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
