getRequestDispatcher forwarding across applications

Is it possible to use the RequestDispatcher.forward() method to forward to a servlet in a different context path?

For example:

I have the following jsp:
...that tries to forward to:

Here is the code that I am using in index.jsp:

RequestDispatcher rd = request.getSession().getServletContext().getRequestDispatcher("/app2/myServlet");

It returns null.

I could use:
But that sends the response back to the user before requesting the servlet, and would rather not use it if possible. :-/

Look at:
public ServletContext getContext(java.lang.String uripath)

Depending on the container, you may need to do some configuring (lower security) to allow this.
In Tomcat, you would set the crossContext property to true in your <Context../> entry.

Any idea how to get another app context using ServletContext.getContext(String uripath) in Weblogic 8.1?
