Configuring home dir for webapps

Hi,

I'm on Apache/2.0.59 (Win32) mod_jk/1.2.21 Tomcat 5.5.9 and having a hard time configuring home or Root dir for each domain.

For eg. domain1.com works as http://domain1.com/dir1, but not directly. How do I set dir1 as domain1's root?

I tried the apache <virtualHost> directive, which correctly redirects but then the jsp app doesn't work, contents of index.jsp are displayed in the browser.

I also tried several <host> combinations in server.xml, but nothing worked.

Any help greatly appreciated. Thanks
