    Hibernate and Datasource properties

    joe_the_quick Newbie

      hi there,

      I want to use an Oracle XADatasource with Hibernate and tried this by using:
      hibernate.connection.datasource java:/XAOracleDS

      instead of:
      hibernate.connection.username user
      hibernate.connection.password pwd
      hibernate.connection.url jdbc:oracle:oci8:@mysid

      However, it seems that the PreparedStatements used by Hibernate are no longer of type OraclePreparedStatement which I need to set a parameter for correct Unicode-Support (oraprepstmt.setFormOfUse for NCHAR).

      How can I tell the Datasource Configuration in JBoss (oracle-xa-ds.xml) to retain the correct classes of OraclePreparedStatement used by the Oracle driver (oracle.jdbc.driver.OracleDriver).

      My current (working) Jboss Oracle XADatasource config:

      <xa-datasource>
       <jndi-name>XAOracleDS</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:oci8:@mysid</xa-datasource-property>
       <xa-datasource-property name="User">user</xa-datasource-property>
       <xa-datasource-property name="Password">pwd</xa-datasource-property>
       <!-- Uses the pingDatabase method to check a connection is still valid before handing it out from the pool -->
       <!--valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name-->
       <!-- Checks the Oracle error codes and messages for fatal errors -->
       <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
       <!-- Oracles XA datasource cannot reuse a connection outside a transaction once enlisted in a global transaction and vice-versa -->
       <no-tx-separate-pools/>
       </xa-datasource>


      thanks a lot
