EJB Sample Question

Question

Hi there,
My questions here referred to WebLogic server 6.1 examples.ejb20.basic.statelessSession
and I m yet not attended any J2EE classes yet.
1. What does the method ejbPassivate() and setSessionContext(SessionContext ctx)
invoked inside TraderBean class does? Since I can't find any codes called the setSessionContext
that needs a input parameter?
2. Under ejbCreate(), the line statd Integer tl = (Integer) ic.lookup("java:/comp/env/tradeLimit");,
where do i get java:/comp/env/tradeLimit? Is that stated inside the ejb-jar.xml under
the entry <env-entry>?
3. Can explain what are the steps invoked inside the build.xml after compiling the
class files?
4. What does the weblogic-ejb-jar.xml does?
Thanks
Neo

For 1 & 2 You need to read a EJB Book. There is a free one available at
www.theserverside.com.
for 4, look at
