod
- we are caching the create method for perfomance purposes
| Constructor Detail |
EJBProvider
public EJBProvider()
- Creates new EJBProvider
| Method Detail |
getEJBHome
protected Object getEJBHome(String jndiName) throws NamingException
- access home factory via jndi if
reference is not yet cached
- Throws:
NamingException
getEJBCreateMethod
protected Method getEJBCreateMethod(String jndiName) throws NamingException, NoSuchMethodException
- access home factory via jndi if
reference is not yet cached
- Throws:
NamingExceptionNoSuchMethodException
makeNewServiceObject
protected Object makeNewServiceObject(org.apache.axis.MessageContext msgContext, String clsName) throws Exception
- Return the object which implements the service lifecycle. Makes the usual
lookup->create call w/o the PortableRemoteDaDaDa for the sake of Corba.
- Parameters:
msgContext- the message contextclsName- The JNDI name of the EJB home class- Returns:
- an object that implements the service
- Throws:
Exception
getServiceClass
protected Class getServiceClass(String beanJndiName, org.apache.axis.handlers.soap.SOAPService service, org.apache.axis.MessageContext msgContext) throws org.apache.axis.AxisFault
- Return the class name of the service, note that this could be called
outside the correct chain, e.g., by the url mapper. Hence we need
to find the right classloader.
- Throws:
org.apache.axis.AxisFault
generateWSDL
public void generateWSDL(org.apache.axis.MessageContext msgContext)
throws org.apache.axis.AxisFault
- Generate the WSDL for this service.
We need to rearrange the classloader stuff for that purpose similar
as we did with the service class interface
- Throws:
org.apache.axis.AxisFault
processMessage
public void processMessage(org.apache.axis.MessageContext msgContext,
org.apache.axis.message.SOAPEnvelopeAxisImpl reqEnv,
org.apache.axis.message.SOAPEnvelopeAxisImpl resEnv,
Object obj)
throws Exception
- Override processMessage of super class in order
to unpack the service object from the lifecycle
- Throws:
Exception
initServiceDesc
public void initServiceDesc(org.apache.axis.handlers.soap.SOAPService service,
org.apache.axis.MessageContext msgContext)
throws org.apache.axis.AxisFault
- Throws:
org.apache.axis.AxisFault
