    nur niza Newbie

      hi,

       

      i have a problem on my coding.

       

      i have set my jbpm.cfg.xml as below:

       

      <service name="persistence">

        <factory>

        <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory">

        <field name="isTransactionEnabled"><false /></field>

        <!-- <field name="isCurrentSessionEnabled"><true /></field>

      <field name="sessionFactoryJndiName">

                  <string value="jndi/cms/SessionFactory" />

                </field> --> 

        </bean>

        </factory>

        </service>

       

      but still get the error:

       

      javax.servlet.ServletException: javax.servlet.ServletException: org.jbpm.JbpmException: couldn't get task instance '465986'

      Can anyone tell me what could be the cause?

       

      I've searched the forum and try the solution but the error still there.

       

      thanks.
