checking for bean in session

[pendse anagha]

Hello ,
I have a login Screen - and after Login I am storing a plain JavaBean on session .

In all the JSP pages - I want to show the name of the user logged in ( from the Java Bean on session )

For this I am using a common JSP
This is also used on the Login Screen

I want to first check - if the simple Java bean is on session

However - neither logic resent nor logic:empty seems to work

Any help would be greatly appreciated

logic resent should work. If you don't post what you are trying, no one can tell you what you are doing wrong.

yes - I guess with out the code - its going to be difficult

Here is what I am trying :

  
<logic :-P	 resent name="<%=Constants.USER_OBJECT%>" scope="session">
I SHOULD NOT BE HERE SINCE NO BEAN IS ON SESSION
</logic :-P	 resent>
<logic:notPresent>
I SHOULD BE HERE SINCE NO BEAN IS ON SESSION
</logic:notPresent>

Though the first time there is no bean on session - I enter the condition of Not null and I get the print :
" I SHOULD NOT BE HERE SINCE NO BEAN IS ON SESSION "

Thanks ,

Remember that the notPresent tag needs the same attributes as the present one - it doesn't get them by magic.

If you don't like specifying a test each time, look at JSTL's core library. c:choose allows something similar to if/else with when/otherwise:

<c:set var="user"><%=session.getAttribute(Constants.USER_OBJECT)%></c:set>
<c:choose>
  <c:when test="${empty user}">
    I SHOULD NOT BE HERE SINCE NO BEAN IS ON SESSION
  </c:when>
  <c:otherwise>
    I SHOULD BE HERE SINCE NO BEAN IS ON 
  </c:otherwise>
</c:choose>
