} } [/code] Please suggest how i can achive the same. Thanks in Advance Shafquat
1.) Use the new PrepareAndExecute Filter Code: [LEFT]<filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter>[/LEFT] 2.) How looks your Action Configuration? 3.) Do you call the action or the JSP?
