Iterating over ArrayList items with JSTL forEach

I'm having problem running over ArrayList items and displaying them in JSP file.

Here is my bean:

public class UsersList {
    private ArrayList<UserDetails> users = new ArrayList<UserDetails>();

    public ArrayList getUsers(  ){
        return users;
    }

    public void setUsers(ArrayList<UserDetails> users){
        this.users = users;
    }
}

users contains UserDetails which is simply class with 3 String properties: email, username, password

Now I am trying to display the details in a table.. first in index.jsp I have those commands:

            UsersList bean = new UsersList();
            bean.setUsers(db.getUsersList()); // getting all user deatils from database into the list
            session.setAttribute("bean", bean);

            RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/adminPage.jsp");
            dispatcher.forward(request, response);

And now on adminPage.jsp when I should display the table containing the users details, its displays nothing. Here is the code:

<c:forEach var="current" items="${bean.users}" >
<tr>
    <td>${current.email}</td>
    <td>${current.username}</td>
    <td><input type="checkbox" name="delete" value="${current.email}"</td>
</tr>
 </c:forEach>

Any idea what's the problem here?? Thanks.

Check if your prefix "c" points to the right tag library.

It should be

"http://java.sun.com/jsp/jstl/core"

If that does not work, check if there is mistake in the logic of populating the data.

Since your adding the object to session you need to access it from sessionScope in EL.

<c:forEach var="current" items="${sessionScope.bean.users}" >
<tr>
    <td>${current.email}</td>
    <td>${current.username}</td>
    <td><input type="checkbox" name="delete" value="${current.email}"</td>
</tr>
 </c:forEach>
