PROBLEM:
-------

If i access my application using the tomcat (8080) port,
things seem to be working fine.

However, if i use apache (port 80), it seems to forward
JSP requests perfectly fine, but when forwarding servlet
request (like http://<domain>/<context>/servlet/myServlet?
it throws an error

HTTP 404 Not Found
The requested URL /servlets-examples/servlet/HelloWorldExample
was not found on this server.

Any help in the above regards is highly appreciated.

thanks,
felix
