HTTP Status 405 - HTTP method GET is not supported by this URL

I get the following error? what could cause such an error? the examples work fine. I have an old servlet, an another webapp application, that works fine, but whenver i try to to access my new servlet, it gives me that error. Where should i be looking for in order to solve this?

Actually, i fixed the problem, and if u ever encouter this problem this is the reason:

In my doGet method I had like this:

public void doGet(HttpServletResponse res, HttpServletRequest req)...


when in fact the arguemtnts have to be in such that HttpServletRequest should come first and then HttpServlet res, so the correct signature is:

publiv void doGet(HttpServletRequest req, HttpServletRespons res).....
