That said, the above dint work for a trivial example for me. Can you verify this as well? (Or am i reading the spec wrong ?)

Is the following code the correct way to retrieve the taskinstances for the specific tasknode name and task name? | private java.util.List getTaskInstance(String tasknodename, String taskname) throws Exception { | log.debug("getTaskInstance() is called"); | log.debug("" + ctx.getCallerPrincipal().getName()); | JbpmConfiguration config = null; | JbpmContext jbpmContext = null; | java.util.List list = null; | java.util.List list2 = new ArrayList(); | try { | InitialContext ic = new InitialContext(); | config = (JbpmConfiguration) ic | .lookup("java:/jbpm/JbpmConfiguration"); | jbpmContext = config.createJbpmContext(); | list = jbpmContext.getTaskMgmtSession().findPooledTaskInstances(ctx.getCallerPrincipal().getName()); | for(Iterator iter=list.iterator();iter.hasNext();){ | TaskInstance taskinstance =(TaskInstance) iter.next(); | Task task = taskinstance.getTask(); | if(task.getName()!=null &&task.getName().equals(taskname) && task.getTaskNode().getName().equals(tasknodename)){ | list2.add(taskinstance); | } | } | log.debug("return task instance set size ="+list2.size()); | } finally { | if (jbpmContext != null) | jbpmContext.close(); | } | return list2; | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3964829#3964829 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3964829

>From the EJB Spec, anonymous wrote : | A persistence unit must have a name. Only one persistence unit of any given name may be defined within a single EJB-JAR file, within a single WAR file, within a single application client jar, or within an EAR (in the EAR root or lib directory). | And as for scope of the persistence.xml (between EJB, WEB, or EAR) anonymous wrote : | A persistence unit that is defined at the level of the EAR is generally visible to all components in the application. | So if you put your generic persistence.xml in the root folder(where your EAR is defined or in a lib subfolder), all your sub deployments should be able to use that.

by yxyang

got it. hibernate.queries.hbm.xml file.... Although it is not difficult, if i want to use only EJBs 2 and not the hibernate code in my application code (i prefer to keep the hibernate stuff under the cover of the jbpm api)., it is no direct way.

[EJB 3.0] - Re: Can't find branch for FD8 release, posted documentation

by raja05

Welcome to frustration while searching code. Ive tried this before and am still not very comfortable at locating branches and source codes to attach to Idea. Anyway , here are some answers that might help. "gcomnz" wrote : | 1. The EJB 3.0 releases don't contain source, making it difficult to attach source in IDEs for debugging | The EJB3.0 sources are part of the JBoss_4_0 branch and can be obtained here https://svn.jboss.org/repos/jbossas/branches/Branch_4_0/ The subtrees are ejb3 and ejb3x "gcomnz" wrote : | 2. I've been searching for a long time in the CVS repository and can't seem to find the version tag for releases, meaning that I can't find the accurate sources for what I'm using in order to get around problem 1 | These got shifted to SVN sometime late July I think and SVN seems to be more easier to navigate( Fisheye sucks if you dont know the branch or tag names). Also, Fisheye does not seem to have any tag information, so unless you know the tag for a subtree, you are lost. Anyway, if you are able to find out the tag/branch names from any of the commit messages, here is how to do the browsing for a particular tree fisheye.labs.jboss.com/viewrep/~tag=JBoss_Seam_1_0_1_GA/JBoss/jboss-seam That would fetch the JBoss_Seam_1_0_1_GA tag for Seam and I got the tagname from one of the commit messages.

[JBoss jBPM] - Re: The process class loader issue

by yxyang

I already achieve what i want to do. Actually, there is no problem for the jboss software itself. THe problem is more on the confusion of how to use the jboss components when classloader involves. TO make the classes in .par file be able to access the class in ejbs, make sure the two parts use the same classloader. yang View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3964825#3964825 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3964825
