I have the similar problem with hibernate323, jbpm321, jboss420.

The strange thing is if I use ejb timers to execute all the fork steps,
everything is fine. However, if driving one of the fork steps with external
jbpmconfigure, although still using the same hibernate session factory as other
timers steps, it will have this error, my external jbpmconfig code looks like:
caller:
|
| public void doTranstion(long id, String tokenPath, String path) throws
Exception {
| JbpmContext jbpmContext =
JbpmUtil.getJbpmConfig().createJbpmContext();
| try {
| ProcessInstance processInstance =
jbpmContext.loadProcessInstanceForUpdate(id);
| if (processInstance == null) {
| logger.debug("ProcessInstance " + id + " does
not exist anymore. Ignore it");
| return;
| }
|
| Token token = processInstance.findToken(tokenPath);
| logger.info("ProcessIntance " + processInstance.getId()
+ " changing from node[" +
token.getNode().getDefaultLeavingTransition().getFrom().getName() + "] to
node["
| +
token.getNode().getDefaultLeavingTransition().getTo().getName() + "]" + ".
File=" + path);
| token.signal();
| } catch (Exception e) {
| logger.error("", e);
| throw e;
| } finally {
| jbpmContext.close();
| }
| }
|
|
|
| public class JbpmUtil {
| static Logger logger = Logger.getLogger(JbpmUtil.class);
| static private JbpmConfiguration jbpmConfiguration = null;
|
| synchronized static public JbpmConfiguration getJbpmConfig() {
| if (jbpmConfiguration == null) {
| jbpmConfiguration =
JbpmConfiguration.getInstance("jbpm.cfg.xml");
| }
|
| return jbpmConfiguration;
| }
| ...}
Using treecache with serializable isolation. Token used in the code is
retrieved from
ExecutionContext.getToken().getFullName();
Still wondering what is difference here? Should treecache take care this?
