    JBossCmp and Custom Finders

    Charles Newbie

      (This was sent as a reply to Jboss 3.0 Alpha and Custom Finders but doesn't seem to want to post, so I'm submitting it as a new topic)

      I'm getting the following deployment error from JBoss for my ejbql. Have looked at examples as well as spec, and don't really see what JBoss (3.0.4) doesn't like about it.

      Any suggestions will be greatly appreciated!

      Error from JBoss:

          In the query part of or @ejb:finder you need the abstract-schema-name not your table name. The abstract-schema-name (see your ejb-jar.xml file) is set by xdoclet. It uses the name attribute of your @ejb:bean tag. So the correct query part would be:
          SELECT OBJECT(u) FROM test/TWUserRole AS u WHERE u.USER_USERID = ?1
          I'm not sure if you can use a "/" their but give it a try.
          But I think it would be better if you also change the name attribute to a value without "/" :-)

            Thanks - you are correct. By using the bean name and the field names found in <field-name> in the jbosscmp-jdbc.xml I resolved the problem.
