apache + mass virtual hosting +tomcat please help

[Cristi Banciu <mufa@alibiduba.bounceme.net>]

Hi,

I have configured apache with mass virtual hosting by adding following 
line to apache's conf files.

VirtualDocumentRoot /var/vhosts/%0/httpdocs/
and everything seems to work just fine with a little exception.

Few virtual sites needs tomcat in order to work. I have installed 
tomcat4 and mod_jk2, but I have no idea how could I tell that
www.tomcatsite.com which is /var/vhosts/www.tomcatsite.com/httpdocs is a 
site that requires java ?

Sorry if I am confuse!
