JBPM Persistence Error
khalipili Jan 12, 2011 3:05 PMNeed help in persisting entire workflow in MySql database.
I have created a sample workflow in JBPM and trying to persist the flow in MySQL database. JBPM is successfully starting the process and start persisting the session info. but once it comes to persist "Human Task" it throws error message as - "java.lang.IllegalArgumentException: Unknown entity: org.drools.persistence.processinstance.WorkItemInfo"
My persistence.xml file config is :
<persistence-unit name="org.jbpm.persistence.jpa" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>jdbc/processInstanceDS</jta-data-source>
<class>org.drools.persistence.session.SessionInfo</class>
<class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>
<class>org.jbpm.persistence.processinstance.ProcessInstanceEventInfo</class>
<properties>
<!-- MySQL database -->
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/TaskDB" />
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
<property name="hibernate.connection.username" value="root" />
<property name="hibernate.connection.password" value="password" />
<property name="hibernate.max_fetch_depth" value="3" />
<property name="hibernate.hbm2ddl.auto" value="update" />
<property name="hibernate.show_sql" value="true" />
<!--
<property name="hibernate.jndi.class" value="bitronix.tm.jndi.BitronixInitialContextFactory" />
-->
<property name="hibernate.transaction.manager_lookup_class"
value="org.hibernate.transaction.BTMTransactionManagerLookup" />
</properties>
</persistence-unit>
I am using JBPM5 - 5.0-SNAPSHOT Build
additional issue in JBPM persistence - if you have a Rule Task in workflow, rule task is getting executed but it throws below error
"java.lang.IllegalArgumentException: Named query not found: ProcessInstancesWaitingForEvent".
Please guide me to resolve these issues.
