I need to check for null for one of my request attributes. Consider this , In my login page i check for a request attribute which contains the message saying whether the user is invalid. That is for normal login and specifying invlid login i am using same JSP. If the user is invalid, I set a request attribute with a message. For this i need to check for the request attribute itself for null. How can i check this using logic:equal tag or c:if tags. i dont want to use scriptlets.
Basically in any scope how can i check a value or an attribute for null using logic:equal or c:if or other tag
please help me on this regard.
