Issue With Java Request Dispatcher Which Having A Single Query String With Value "" For Weblogic (Doc ID 1268289.1)

Last updated on APRIL 26, 2018

Applies to:

Oracle Weblogic Server - Version: 10.3.3 and later   [Release: and later ]
Information in this document applies to any platform.

Symptoms

HTTP forward requests that are invoked with a trailing '?' and without a GET parameter fail with a 404 error.

For example please see the following code snippet.

urlAdd = ""

javax.servlet.RequestDispatcher dispatcher = getServletConfig().getServletContext().getRequestDispatcher("/CheckAvail?"+urlAdd);
dispatcher.forward(request,response);

If this is used in any other server, the requested Page is loaded. If used in WLS it gives 404 Error.
