Thank you Johnny, To be specific this is my question Hi all
I am trying to pass an object from a tag to a servlet. i did the following, 1. In the tag class, i put: pageContext.getRequest().setAttribute("QList", list); The above Tag will go to a servlet, i need to read the above request attribute in the servlet, how can i do this?, i tried List<Integer> list = (List<Integer>)request.getAttribute("QList"); , but when i tried to access the read list, it gave me NullPointerException...What do u think?

Hi Mohammed, Cant say I really understand the question.... In general this is what the Session Objects are for.... So say you have a servlet and a JSP page.... and say the servlet makes the bean with the Array List in it.... then if you session.setAttribute("MyBean", MyBean); you can get it (MyBean) back when the next call comes into say the JSP page.... Now if you read up on this you will see you can also set 'request' objects.... and these are good for when you say dispatch a request to a JSP page from the servlet and want to pass a bean across. Anyway... if you just google for "servlet session and setAttribute".... you will be on your way... I think ;) This area of servlet programming is one of the things that make it such a powerful technology.
