Hi everyone,
I'm still chasing that old NotSerializableException... and I've got
some questions about the code. BTW, let me know if this should be sent
to a list besides jboss-user.
I've added my comments/questions inside the method in question:
public class HomeProxy extends GenericProxy {
//... lots of stuff skipped...
public Object invoke(Object proxy, Method m, Object[] args)
throws Throwable
{
// Normalize args to always be an array
// Isn't this a bug in the proxy call??
if (args == null)
args = new Object[0];
if (m.equals(toStr))
{
return name+" home";
}
else
{
// Delegate to container
// Optimize if calling another bean in same
EJB-application
--------------------
What's optimize and isLocal()? How do you set a bean as local or
optimized?
--------------------
if (optimize && isLocal())
{
return container.invokeHome(m, args,
tm != null ? tm.getTransaction() : null,
null);
} else
{
RemoteMethodInvocation rmi = new
RemoteMethodInvocation(null, m, args);
if (tm != null)
rmi.setTransaction(tm.getTransaction());
--------------------
The next line is where my process dies. Here's my diagnosis: on making
a new MarshalledObject, the rmi object should get serialized. Except
the setTransaction method gives the rmi object a Transaction from the
transaction manager. This transaction (TransactionImpl, right?) is
serializable. However, this transaction has a reference back the the
transaction manager, which is NOT serializable. This is corroborated
by the stack trace from the error I get, which I will provide after the
code.
--------------------
return container.invokeHome(new MarshalledObject(rmi));
}
}
}
The stack trace:
java.lang.reflect.UndeclaredThrowableException:
