j2sdk 1.4.1_02
JBoss w/ Tomcat 3.2.1
Red Hat 8
I tried poking around around the archives, but there's no search feature (at
least that I could find) so please excuse me if this has been covered
somewhere else.
I'm trying to create a simple CMR to see if I can get it working but I've hit
sort of a road block. The two beans work just fine by themselves but if I try
a one-to-one relationship it dies a horrible exception death. All I'm trying
to do is do a get on the CMR object that is contained by the main bean. The
exception that is on the top of the stack is:
ERROR [STDERR] javax.ejb.EJBException: null; CausedByException is: null
The only thing I am doing is Country newCountry = getCountry();
As in all my problems getting things to work, I believe it is with my
deployment descriptors. I've looked in the O'Reilly book as well as Mastering
EJB's and the JBoss Documentation but I'm not seeing what I'm doing wrong.
Thanks in advance,
Andy
Here's a snippet from ejb-jar.xml
<ejb-jar>
...
<relationships>
<ejb-relation>
<ejb-relation-name>Invoice-Country</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>invoice-has-country</ejb-relationship-role-name>
<multiplicity>One</multiplicity>
<relationship-role-source>
<ejb-name>InvoiceEJB</ejb-name>
</relationship-role-source>
<cmr-field>
<cmr-field-name>Country</cmr-field-name>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>country-belongs-to-an-invoice</ejb-relationship-role-name>
<multiplicity>One</multiplicity>
<relationship-role-source>
<ejb-name>CountryEJB</ejb-name>
</relationship-role-source>
</ejb-relationship-role>
</ejb-relation>
</relationships>
...
</ejb-jar>
And the cooresponding info in jbosscmp-jdbc.xml:
<jbosscmp-jdbc>
...
<relationships>

<read-only>false</read-only>
<foreign-key-mapping/>

<ejb-relationship-role-name>invoice-has-country</ejb-relationship-role-name>
<key-fields/>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>country-belongs-to-an-invoice</ejb-relationship-role-name>
<key-fields>
<key-field>
<field-name>ID</field-name>
<column-name>country_id</column-name>
</key-field>
</key-fields>
