jetty rewrite rule

Question

I'm currently unable to redirect/rewrite my application in Jetty6. I use Apache as a front-end proxy since I host non-Java based applications as well. My apache2 configuration uses ProxyPass:

  ProxyRequests Off

  ProxyPreserveHost On

  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>

  ProxyPass / http://localhost:8080/
  ProxyPassReverse / http://localhost:8080/

My directory structure is standard:

  /var/lib/jetty/webapps/
        /root/
        /app1dir/
        /app2dir/

I want to be able to redirect traffic from:

 /var/lib/jetty/webapps/root/somedir/*

to:

 /var/lib/jetty/webapps/app1dir/somedir/*

I've tried using Apache rewrite rules as well as .htaccess files with no luck.

Jetty still throws a 404.
