Hi All,
I am using JavaWebserver2.0 on Solaris.
I am facing a problem.
I have a few servlets and jsps.
Consider the following sequence
login.jsp ---> serv1 ----> ParmsMain.jsp
Whenever I restart my Javawebserver2.0 and start with the login.jsp
I get the following error:
The servlet named range.RangeServlet at the requested URL
http://cobra01:9085/servlet/range.RangeServlet
reported this exception: java.lang.NullPointerException. Please report this
to the administrator of the web server.

........
My servlet has the following code :
if ( func == 1)
getServletContext().getRequestDispatcher("/ParmsMain.jsp").forward(req,res);
The jsp needs to be recompiled. Then it works fine.
But If I replace this code snippet with
res.sendRedirect("/ParmsMain.jsp")
I no longer get the problem. But in this case the values from the login.jsp
are not passed to the ParmsMain.jsp.
Could somebody solve this problem.
Thanks,
JS
