I can't seem to be able to get hold of a EJB's home interface using the following simple code. This code works when the Web Application runs under IBM's Websphere and as a standalone app, but not when the application is transfered to Tomcat.
The code is:

// Initial context already found Okay
// Simple look up
Object objref = ctx.lookup("StockHoldings");

StockHoldingsHome home = (StockHoldingsHome) javax.rmi.PortableRemoteObject.narrow (objref,StockHoldingsHome.class);

// Get hold of the remote interface
m_StockHoldings = home.create(); // This fails

The error message is:
RemoteException occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.net.MalformedURLException: no protocol: Files/Apache

This error occurs even when running sample EJB from Text books.

Both the JBOSS and Apache Tomcat installation have not been changed - they're installed as default straight out of the box.
Any suggestions?

Thanks in advance.
