Hi Could someone help me understand what am I doing wrong in the following code due to which I am getting this error:

Could someone help me understand it?

Thanks.

could you check if there indeed exists a request attribute called user when the jsp is rendered? (use <c:out /> for example) — Bozho

@Bozho: I have a propery private boolean enabled = true;, with a getter method for it, on my User domain object that I am using here as a backing object. When I try to retrieve ${user.enabled} on signUp.jsp it doesnt show anything, so I think there indeed is no 'user' available as a request attribute. And I am not able to understand why? — skip

@Bozho: I was able to get the signUp.jsp displayed to test ${user.enabled} because I had commented out the complete <table> element which had the <form:form> tag inside it. — skip

I was mistakenly using the wrong import for ModelAndView. I was supposed to use org.springframework.web.servlet.ModelAndView but the one I was mistakenly using was org.springframework.web.portlet.ModelAndView.

I've got the code working now.

Thanks :)
