Using EJB via RMI

[Xavier Fabreguettes]

Hi,

I was wondering about what happens when you have a client application (plain java class) invoking a method against an EJB via RMI.

Say that the Remote interface is something like

void doStuff(String param) throws RemoteException,MyException;

where MyException is an application exception written by the bean provider (hence packaged up in the same jar as the bean itself).

For this invocation to work successfully, do specific constraints apply to MyException? (i.e. implementing Remote or Serializable)?

Thanks for your help.

I think, you may not throws MyException in this method.

Because you can wrapped MyException into RemoteException.

Application exception propagates to the Client as it is. No worries.

Exception class extends java.io.Serializable. There is no need to implement Remote interface.

Exception class extends java.io.Serializable. There is no need to implement Remote interface.

Makes sense. Forgot to check, it should have put me on the right track! Thanks for your help.
