Apache doesn't process J2EE directly - you configure it to pass JSP and servlet requests to Tomcat (or whatever J2EE server you like). There's a Tomcat-Apache HOWTO at http://jakarta.apache.org/tomcat/tomcat-3.3-doc/tomcat-apache-howto.html. The simplest of the several ways to do is is via mod_jk and the ajp13 connector - for me, anyway. The magic word to look for to get a client-side applet to talk to a server is "URLConnection".
Customer surveys are for companies who didn't pay proper attention to begin with.
