EJB/Tomcat vs. EJB/J2EE?

[Rune Engseth <ra...@nextra.com>]

I have the following problem:

I'm using tomcat for my servlets and jsp's.
I have also deployed an EJB using the J2EE server
and deployment tool.
My servlet is doing all the JNDI lookup things, and 
calls a method on the EJB :

- **
Context initial = new InitialContext();
Object objref = initial.lookup("EMailer");
EMailerHome home = (EMailerHome)PortableRemoteObject.narrow(
		   		objref, 
		   		EMailerHome.class);
EMailer mailer = home.create();
mailer.sendMail(param, param, ...)
- **

If deploying my servlet on the J2EE server, this works fine.
However, when I deploy my servlet on Tomcat, I get the following error
when trying to cast the object using the narrow method:


Class: com.sun.corba.ee.internal.iiop.CDRInputStream$1 ( my debug info !!)

I have made sure that the correct class file is in the class path etc, so
why do I get this error on Tomcat and not on the J2EE server??
