XA connection problem

Hi,

I'm working on carrying out application on Oracle database to PostgreSQL.

The server is weblogic.
For Oracle we use XA connection but there isn't in PostgreSQL so I try to use XA emulate Connection taht allows
weblogic.But I don't succeed to use it correctly. 
The connection seems correct, but at a time, the server uses the method getXAResource() and this method return null and
anerror is produced. 

I've checked the case "Emulate XA connection" on my weblogic server connection.

When i create my connection I do,

Connection cx = getPostgresqlDataSource().getConnection();
return new ManagedConnectionImpl(this, pwdCred, null, cx, false, false);

and getPostgresqlDataSource is :
private javax.sql.DataSource getPostgresqlDataSource() throws ResourceException
  {
    try
    {
      InitialContext initialContext = new InitialContext();
      return (javax.sql.DataSource)initialContext.lookup(ADOCProperties.getKeyValue(ADOCProperties.
          FRAMEWORK_XA_DATASOURCE_DRIVER));
    }
    catch (Exception e)
    {
      logger.severe(e.getMessage());
      return null;
    }
  }


Is somebody have an idea ?
