Hello,
In a method of a stateless EJB3 I deployed the hello world process (of
StarterKit) in a MySQL database, then manage to create an instance for it.
Later in another function, I try to create a process instance with those 2
instructions
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
| ProcessInstance processInstance =
jbpmContext.newProcessInstance("test");
I then obtain the following exception :
| javax.ejb.EJBException: org.hibernate.HibernateException: null index column
for collection: org.jbpm.graph.def.ProcessDefinition.definitions
| at
org.jboss.ejb3.tx.Ejb3TxPolicy.handleExceptionInOurTx(Ejb3TxPolicy.java:69)
| ...
| ...
| at org.hibernate.collection.PersistentMap.values(PersistentMap.java:198)
| at
org.jbpm.graph.exe.ProcessInstance.<init>(ProcessInstance.java:103)
| at org.jbpm.JbpmContext.newProcessInstance(JbpmContext.java:371)
| ...
|
I tried several process with no success... and can't figure out where is the
problem.
My config : WinXP/JBoss4.0.4GA/JBPM3.1/MySQL
jbpm.cfg.xml :
| <jbpm-configuration>
| <jbpm-context>
| <service name="persistence">
| <factory>
| <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory">
| <field name="isTransactionEnabled"><false /></field>
| </bean>
| </factory>
| </service>
| <service name='message'
factory='org.jbpm.msg.db.DbMessageServiceFactory' />
| <service name='scheduler'
factory='org.jbpm.scheduler.db.DbSchedulerServiceFactory' />
| <service name='logging'
factory='org.jbpm.logging.db.DbLoggingServiceFactory' />
| <service name='authentication'
factory='org.jbpm.security.authentication.DefaultAuthenticationServiceFactory'
/>
| </jbpm-context>
| </jbpm-configuration>
|
For Hibernate I tried both MySQLDialect and MySQLInnoDBDialect
Thanks in advance,
Sebastien
