cant remove Attributes from request scope

[RKarneim]

 

Hi,

 

I have tryed to run the struts-example with tomcat inside JBuilder4. This causes the following exception:

Error: 500

Location: /registration.jsp

Internal Servlet Error:

javax.servlet.ServletException: cant remove Attributes from request scope

Does anyone know something about that? Anything I missed?

The example runs pretty well with a 'standalone' tomcat.

 

Thanks,
