[jboss-user] [JBoss Seam] - Problem on listTimerHandles

[quintenjiang]

My error message like at Jboss 4.2.0 + Seam 1.3:

[org.jboss.ejb3.stateless.StatelessDelegateWrapper] Starting failed jboss.j2ee:ear=jboss-seam-booking.ear,jar=jboss-seam.jar,name=TimerServiceDispatcher,service=EJB3
java.lang.NullPointerException
	at org.jboss.ejb.txtimer.DatabasePersistencePolicy.listTimerHandles(DatabasePersistencePolicy.java:165)
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

I use Mysql DB. In the previous version 4.0.3. I put mysql-ds.xml and remove hsqldb-ds.xml. It work fine with DB.

Then I use Seam and use Jems to install Jboss 4.0.5. It use GUI to configure DB connection and put it on the file hsqldb-ds.xml. even I use MySQL. But I work fine.

After that  I try to use Jboss-4.2..0*, and use hsqldb-ds.xml or mysql-ds.xml to configure MySQL connection. I got same problems
(JBoss + Seam 1.3, and seam booking)

Can anyone help me on this?

Thanks,


Quinten
