[bittu.arvind]

I followed the tutorial http://www.netbeans.org/kb/55/ejb30-jboss.html and tried to implement the same.

But it's throwing an exception of the following type.



java.lang.RuntimeException: javax.naming.NameNotFoundException: NewsApp not bound
web.ListNews.lookupNewsEntityFacade(ListNews.java:95)
web.ListNews.processRequest(ListNews.java:47)
web.ListNews.doGet(ListNews.java:69)
javax.servlet.http.HttpServlet.service(HttpServlet.java:697)
javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96



may sny one please help me why it has occurred and how to clear it ?

I will be thankful for your kind support.
