Few days back I have upgraded tomcat  from 4.1.29 to 5.0.25 ...

When I deploy  the war file in Tomcat 5.0.25 , and tried to login into the web
page using username and password , the control passes over to next page and in
that page links are there to Edit or Delete a User , when i am clicking on the
link "Edit" i am getting the following error

"java.net.MalformedURLException: Path . does not start with a "/" character"

If the same war file is deployed in Tomcat 4.1.29 ... its working fine  .... here
i am able to edit user info We are using a cocoon frame work  in our project  ,
When ever You click on the Edit link , control goes to Sitemap and searches for
the suitable pattern and calls the particular action

I am also pasting the Stack Trace of the Error :
