Hi,
I installed for the first time jBPM 5.3 on Tomcat with Oracle 10g, and with this
installation I created database schema on my Oracle schema.
Then I installed on my Eclipse plugin to create a new jBPM project a to use designer. Then
i'd like to try it with this sample:
https://community.jboss.org/people/bpmn2user/blog/2011/03/25/jbpm5--persi...
https://community.jboss.org/people/bpmn2user/blog/2011/03/25/jbpm5--persi...
I've two problems executing it, one in orm.xml file, one creating KnowledgeSession.
The orm.xml file seems not updated, in fact i modify it in two parts (number of arguments
of TaskSummary, escalated in Deadline is not boolean), however i've this error:
652 05/07 17:04:02,498[main] ERROR
hibernate.impl.SessionFactoryImpl.<init> - Error in named query:
ProcessInstancesWaitingForEvent
org.hibernate.hql.ast.QuerySyntaxException: ProcessInstanceInfo is not mapped [select
processInstanceInfo.processInstanceId from ProcessInstanceInfo processInstanceInfo where
:type in elements(processInstanceInfo.eventTypes)]
I've the error on this named-query:
<named-query name="ProcessInstancesWaitingForEvent">
<query>
select
processInstanceInfo.processInstanceId
from
ProcessInstanceInfo processInstanceInfo
where
:type in elements(processInstanceInfo.eventTypes)
</query>
</named-query>
If i delete this named-query the initialization seems to go, but i've this other
error:
Hibernate: select SESSIONINFO_ID_SEQ.nextval from dual
843 05/07 15:15:24,278[main] ERROR hibernate.util.JDBCExceptionReporter.logExceptions -

at com.sample.ProcessTestTask.main(ProcessTestTask.java:114)
I don't understand why ProcessInstanceInfo seems to be not mapped and also why a
sequence can do this error.
Can you help me, please?

Make sure you have proper definitions in your persistence xml, here is a sample from
default installation (not complete just the relevant part, I think):
<persistence-unit name="org.jbpm.persistence.jpa"
transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:jboss/datasources/jbpmDS</jta-data-source>
<mapping-file>META-INF/JBPMorm.xml</mapping-file>
<mapping-file>META-INF/ProcessInstanceInfo.hbm.xml</mapping-file>
<class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>
<class>org.drools.persistence.info.SessionInfo</class>
<class>org.drools.persistence.info.WorkItemInfo</class>
<class>org.jbpm.process.audit.ProcessInstanceLog</class>
<class>org.jbpm.process.audit.NodeInstanceLog</class>
<class>org.jbpm.process.audit.VariableInstanceLog</class>
Important element is in bold, make sure you have it there and it is accessible as that
file defines ProcessInstanceInfor entity. This is valid for hibernat 3.x usage (JPA1).
