hi, all
i followed the Tutorial doc 1.5 in detail but got failure

javax.servlet.ServletException: Lookup of java:comp/env/ejb/Fibo faild
 at tutorial.web.ComputeServlet.init(ComputeServlet.java:58)
 at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1105)

 at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:17
 at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociation
va:175)

Here is my environment:
jdk1.5.0_10
Eclipse3.2
IDE2.0.0 Beta2
JBoss 4.0.5GA

I didnot creat FiboEJB-client.jar and it must not be the problem of duplicated interfaces in war and jar. And i have also tried with

java:env/ejb/Fibo

and

ejb/Fibo

But still failed.

Can anyone help me?

thanks!
