****Oups, I forgot to attach the files
Hi,
I found a problem: Each time a bean method throws a business exception, I'm
unable to commit or rollback the transaction initiated by the client ( but
it 's rolled back later by the jonas TM's timeout). I mean that the rollback
method is called on the UserTransaction object but the rollback isn't
propagated to the jonas server.
I looked at the source code to understand what's going wrong. And I found
that in the org.objectweb.jonas.rmifilters.RemoteStub class the
propagationContext is not well handled.
public class RemoteStub extends java.rmi.server.RemoteStub {
......
public void invoke(java.rmi.server.RemoteCall call)
throws java.lang.Exception, java.rmi.MarshalException {
....
// Add it to output args
try {
ObjectOutput out = call.getOutputStream();
out.writeObject(pctx);
} catch (IOException e) {
throw new MarshalException("error marshalling propagation context", e);
}
// >>>>>>>>>>>>>> Problem seems to be here
// Invoke remote method call
ref.invoke(call);
// >>>>>>>>>>>>>>
// Extracts PropagationContext from input args
try {
ObjectInput in = call.getInputStream();
pctx = (PropagationContext) in.readObject();
} catch (IOException e) {
throw new UnmarshalException("error unmarshalling propagation context",
e);
}
....
}
.....
}
Indeed the exception thrown by the bean method prevents the interposition
class from reifying the exception and returning the right
"PropagationContext" to the client.
I have designed a solution that makes the interposition class handle the
business exception. It inserts it into the PropagationContext object. The
RemoteStub class manages it and reifies it to a client exception. So, the
PropagationContext is ok and the client is able to commit or rollback its
transaction.
I have done changes to the 2.2.6 source code. I enclose the modified files.
You can locate changes with the //TGU comments I inserted.
