JNDI lookup error when injecting a stateful bean into a stateful bean
in glassfish
----------------------------------------------------------------------------------
Key: JBSEAM-2430
URL:
http://jira.jboss.com/jira/browse/JBSEAM-2430
Project: JBoss Seam
Issue Type: Bug
Components: EJB3, Platform interoperability
Reporter: Richard Hoffman
Per Pete's request
(
http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4115521#...) I'm
making a ticket about the problem I'm facing:
Using glassfish, I'm trying to inject a stateful bean into a stateful bean...instead
of describing my specific app and trying to explain exactly what I'm doing and why, I
figured I'd demonstrate how to duplicate my problem using the jee5/booking example
provided with Seam 2:
1.) Add the following to the top of HotelSearchingAction:
import org.jboss.seam.annotations.In;
.
.
@In(create=true)
private HotelBooking hotelBooking;
2.) Redeploy and run the booking app.
3.) Navigate to the Search page. You should receive a "Could not instantiate Seam
component: hotelBooking" error, which is caused by:
"javax.naming.NameNotFoundException: No object bound to name
java:comp/env/jboss-seam-jee5/HotelBookingAction/local"
Now, granted, in this particular case, there really isn't any functional reason to do
this injection, but it demonstrates the same problem I'm having on my particular
application (where this kind of injection makes sense). It is also worth noting that if
you do the opposite injection (HotelSearching into HotelBookingAction), you have no
problems.
One way I found to get around this problem is to put a @Startup at the top of the
HotelBookingAction bean, but I'm not sure why this is necessary.
---
My theory as to what's going on is as follows...my apologies if I'm way off,
heh:
The page flow of the booking app is Login -> Search (which uses HotelSearchingAction)
-> Book Hotel (which uses HotelBookingAction). So, HotelSearchingAction gets
(instantiated?) put in the JNDI tree first, as the user progresses through the app. The
problem is, when you inject HotelBookingAction into HotelSearchingAction,
HotelBookingAction needs to be created when HotelSearchingAction is first used, but it
hasn't been put in the JNDI tree yet, so we get a lookup error. And of course, if you
put @Startup on HotelBookingAction, HotelBookingAction is now in the JNDI tree way before
HotelSearchingAction needs it, so the error is gone. But again, I'm not sure why
@Startup should be necessary to inject a not-yet-used stateful bean into a stateful bean.
Thanks in advance to anyone who works on this ticket. :-)
