How come request.getPathInfo() in service method returns null?

Question

I wrote Front Controller Pattern and ran the test. Somehow request.getPathInfo() is returning null when it should return the path info.

According to the Javadoc:

Returns any extra path information associated with the URL the client sent when it made this request. The extra path information follows the servlet path but precedes the query string. This method returns null if there was no extra path information.

You don't have any path info when using a prefixed mapping (*.do, in your case).
