I have an old servlet application which used old servlet API. The URL was like : http://server/servlet/MyServlet . Now I upgraded the server and reorganized the file struture so the new URL is : http://server/myapp/servlet/MyServlet, in which I created an application called "myapp" and put all .class in myapp/WEB-INF/classes/.

Now I want the old link to be automatically redirected to the new link. I want to use <servlet-mapping> and here is how I tried --
<servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>Myservlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MyServlet</servlet-name>
<url-pattern>/servlet/MyServlet</url-pattern>
</servlet-mapping>

But it does NOT work. Can somebody help ?
Thanks.

Frank,
I think you need to deploy a separate web app that does not have myapp as a context root. It would have one servlet that redirects all requests to the URL.

Frank, you are not misspelling MyServlet as Myservlet by any chance, are you?
You may want to post more details of what 'does not work' in this case mean. For example, whether you get a 404 error or some other exception or a blank page or whatever.

first of all, there is no misspelling problem although I might make some typo here. Secondly the error msg was "File Not found". Now I guess I know what's going on --- Since this web.xml is contained in this "myapp", there is no way that I can map the "/myapp/servlet/MyServlet" to "/servlet/MyServlet", right ?

Another question is -- if the URL is like http://server/myapp/servlet/MyServlet?param=abc, then how to redirect ? (This case how to carry the "param=abc" ?)
