Dear Vineesh, The params interceptor also known as parameters interceptor is used to set all parameters on the valuestack.It is found in the default stack bydefault. So you don't need to specify it explicitely. It gets all parameters by calling the getParameters() method of ActionContext and sets it on the valuestack by calling the setValue() method of ValueStack.
Note: If you specify any interceptor for the action explicitely, default interceptors will not be available for the action class.
