Getting Value in Jsp using UseBean

Question

Friends I am sending My List from Action class, here is the code

//Code of my Action class

List matchUsersInTracker = new ArrayList<User>();

DynamicQuery userTrackerquery = DynamicQueryFactoryUtil.forClass(User.class, PortalClassLoaderUtil.getClassLoader())
    .add(PropertyFactoryUtil.forName("userId").in(DynamicQueryFactoryUtil.forClass(UserTracker.class, PortalClassLoaderUtil.getClassLoader())
    .setProjection(ProjectionFactoryUtil.property("userId"))));

matchUsersInTracker = UserLocalServiceUtil.dynamicQuery(userTrackerquery);

//Pass this entire List of user 
if(matchUsersInTracker!=null)
{
    actionRequest.setAttribute("match_base_Users", matchUsersInTracker);
}

//code in My Jsp -------

Now in Jsp I am using useBean:

<jsp:useBean id="match_base_Users" class="java.util.ArrayList"  scope="request">
</jsp:useBean>

It gives me ClassCastException, now converting each and every element to user class one by one in for loop isn't the feasible way.

Increases loading time of my jsp.

So any guesses how can I send a User List from ActionClass to Jsp

I also referred this question but was not able to come out with a resolution.

I just want to display data in jsp

You don't need <jsp:useBean> at all if you're already using a MVC framework which manages the beans in the desired scope. The <jsp:useBean> is only useful if you aren't using a MVC framework which managed the beans by itself.

Get rid of it and just access it by ${match_base_Users} directly.
