Hi Vasu,
If you want to forward the servlet2 to servlet3 you shouldn't obtain the
writer or the output stream in servlet2.
So delete the writer and the related lines in servlet2. try the following:
///////////////////////////////////////////////////////////////////////
public class HelloWorldExample2 extends HttpServlet {
public void service(HttpServletRequest request, HttpServletResponse
response)
{
try
{
getServletConfig().getServletContext().getRequestDispatcher("HelloWorldExample3").forward(request,
response);
}
catch(Exception ex)
{
ex.printStackTrace();
}
}
}
///////////////////////////////
i guess servlet2 n servlet3 are in the same directory, if so u can refer to
servlet3 directly as above. else change the path as is reqd, relative to the
servlet2
Have servlet3 as it is..
It shld work!!!!!
