partly beans Not Bound

[ray frid]

Hi all,
I am migrating Jboss 4 to Jboss 5.1AS.

There is some weird situation where part of my Stateless beans are not bounded.

this is the Exception as you all know it:

18:38:30,046 ERROR [STDERR] javax.naming.NameNotFoundException: LogDaoBean not bound
18:38:30,046 ERROR [STDERR] at org.jnp.server.NamingServer.getBinding(NamingServer.java:771)
18:38:30,046 ERROR [STDERR] at org.jnp.server.NamingServer.getBinding(NamingServer.java:779)

If we look at the server log we can find this error

DEPLOYMENTS IN ERROR:
Deployment "<UNKNOWN jboss.j2ee:ear=WMA_EXPLODED.ear,jar=WMA_EXPLODEDEJB.jar,name=LogDaoBean,service=EJB3>" is in error due to the following reason(s): ** UNRESOLVED Demands 'persistence.unit:unitName=WMA_EXPLODED.ear/WMA_EXPLODEDEJB.jar#wmaPU' **



Any idea what could cause it?

thanks,

ray.
