Please help: deploy Bean with "No resource available" error for M:N relationship

Question

Hi all,
I wonder any one comes across with deploying beans with M:N relationship with
"No resource available".
I defined the relationship in ejb-jar.xml and dbms in the
weblogic-cmp-rdbms-jar.xml, but when I deployed the beans I got
the following error

Hi Gaurav,
Other applications used the same the datasource, which I used for this application,
are running fine.
I think there is some bug in the wlserver 6.1 to create the join table. I think
it is the time I should ask the bea wlserver 6.1.
