RE: javax.jms.MessageFormatException

That worked.  I had the openjms client jar under the common folder in
tomcat.  I moved it to the lib folder for each of the applications and it
works.

I suspect the problem is occurring because the openjms client jar is in a
different
class loader to that of your app. If you include the client jar in your
webapp, along with
the jar containing BeanUser, the problem should go away.

 Subject: RE: [openjms-user] javax.jms.MessageFormatException



 The Sender and Receiver are running under two seperate JVMs

 Here is a sample of the stack using the code you provided:

 java.lang.ClassNotFoundException: com.rockwell.powersystems.beans.BeanUser
 at
 org.apache.catalina.loader.StandardClassLoader.loadClass(StandardClassLoader.java:844)

 at
 org.apache.catalina.loader.StandardClassLoader.loadClass(StandardClassLoader.java:709)

 at java.io.ObjectInputStream.readObject(ObjectInputStream.java:339)
 at
 org.exolab.jms.message.ObjectMessageImpl.getObject(ObjectMessageImpl.java:215)


 This would appear to be a class path issue. I added a line of code to test
 the classpath just before the message.getObject();:

 com.rockwell.powersystems.beans.BeanUser testUser = new
 com.rockwell.powersystems.beans.BeanUser()
 logger.info("Test User: " + testUser);

 2005-07-05 09:07:45,101 INFO com.rockwell.amts.actions.RetrieveUserProfile
 - Test User: com.rockwell.powersystems.beans.BeanUser@113cd63

 The only thing I can think is the the multiple JVM is causing a signature
 issue on the class under Linux.

 The object is failing to deserialize.
 Have you included the bean and its dependencies in your classpath
 on the Linux client? Not clear from your post if the sender and receiver
 are in the same JVM.

 You can get the root cause of the problem by:
 try {
 Object obj = message.getObject();
 } catch (JMSException e) {
 e.getLinkedException().printStackTrace();
 }

 Subject: [openjms-user] 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?
