    Oracle 10g with Jboss 4.2.3 Entity Manager / Hibernate

      My application uses 3 different datasources all going to the same database. One with XA support is used via the JNDI name by the entity manager configured in persistence.xml. The other two are no-tx-datasources.

      I am able to access certain aspects using the datasources however as soon as I try to make a change via entity manager I get the error shown below.

      Any suggestions on what I am doing wrong. The same application works fine using SQL Server 2005.

          XA-connections seem to be very complicated. It took us some time to find the right settings.
          What's the content of XA-Datasource description?
          Ours is

          <?xml version="1.0" encoding="UTF-8"?>
<datasources>
 <xa-datasource>
 <jndi-name>ora-11g</jndi-name>
 <track-connection-by-tx/>
 <isSameRM-override-value>false</isSameRM-override-value>
 <xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
 <xa-datasource-property name="URL">jdbc:oracle:thin:@sb2000:1521:11g</xa-datasource-property>
 <xa-datasource-property name="User">lafr</xa-datasource-property>
 <xa-datasource-property name="Password">...</xa-datasource-property>
 <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name>
 <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
 <prepared-statement-cache-size>100</prepared-statement-cache-size>
 <metadata>
 <type-mapping>Oracle9i</type-mapping>
 </metadata>
 </xa-datasource>
</datasources>
