I just follow the mod_webapp documentation add the following in httpd.conf
LoadModule webapp_module libexec/mod_webapp.so
WebAppConnection conn warp localhost:8008
WebAppDeploy examples conn /examples
I found that when running the tomcat 4.0.1 solely (Apache+Tomcat4.0.1). It works. However, when I running the tomcat with jboss (Apache+Jboss 2.4.4+Tomcat 4.0.1)
(run_with_catalina.sh). It won't work. The port 8008 for the connector is not listening.
