      I verified the hibernate.properties. it contains,

      hibernate.dialect=org.hibernate.dialect.HSQLDialect


      also the hibernate.cfg.xml contains

      <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>



      Can anyone help me to resolve the above issue.

      Thanks,
      Anamica

            wrong forum, this has nothing to do with jBPM, try e.g. the JBoss AS forum
