java.lang.NoSuchMethodException: org.omg.stub.javax.ejb._EJBHome_Stub.create()
 Technote (troubleshooting)
 
Problem(Abstract)
An application running in WebSphere® Application Server V5 or V6 may receive the following exception when it calls create on an EJB home interface object:

java.lang.NoSuchMethodException: org.omg.stub.javax.ejb._EJBHome_Stub.create()
at java.lang.Class.getMethod(Class.java:1078)
...
 
Cause
The problem typically occurs when an EJB client application does a JNDI lookup of an EJB home interface but does not perform a narrow operation. The javax.ejb.EJBHome class does not define a create() method, and as a result, the NoSuchMethodException occurs. The EJB 2.0 and 2.1 specifications require (in section 6.10) that a narrow be performed after the JNDI lookup of an EJB home interface, before create() is called.
 
Resolving the problem
An example of how the EJB client code should perform the narrow is as follows:
Object home = initialContext.lookup(beanName);
EJBHome ejbHome = (EJBHome) PortableRemoteObject.narrow ((org.omg.CORBA.Object) home, EJBHome.class);

In this example, EJBHome is the name of the EJB home interface.

After changing the EJB client application code to perform the narrow, the NoSuchMethodException will no longer occur when calling create on the EJB home interface.
