JSP, Debugging, Eclipse

[peter.kolbe]

Hi Developers,

using MG2008Enterprise, Tomcat and JSP-Installation.
I installed some own JSP files and access to own Java classes in a *.jar file - everything is working fine.
Question: How can I debug that application using Eclipse (3.2.0)?
The MG Server is running on a seperate machine. Where do I have to start Eclipse environment, on my dev-machine or on server? I tryed on server, there I get the message, that ports (8080,8009) for Server are required. If I stop the MG tomcat server, then debugging is starting, but environment shows unresolveable token, as
<%@ page import="javax.servlet.jsp.*" %>
or
getServletContext()

Any hints on topic debugging JSP, Java in MGE2008 would be appreciated. Thank you!
Regards,
Peter

the invisible token in first message is a import directive for javax.servlet.jsp.*
