hi,

Firstly, I am very new in JBoss, absolute beginner.

I have downloaded the JBoss 4.0 intergrated with Tomcat 5. And when I run it for the first time, and then go to the web console: http://localhost:8080/jmx-console/

I received error like this:

type Exception report

message

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

exception

org.apache.jasper.JasperException: Unable to compile class for JSP

root cause

Unable to find a javac compiler;

note The full stack trace of the root cause is available in the Apache Tomcat/5.0.28 logs.

Does it have something problem with Tomcat ?

Could anyone please help me to solve it ? Do I need to set any classpath or any new environment variables in Windows XP ?

Thank you very much.
