I have a servlet that looks something like this:
public class ExampleServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.getWriter().println(request.getPathInfo());
}
}
with a web.xml mapping like:
<servlet>
<servlet-name>example</servlet-name>
<servlet-class>com.example.ExampleServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>example</servlet-name>
<url-pattern>/example/*</url-pattern>
</servlet-mapping>
and it gives me exactly what I expect... If I go to http://localhost:8080/example/foo it prints "/foo". However, if I change the servlet to forward to a JSP file:
public class ExampleServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// do something here to check the value of request.getPathInfo()
request.getRequestDispatcher("whatever.jsp").forward(request, response);
}
}
then when I check the value of getPathInfo() it now reports "whatever.jsp" instead of "foo".
- Why has this changed before it's been forwarded to the JSP?
- How can I detect what URL the user's looking for?
EDIT: Just in case it matters this is on Google App Engine. Don't think it should though.
