Hi:
    I build the Geronimo and its server successfully. When I enter http://localhost:8080/geronimo-web-console to access the JMX Agent View. The page comes out the following message:
 
HTTP ERROR: 500
No Java compiler was found to compile the generated
source for the JSP. This can usually be solved by
copying manually $JAVA_HOME/lib/tools.jar from the
 JDK to the common/lib directory of the Tomcat server,
followed by a Tomcat restart. If using an alternate Java
compiler, please check its installation and access path.
 
RequestURI=/geronimo-web-console/

Powered by Jetty://

This seems a problem cause by classpath setting. But, I don't know where to solve this. Geronimo use Jetty as its web container, not Tomcat. Does anybody know how to solve this...
