java.lang.NoClassDefFoundError: javax/jms/JMSException

Good day:

I am running Redhat Linux 7.3, JBuilder 7 and Joram 3.0.1 Open-Source Message Broker.

FIRST:

I have started my java REGISTRY with no problems with:

%rmiregistry 1099 &

THEN:

I have bound my SERVER with no problems in the registry as follows:

% java -Djava.rmi.server.codebase=file:///usr/local/LINKS_Newsgroup/classes/ Newsgroup_Server_Main &

THEN:

I start up my Joram 3.0.1 (Open source Message Broker) with no problem as follows:

%../../../jakarta-ant-1.5.1/bin/ant server0 &

and then:

../../../jakarta-ant-1.5.1/bin/ant classic_admin

THEN: I start my client in JBuilder 7. This shows a client dialog that has a login button. When i press the login button, it is meant to GET A REFERENCE to the SERVER that has been bound, THEN invoke a simple method: Here's the code as it appears in my login dialog class:

void login_button_actionPerformed(ActionEvent e) {

try{

LINKS_NewsgroupIF impl = LINKS_NewsgroupIF)Naming.lookup("LINKS_Newsgroup_Server");

impl.authenticateTutor(username.getText(), password.getText());

this.setVisible(false);

}//end of try

catch (java.rmi.RemoteException re) {

System.out.println("A wierd remote exception was thrown! " +

re.toString());

}//end of catch

WHAT'S THE PROBLEM then?

The "impl" object comes back ok. (i.e the debugger goes BEYOND THIS STEP WITHOUT throwing Naming Exception, etc).

But now that i have the "impl" instance, if i try to execute the method "authenticateTutor", then it throws the following exception:

A wierd remote exception was thrown! java.rmi.ServerError: Error occurred in server thread; nested exception is:

java.lang.NoClassDefFoundError: javax/jms/JMSException

MY QUESTION IS WHAT THE HECK JMSEXCEPTION has to do with executing a simple method through RMI?! Why is it doing that?

Thanx for any suggestions.
