subfolder in jsps causing ServletException

[buzz]

Hi,
My application is redirecting the url to a jsp in a sub folder.

String dispatch_url;
if((request.getParameter("action") == null) ||
(request.getParameter("action").length() < 1))
{
dispatch_url = "./action/home/"
}
else
{
dispatch_url = "./action/"
+ request.getParameter("action")
+ "/"
;
}

And I get the below exception;

<[ServletContext(id=6822497,name=applications,context-path=/application
s)] Servlet failed with ServletException
javax.servlet.ServletException: Failed to resolve path:
/applications/action/home/

I can't figure out the reason why this is happening.
Any clues?

Thanks in advance.
