[jboss-user] [JBoss jBPM] - saving own objects with Hibernate in jbpm

Hi all, I have custom objects that I have added to the jbpm schema. Those objects are hibernatable. My app is multithreaded. What is the prefered way to save the custom objects ? When I get the hibernate session from a newly created jbpmcontext, I get an exception like this org.jbpm.JbpmException: closed JbpmContext in different order then they were created... check your t | ry-finally's around JbpmContexts blocks Using something like this in my main class , | public static synchronized JbpmContext getPersistenceContext() { | if(JbpmContext.getCurrentJbpmContext()!=null) | return JbpmContext.getCurrentJbpmContext(); | else | return instanceConfigurationJbpm.createJbpmContext() ; | } | , I get an NPE on a Criteria.list() call based on a Session obtained via getPersistenceContexte().getSession java.lang.NullPointerException | at org.hibernate.jdbc.AbstractBatcher.getPreparedStatement(AbstractBatcher.java:442) | at org.hibernate.jdbc.AbstractBatcher.getPreparedStatement(AbstractBatcher.java:368) | at org.hibernate.jdbc.AbstractBatcher.prepareQueryStatement(AbstractBatcher.java:105) | at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1561) | at org.hibernate.loader.Loader.doQuery(Loader.java:661) | at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:224) | at org.hibernate.loader.Loader.doList(Loader.java:2150) | at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2029) | at org.hibernate.loader.Loader.list(Loader.java:2024) | at org.hibernate.loader.criteria.CriteriaLoader.list(CriteriaLoader.java:94) | at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1492) | at org.hibernate.impl.CriteriaImpl.list(CriteriaImpl.java:298) | ...... | What is the best practise to save one's own objects ?
