I am using jboss-3.2.1_tomcat-4.1.24 version. where will be compiled files placed, as like j2ee public_html folder?
If you mean the location of compiled JSPs, then check the following path, $JBOSS_HOME\server\default\tmp\deploy\server\default\deploy\work\MainEngine\localhost
This folder will contain a folder correspoding to your application folder in $JBOSS_HOME\server\default\deploy.
The compiled files (.java and .classes) are present here.
