Thanks Dave, if this violates the mailing list policy then I'm sorry for that.

But the amazing thing is that I'm not getting any sort of error in log with descriptive information. The application is working very fine at our end, also for most of the users only few people are getting NullPointer Exceptions.

Whenever they are trying to search a project, the application searches it in the database and open the result in a new window. And the error is displaying in that window.

==================

Error.jsp, timeout.jsp, and NotAuthorized.jsp are three error pages in my application.

Let me know if I'm wrong at any point.

Hi friends I am facing the following error. I hope the execute method is not
working. This is working fine few minutes ago. Suddenly started this error.



No configuration found for the specified action: 'executePoPSearch.action'
in namespace: '/p'. Form action defaulting to 'action' attribute's literal
value.



My config in xml is



<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts
Configuration 2.0//EN"

  "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

   <package name="PoP-SearchConfig" namespace="/p" extends="PoP-default">


       <default-interceptor-ref name="defaultStack" />





       <action name="executePoPSearch"
class="org.paradigmpop.mypopproject.search.actions.ExecutePoPSearchAction">

           <result name="success">/p/pop_search_results.jsp</result>

           <result name="input">/p/pop_search_results.jsp</result>

           <result name="error">/p/pop_search.jsp</result>

       </action>

</package>

</struts>
