How to read List object in JSP using OGNL tags

Question

My requirement is to read Objects of List from Session in JSP using OGNL.

In my action class,

Employee emp1 = new Employee();
emp1.setName("xyz");

Employee emp2 = new Employee();
emp2.setName("123");


ArrayList list = new ArrayList();
list.add(emp1);
list.add(emp2);

session.setAttribute("listObj", list);

So am trying to check name in Jsp pseudo code ::

`IF TEST ="#session.list.get(0).getName()"=="xyz"
print :: xyz user.
ElSE
   print :: guest user..`

Thanks Rajesh

Your pseudo code is here.

IF TEST ="#session.list.get(0).getName()"=="xyz"
print :: xyz user.
ElSE
print :: guest user..

The listObj is actually session-scoped attribute. So you access it in two ways:

1. #session.objectname or
2. #session['objectname']

You can use equals() method for comparing strings.

   <s:if test="%{#session.listObj.get(0).getName().equals("xyz")}">
       <h2>xyz user</h2> 
   </s:if>
   <s:else>
       <h2>guest user</h2>          
   </s:else>
