javax.jms.MessageFormatException

Hello all,

I have a quick question.  I am running OpenJMS 0.7.6.1 on a RedHat
Enterprise Linux Server w Java 1.5.

I have a JavaBean defined as:

public class XyzBean extends Object implements Serializable

I place the Bean on a Queue using the

ObjectMessage msg = session.createObjectMessage(xyzBean );

I retrieve the message with:

        QueueReceiver reciever = session.createReceiver(queue, selector);
        ObjectMessage message = (ObjectMessage) reciever.receive(2000);
        XyzBean xyzBean = (XyzBean) message.getObject();

However this will throw a javax.jms.MessageFormatException: package.Xyzbean
error

I run the same code on a Windows 2000 Server running Java 1.5 and OpenJMS
0.7.6.1 and it works without a problem.

Does anyone know what might be causing this issue on the Linux Machine?
