Do you have placed all required jars in the WEB-INF.lib directory of your application ?

Note that placing struts-api jars in a "common" directory of your server may cause Exceptions.

i do have struts.jar file in the WEB-INF/lib directory and i dont have it in any other 'common' directory but it doesnt seem to work !
