David/Dave,
How are you going with this? I'm currently trying to get my head around
it, and am having a real struggle with the relationship stuff in
jbosscmp. I've bought Dain's doco in the hope that would clarify things,
but my real problem is that I haven't used cmp2's relationships, so
playing catch up there. atm the jbosscmp seems to generate something
like:
<ejb-relation>
<ejb-relation-name>language-languagecode</ejb-relation-name>
<foreign-key-mapping>
<ejb-relationship-role>
<ejb-relationship-role-name>one-language-has-one-languagecode</ejb-relationship-role-name>
<fk-constraint>true</fk-constraint>
<foreign-key-fields>
<foreign-key-field>
<field-name>language</field-name>
<column-name>languageCode</column-name>
</foreign-key-field>
</foreign-key-fields>
</ejb-relationship-role>
</foreign-key-mapping>
<foreign-key-mapping>
<ejb-relationship-role>
<ejb-relationship-role-name>one-languagecode-has-one-language</ejb-relationship-role-name>
<fk-constraint>true</fk-constraint>
<foreign-key-fields>
<foreign-key-field>
<field-name>languageCode</field-name>
<column-name>language</column-name>
</foreign-key-field>
</foreign-key-fields>
</ejb-relationship-role>
</foreign-key-mapping>
</ejb-relation>
the problem being the presence of two <foreign-key-mapping> elements. The
DTD has:
<!ELEMENT ejb-relation (ejb-relation-name,
(foreign-key-mapping | table-mapping))>
anyway, I'm still looking through it, and will probably continue along
this road for a while. I had a fairly unsuccessful attempt of finding
previous conversations on this in the archives, so I suppose this email is
just trying to catch up with what is known to work, and what still needs
doing. As I see it, jbosscmp-jdbc.xml relationships needs work (although
I also gather the entire thing is optional from a jboss pov).
just re-read David's email below, which of course states exactly what I've
just said... so am wondering David if you (a) have made progress here, or
(b) could shoot me a sample of what the above _should_ look like, and I
can take it from there...
cheers
