Hello,

I'm using JBoss 5.1.0.GA, jdk 1.6, on Linux

I wanted to use the Oracle DB for messaging, so I started like this:
- created a new schema in Oracle
- creating a new oracle-xa-ds.xml file, using <xa-datasource> (we use distributed transaction because we write into another Oracle DB, while   adding to a Queue)
- copied from JBOSS_HOME/docs/examples/jms/oracle-persistence-service.xml to xxx/deploy/messaging/oracle-persistence-service.xml.
- replaced DefaultDS with MyOracleDS in all 3 places
- deleted xxx/deploy/messaging/hsqldb-persistence-service.xml

When starting JBoss, the error was:
=> java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist

After adding in jboss-log4j.xml

   <category name="org.jboss.messaging">
      <priority value="DEBUG"/>
   </category>

=> CREATE TABLE JBM_MSG (MESSAGE_ID INTEGER, RELIABLE CHAR(1), EXPIRATION INTEGER, TIMESTAMP INTEGER, PRIORITY INTEGER, TYPE INTEGER, HEADERS BLOB, PAYLOAD BLOB, PRIMARY KEY (MESSAGE_ID))
java.sql.SQLSyntaxErrorException: ORA-02089: COMMIT is not allowed in a subordinate session

So, what I did was to replace <xa-datasource> with <local-datasource>, and it worked fine: all tables were added to the Oracle schema.
Afterwords, I put all "CreateTablesOnStartup" to false oracle-persistence-service.xml and put back <xa-datasource>.

I did a test, and it adds messages successfully to the Oracle DB.
