Hi Folks,
I'm getting the exception below when I try to invoke an Entity Bean's
finder method from inside a Stateless Session Bean. The finder method
is:
public abstract findByName(String name1, String name2) throws
FinderException, RemoteException;
This looked like a serialization problem while sending args through RMI,
so I added some debug statements to the HomeProxy code to check that the
HomeProxy.invoke() method is receiving Serializable classes. It is...
it gets an Object[] containing the two String arguments, as expected.
I have NO IDEA where else to look for this error, since most of this
trace is in Sun's code. HELP!!
Here's how the Entity Bean's finder looks in the Jaws.xml:
<finder>
<name>findByName</name>
<query>name1 = {0} AND name2 = {1}</query>
<order></order>
</finder>
The exception is:
[MyStatelessSessionBean] java.rmi.ServerException: Exception occurred;
nested exception is:
