Category: JBossCMP Group: None Status: Open Resolution: None Priority: 5 Submitted By: David Sills (davidsills) Assigned to: Nobody/Anonymous (nobody) Summary: Problem reading foreign-key datasource Initial Comment: Windows XP Professional JDK 1.4.2 JBoss 3.2.3 (but should be fixed in other versions as well) If the default datasource specified in standardjbosscmp- jdbc.xml is not deployed, foreign-key relationships throw an exception upon deployment (see stack trace in accompanying document). Why it happens and a suggested fix: When reading the jbosscmp-jdbc file in JDBCRelationMetaData, no datasource value can be retrieved for foreign-key relationships (since foreign-key is an empty tag, not having a "datasource" child), so the defaults in standardjbosscmp-jdbc.xml are used. The same is true for datasource mapping (Code excerpt 1). A test is performed in JDBCStartCommand that tries to retrieve the datasource for any kind of relationship (Code excerpt 2). This calls JDBCRelationMetaData. If the datasource does not exist (and there should not have to be a guaranteed DefaultDS or any other default datasource on a JBoss installation), JDBCRelationMetaData throws an Exception (Code excerpt 3). A logical fix is to have the JDBCRelationMetaData assign the datasource and datasource mapping for a foreign- key relationship from one of the entities involved in the relationship (which are retrievable from the JDBCRelationRoleMetaData) (Code excerpt 4). Since the datasource and datasourceMapping variables are final, this requires that they not be assigned where they are currently; the current assignments should be removed (Code excerpt 5 and 6). In this way, the datasource and datasource mapping values for foreign-key mappings will be as valid as they are for relation-table mappings. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=937974&group_id=22866 ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
