Problems Runnins JBoss 3.0.0

Hi all,

I'm working on a project that involves EJBs and JSP, I'm going to use JBoss 3.0.0 + Tomcat 4.0.3 as the application server...

I've installed j2sdk1.4.0 and set the JAVA_PATH environment variable I've also set the JBOSS_DIST environment variable...

The problem is that when ever I run the Server and Load Internet explorer and type the URL: http://localhost:8080/

A page comes up saying:

"Apache Tomcat/4.0.3 - HTTP Status 500 - No Context configured to process this request

type Status report

message No Context configured to process this request

description The server encountered an internal error (No Context configured to process this request) that prevented it from fulfilling this request."

What seems to be the problem?!!

I'll be very thankful to anyone who can help me... ;)
