This is a two-step process:

  1. Get hold of the ServletContext representing web2
  2. Get the RequestDispatcher from that ServletContext corresponding to servlet2

So, something like this, from inside servlet1:

ServletContext web1 = getServletContext();
ServletContext web2 = web1.getContext("/web2");
RequestDispatcher dispatcher = web2.getRequestDispatcher("/servlet2");
dispatcher.forward(request, response);

There's a big caveat to all of this - the container may not be configured to permit cross-context forwarding, since it's a potential security risk. If this is the case, getContext("web2") will return null.
