Hi
We have been partially successful in integrating JBoss 3.0 with Tomcat 4.1.8. Basically, we opted to do this in order to take advantage of Tomcat 4.1.8's excellent User Admin application.

In order to do this, we changed the ENTITY entry in Tomcat4-service.xml file to point to the Tomcat 4.1.8 install directory and added some classpath entries after it for the Catalina.jar for Tomcat4.0. that came bundled with JBoss3.0 because it needed the XmlAction.class file (which is not availalbe in the Catalina.jar file that came with Tomcat4.1.8)

Anyway, the net of it is, we are able to use this combination up to a point, but it is flaky. In order to run the Admin App that came with 4.1.8, we created a war file from the admin directory of webapps in Tomcat4.1.8 and deployed it to the <JBoss3.0_Install>/server/default/deploy directory. It seems to deploy successfully, but when we log in to the app, it says the the following message. Can anyone tell us what to do to make it work ?

Thanks in advance,
S.D

Here is the file containing the messages we get
