RMI issue with Tomcat

Question

Hi All,
I have an RMI system, that in command line works perfectly, as expected. However, I have transferred my Client to Servlet and am running it though Tomcat. Now when ever I try and invoke a remote method I receive an error message.
The error is generated as a result of catch statement for the following:
server = (Server)Naming.lookup(fullname);I know the Client code is being evaluated as it generates the HTML error message from the catch. Using a System.out.println and the Tomcat log files I caught the error and wrote it to a log file. It was as follows:
Caught an exception doing name lookup on rmi://localhost/Bank-Server: java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
     java.lang.ClassNotFoundException: ServerImpl_Stub (no security manager: RMI class loader disabled)
Caught an exception doing name lookup on rmi://localhost/Bank-Server: java.rmi.ConnectException: Connection refused to host: localhost; nested exception is:
     java.net.ConnectException: Connection refused: connect

java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
     java.lang.ClassNotFoundException: ServerImpl_Stub (no security manager: RMI class loader disabled)I can see from the error that it might have something to do with a security manager? I have read a little about it and when running the security manager a special command needs to be entered at runtime to invoke the policy? How on earth is this done in a Web application situation?

Connection refused: connectIt could be some configuration problem.
