Java EE (Java Enterprise Edition) General Discussion

Allow me to repeat something I posted in news:alt.apache.configuration, as I do not know where else to ask for help... Hints for better places to ask these questions are appeciated!

I want to create a kind of filtering proxy. So, I have set up Apache to work with Tomcat 3.2.3 (mod_jk) and pass all requests of some virtual hosts to Tomcat, to have it handled by my filter servlet. It works great, except for two things:

-1-
If I have an index.html in Apache's htdocs, then calls to the virtual host are not always delegated to Tomcat. Like "my.virtual-host.blah" and "my.virtual-host.blah/non-common-name.html" are delegated to Tomcat, but "my.virtual-host.blah/index.html" (or in general: any document name that also happens to be known to the web server) is served by Apache itself.

-2-
I cannot prevent jsp files to be handled by the JSP thing in Tomcat (instead of calling my filter servlet), even although I do not explicitly map *.jsp. I am not including the Tomcat generated conf/mod_jk.conf-auto. And I removed the global Tomcat conf/web.xml. How does Tomcat still recognize the *.jsp files?

Any clues?

Some more details below. I feel stupid to bother you with this while I cannot provide you with all the details, but I forgot to send the Tomcat server.xml to my home address... I know I mapped the root to my filter servlet context (either mapped "" or "/"). I removed anything that seemed to refer to JSP files. I also defined virtual hosts (in server.xml), but removed them again it as it did not seem to have any effect. It all works fine, except for the problems above. At least for the index.html problem, I really think I missed something in the Apache server settings?

While compacting the details below I noted something. I cannot test it now, but should I have uncommented "BindAddress"? Ooops, I also just read "You may use the command line option '-S' to verify your virtual host configuration". Cannot test that now either, but all comments appreciated!

Thanks a lot,
Arjan.
