Attempting to returning a list over RMI/IIOP results in serialization exception
-------------------------------------------------------------------------------
Key: OPENJPA-1060
URL: https://issues.apache.org/jira/browse/OPENJPA-1060
Project: OpenJPA
Issue Type: Bug
Components: jpa
Affects Versions: 2.0.0
Environment: JEE
Reporter: Jeremy Bauer
Returning a result list over RMI/IIOP invocation currently fails on trunk/2.0
with this exception:
java.rmi.ServerException: RemoteException occurred in server thread; nested
exception is: java.rmi.MarshalException: CORBA BAD_PARAM 0x4f4d0006 Maybe;
nested exception is: java.io.NotSerializableException:
org.apache.openjpa.jdbc.kernel.InstanceResultObjectProvider is not serializable
at com.ibm.CORBA.iiop.UtilDelegateImpl.wrapException(UtilDelegateImpl.java:748)
at javax.rmi.CORBA.Util.wrapException(Util.java:296) at ...
The problem is the result of storing the ROP in the userObject field of a
ResultList in the org.apache.openjpa.kernel.QueryImpl.toResult(..) method. -
res.setUserObject(rop). The ROP is not serializable so the RMI/CORBA layer
throws an exception.
