JNDI Context lookup failure with jboss 3.2.3

benwang Apr 19, 2004 9:48 AM

Dear all,

Recently I tried to convert my program from websphere 5.1 to jboss 3.2.3, but I encountered jndi binding problem in the following statement :

Object homeObject = ctx.lookup("java:comp/env/ega/Login");
LoginHome loginHome = (LoginHome) javax.rmi.PortableRemoteObject.narrow(homeObject,LoginHome.class );
Login login = loginHome.create();

It always give me an error as follows :
10:15:37,516 INFO [STDOUT] NamingExceptionCould not dereference object
10:15:37,516 ERROR [STDERR] javax.naming.NamingException: Could not dereference
object. Root exception is
10:15:37,516 ERROR [STDERR] javax.naming.NameNotFoundException: ega not bound

Is there anybody kindly help me up , following is my web.xml, jboss-web.xml & jboss.xml for your reference :

I can't see any env-entry tags in your web.xml but only ejb-refs.
So, I suppose you should write
Object homeObject = ctx.lookup("java:comp/ejb/ega/Login");
instead of
Object homeObject = ctx.lookup("java:comp/env/ega/Login");

<ejb-ref>
<ejb-ref-name>ega/Login</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
com.ega.hd.HelpDeskEJB.LoginHome
com.ega.hd.HelpDeskEJB.Login
</ejb-ref>

Shouldnt the above be something like
<ejb-ref>
<ejb-ref-name>ega/Login</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
com.ega.hd.HelpDeskEJB.LoginHome
com.ega.hd.HelpDeskEJB.Login
</ejb-ref>

I added the home and remote tags. Is this how it is in ur ejb-jar.xml, Im not sure how it wud have deployed given the way you specified in the original post!
Can yu change it like this(if its not already) and try , deploy and run
