[JBoss Seam] - NPE with component's entity-query
by trouby
Hey,
With Seam ver 1.2 I used <framework:entity-query> a lot and it worked perfectly,
After migrating to Seam v2, I get a NPE exception,
I have a persistence managed context declared in components.xml as:
| <core:managed-persistence-context name="entityManager" auto-create="true" persistence-unit-jndi-name="java:comp/env/edm_acc_em"/>
|
where in web.xml I have a 'persistence-unit-ref' reference,
Please note that I am using Glassfish V2 as an Appserver.
Following is a part of the NPE stuck trace:
| Caused by: java.lang.NullPointerException
| at org.jboss.seam.framework.EntityQuery.createQuery(EntityQuery.java:140)

Thanks,
Asaf.

[JBoss Seam] - Seam 2.0 beta problem
by Kruno
I started to migrate from seam 1.21 to 2.0 (jboss 4.2), I followed migration tutorial, and examples in seam 2.0.
The problem is when I try to call some bean with ajax4jsf component or tomahawk component I get exception, but with h:commandButton or s:button
things work.
Thanks in advance for any help Kruno.

[JBoss Messaging] - Re: PingTimerTask broken pipe
by bob_walker99
Update:
I've just tried restarting the server and resubmitting one of my client jobs - whilst it is running , the client has many, many threads created seemingly in pairs like this:
Timer-7 (main), 5, alive, daemon
control: Socket[addr=/10.0.x.xx,port=3089,localport=37979] (main), 5, alive, daemon
Each pair has an incremented [Timer-nnn] number, and a different value for ["localport"].
Regards,
Bob
