Solution
if we want to use struts tags then request must pass through servlet filter. It can be done by mapping all the request to servlet filter by using. For these kind of issues check with all ur requests (actions) mapped in struts.xml.

In my case the issues was different and strange, In JSP null array list was being iterated using struts tags some things like below 

<c:forEach var=”itemImage” items=”${items.getImages()}”> where items.getImages() was null.
