The jdev version is 10.1.3 and the application is a struts application using struts 1.2.9
The index.jsp file just contains an redirect to Welcome action. Following are the Lines :
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<logic:redirect forward="welcome"/>
When i directly try accessing the welcome.do action i get the Following error in the browser
404 Not Found

I have been struggling on this for the past 2 days. Can someone help me on this.
Thanks in advance.

Hi Ninad,
I've no idea what the problem is but I would start by looking at possible jar incompatibilities:
12-Jun 17:14:07 ERROR (ActionServlet.java:init:364) Unable to initialize Struts ActionServlet due to an unexpected exception or error thrown, so marking the servlet as unavailable. Most likely, this is due to an incorrect or missing library dependency.
Good luck,
Heidi
