I SKIP THE REST OF THE CODE-->
the error from catalina.out is:
"ERROR [TP-Processor40] - Servlet.service() for servlet jsp threw exception
javax.servlet.jsp.JspException: Define tag cannot set a null value
at org.apache.struts.taglib.bean.DefineTag.doEndTag(DefineTag.java:272)
etc. etc."
if i comment this line "request.setAttribute("limitNewsList" ,
limitNewsList );", the page is shown without errors.
