Summary: jbosscmp-jdbc.xml problem
Initial Comment:
When the <ejb-relationship-role> tag is included in
jbosscmp-jdbc.xml an exception is thrown when a
bean is added to a relation.
The exception is:
03:18:41,539 ERROR [GlobalTxEntityMap] Store failed
on entity: 1
javax.ejb.EJBException: Could insert relations into
ABean_b_BBean_a

03:18:41,565 INFO [STDOUT] 1:ROLLBACK
I've attached a testcase that can be deployed in
Jboss and run as a client using: java -jar
beans-ejb.jar nl.paardenmarkt.ejb.Test.
The testcase as attached works, but when the
lower-halve of jbosscmp-jdbc is included (by
removing the comments) it will not run. This code is
generated with XDoclet, so it might be a problem with
their template.
This is on RH3.0 CVS 26 feb. 2002

I added code to throw a Deployment exception if neither
side of a foreign-key mapped relationship has keys or if
either side of a relation-table mapped relationship doesn't
have keys.

In your jbosscmp-jdbc.xml file you have the following:
<relationships>
<ejb-relation>
<ejb-relation-name>ABeanB</ejb-relation-name>
<foreign-key-mapping/>
<!--
<ejb-relationship-role>
<ejb-relationship-role-name>A-has-B</ejb-
relationship-role-name>
<key-fields/>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>B-belongs_to-A</ejb-
relationship-role-name>
<key-fields/>
</ejb-relationship-role>
-->
</ejb-relation>
</relationships>
Notice that both "key-fields" elements are empty. By doing
this you are telling the store manager that neither side of
the relationship will have foreign keys.
I will try to add some code to throw a deployment exception
in this case. In the mean time, add some keys to atleast
one side of the relationship.

I've just committed a test case that happens to demonstrate
this problem.
org.jboss.test.cmp2.cmr.test.CMRPostCreatesWrittenUnitTestCase
This test uses xdoclet also, and works fine if you remove
the relationships element from the generated
jbosscmp-jdbc.xml, but fails when it is present.
