    Hibernate config problem

    Martin Ehrlich Newbie

      Hi,

      we are using the jBPM-Starters-Kit. jBPM is configured to use an Oracle 9DB. Everything works fine using the JBoss-DataSource JbpmDS.

      All our ActionHandlers and depending classes come in their own war file. The classes already use a JNDI datasource-pool named vsab. They are calling PL/SQL stored procedures for read. Everything works fine.

      To start a jBPM-process we use our own WebService-Classes via XFire.

      We want to persist some of our objects in the db with Hibernate. In our war-file we put an hibernate.cfg.xml. The classes got their own hbm.xml.

      Our hibernate.cfg.xml looks like:

      <?xml version='1.0' encoding='utf-8'?>
      <!DOCTYPE hibernate-configuration PUBLIC
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
      "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

      <hibernate-configuration>

      <session-factory>

      <!-- Database connection settings -->
      org.hibernate.dialect.Oracle9Dialect
      java:/vsab




      </session-factory>

      </hibernate-configuration>

      But when I start a process when this hibernate.cfg.xml is present in our war-File we get the following:

      .....

      It seems es if the Hibernate-configs clash so that jBPM doesn't find it's own Hibernate config.

      How do I have to configure it? "It" standing for "jBPM" or for our own application or for something completely different? ;-)

      Thanks,
      Martin
