a CMP problem under jb+wls,struts.....

deploy on jbuilder+weblogic+struts:
i built a project(named untitled2):
creat a CMP(name as News);
creat a webapplication(name

aperapp) with struts framework;
creat Action(name

aperaction), a part of which source is follow:
javax.naming.Context context = new javax.naming.InitialContext();
context.lookup("untitled2.NewsHome");//I think that " untitled2.NewsHome " is wrong .but what is right,help me!!!

by the way:
the deploy and run is all right,but the follow errors:
javax.naming.LinkException: . Root exception is javax.naming.NameNotFoundException: While trying to look up /app/ejb/News.jar#News/local-home in /app/webapp/paperapp/26723714.; remaining name '/app/ejb/News/jar#News/local-home'
