Hi !

I've been struggling the whole day to fix the following problems ( this is the first bean I've ever deployed !) :

*** SimulatorProcess executing ***
 *** EJBOperation.execute ***
 *** got the home handle ***
 *** bean created....{O_P=[ejb, irn, arf], C_O_I=2}
java.rmi.MarshalException: CORBA COMM_FAILURE 0x4942f306 Maybe; nested exception is:
org.omg.CORBA.COMM_FAILURE: purge_calls:1186 minor code: 4942F306 completed: Maybe
org.omg.CORBA.COMM_FAILURE: purge_calls:1186 minor code: 4942F306 completed: Maybe
at com.ibm.rmi.iiop.Connection.purge_calls(Connection.java:1185)
at com.ibm.rmi.iiop.Connection.doReaderWorkOnce(Connection.java:2356)
at com.ibm.rmi.transport.ReaderThread.run(ReaderPoolImpl.java:138)

Code that looks up and executes the business method :
( this code is a standalone app launched from WSAD launch client )
---------------------------
Object homeObject = initConx.lookup(jndiName);
LinkReceiverSimulatorHome simBeanHome = (LinkReceiverSimulatorHome)
javax.rmi.PortableRemoteObject.narrow(homeObject, LinkReceiverSimulatorHome.class);
System.out.println(" *** got the home handle ***");

LinkReceiverSimulator receiverBean = simBeanHome.create(); System.out.println(" *** bean created...." + context );

OperationParameter oParams[] = new OperationParameter[operationParameter.size()];
oParams = (OperationParameter[])operationParameter.toArray(oParams);

receiverBean.executeOperations(oParams,contextClone); //!!!
System.out.println(" *** business method completed ");
---------------------------

Please help !!!

Here are my observations :
* 2 args are passed to executeOperations() . The first arg is the one that is causing the MarshalException. This was originally and ArrayList which I changed to object array instead.

Did you make sure that all classes passed are serializable (also all contained objects to have to be serializable)... Make sure this is done

Second: Did you re-generate stubs / skeleton asf before deploying?
