[jboss-user] [JBoss jBPM] - problem persisting jBPM process instance
Hi guys,
I have a problem persisting a process instance using hibernate. Here is the scenario:
- I had a project based on jBPM, created on seam 4.0; when persisting a process instance
there were no problems
- in the meantime I changed the project structure to work on seam 4.2; and now I get error
when persisting the process instance; below is the error:
12:35:10,017 ERROR [STDERR] org.hibernate.MappingException: An AnnotationConfiguration
instance is required to use <mapping
class="ro.fii.projectmanager.model.Flow"/>
| at
org.hibernate.cfg.Configuration.parseMappingElement(Configuration.java:1600)
| ...
and here is the code that is used to persist the process instance:
JbpmConfiguration jbpmConfig = null;
| JbpmContext jbpmContext = null;
| try {
| jbpmConfig = JbpmConfiguration.getInstance();
| jbpmContext = jbpmConfig.createJbpmContext();
| ProcessDefinition pd = ProcessDefinition.parseXmlString(
| "<process-definition name=\"pd-name\">"
+
| " <start-state>" +
| " <transition to='s' />" +
| " </start-state>" +
| " <state name='s'>" +
| " <transition to='end' />" +
| " </state>" +
| " <end-state name='end' />" +
| "</process-definition>");
| ProcessInstance processInstance = new ProcessInstance(pd);
| jbpmContext.save(processInstance);
| }
| catch(Exception e) {
| e.printStackTrace();
| }
| finally {
| if (jbpmContext!=null) {
| jbpmContext.close();
| }
| }
Even stranger is that when I comment my classes from hibernate.cfg.xml and then try to
persist again the process definition I don't get any errors, but the first time it
wants to persist the process instance, all the classes from hibernate.cfg.xml are
re-mapped and then the process instance is saved.
I don't know exactly what to ask from you. If anyone has any suggestion they are more
than welcomed. Thanks!
Alex
