Class Loader error

           Summary: Class Loader error
           Product: Tomcat 4
           Version: 4.0.2 Final
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: greg.hall@axa-insurance.co.uk


I get a java.lang.NoClassDefFoundError: javax/ejb/EJBObject when loading a JSP 
page. This does not occur running Tomcat 4.0.1 on the exact same web app (I 
have placed the app in an external directory). 

The j2ee.jar is in both the WEB-INF\lib directory and on the system classpath. 
The JSP page uses a JavaBean which in turn uses an EJB from a JBoss server 
running in a seperate JVM.

Running on Windows NT 6a with J2SE 1.4 and J2EE 1.3

I am baffled ! Please help !

The error page that is displayed when I access the page is as follows:

Apache Tomcat/4.0.2 - HTTP Status 500 - Internal Server Error

--------------------------------------------------------------------------------

type Exception report

message Internal Server Error

description The server encountered an internal error (Internal Server Error) 
that prevented it from fulfilling this request.
