APAR status

• Closed as program error.

Error description

• The following error is caused when the ORB can't find an
  enterprise beans's stub(s):
  
  org.omg.CORBA.INV_OBJREF: Could not load stub for
  com.ibm.EJSRemoteStatelessMyBeanEJB_a412961d
  
  A org.omg.CORBA.INV_OBJREF exception can be caused for many
  reasons, the cause of the exception here is very
  specific and not easily or commonly hit.  This issue occurs
  when the ORB attempts to locate an EJB stub and it can not
  find the stub.  The stub can't be found by the current
  ClassLoader because those stub are not contained in the
  clients application.  Typically an EJB's stubs are packaged
  in an application when that application contains a client to
  the EJB.  However, in this case, the stubs are located in a
  separate application or jar.

  *                  Server V6.0.2 and V6.1.0.                   *

  * PROBLEM DESCRIPTION: EJB stubs are not found by current      *
  *                      ClassLoader, thus yielding a            *

  ****************************************************************
  The org.omg.CORBA.INV_OBJREF occurs when a remote EJB object
  has to be returned to a cross-application, collocated stub;
  where the remote object has to go unused long enough to be
  flushed from the EJB Container cache; and an application with
  missing stubs needs to call a method on the object. That is,
  the EJB stubs are not contained in the application making the
  request.
  

Problem conclusion

• The fix for this APAR will ensure the correct ClassLoader is
  on the thread when the ORB attempts to locate an EJB's stub.
  The code for this APAR is enabled by a JVM system property.
  To apply the system property, follow these steps:
  
  1. Open the administrative console.
  2. Select Servers.
  3. Select Application Servers.
  4. Select the server you want to configure.
  5. In the Server Infrastructure area, select Java and
  Process Management.
  6. In the Server Infrastructure area, select Process
  Definition.
  7. In the Additional Properties area, select Java Virtual
  Machine.
  8. In the Additional Properties area, select Custom
  Properties.
  9. Select the New box.
  10. In the Name entry field, type
  com.ibm.websphere.ejbcontainer.PK92914.
  11. In the Value entry field, type true.
  12. Select OK.
  
  
  The fix for this APAR is currently targeted for
  inclusion in Service Levels (Fix Packs) 6.0.2.39 and 6.1.0.29
  of WebSphere Application Server versions 6.0.2 and 6.1.0.
