Hi,

I am working on Portlets application on webspear portal. One of my Jsp is giving "NestedNullException". I am using <display:table> tags from taglib(<%@ taglib uri="http://displaytag.sf.net" prefix="display"%> . If i remove this tag it is showing empty page. if i put it it is thorwing the exception. Can anyone tell me how to resolve the problem. the stacktrace is below.

Please do not post the same question more than once. It causes confusion and duplication of effort as the community tries to help everyone.
