Hi All,

i am facing a strange problem with struts2 action from a webpage i am
opening up a popup window.
there are some simplle input fields in the popup window and a submit button
this is the action call from the popup window

<s:form action=*"CreateChallanJob"* name=*"createChallanJob"* id=*
"createChallanJob"*>

and in the xml configuration file

<action name=*"CreateChallanJob"* class=*
"com.raisonne.billsmart.challan.action.CreateChallanJob"*>

<result name=*"success"*>/Templates/Challan/CreateJob.jsp</result>

<result name=*"error"*>/Templates/Challan/CreateJob.jsp</result>

</action>

but when ever i am hitting save button from my popup window i am getting
error with error code 500 below is the output from the console.
