[JBoss jBPM] - Re: how list all tasks?
by simonbaker
Unfortunately wild card doesn't work because the query in "hibernate.queries.hbm.xml" is:
| <query name="TaskMgmtSession.findTaskInstancesByActorId">
| <![CDATA[
| select ti
| from org.jbpm.taskmgmt.exe.TaskInstance as ti
| where ti.actorId = :actorId
| and ti.isSuspended != true
| and ti.isOpen = true
| ]]>
| </query>
|
I tried changing the anonymous wrote : where ti.actorId = :actorId to anonymous wrote : where ti.actorId like :actorId in the "hibernate.queries.hbm.xml" file embedded in the "jbpm-jpdl.jar", and then the wildcard worked (using an Oracle9 connection, by the way).
List taskList = jbpmContext.getTaskList("%");
Again, making a custom jBPM library is a maintenance worry. I hope the developers will give us an API for getting the complete task list. Our need is to be able to filter the complete list by various groups of users or other criteria.

[Installation, Configuration & DEPLOYMENT] - ClassNotFoundException when using annotations
by goldrimtang
Hello forums,
I am porting an application form Jboss 3.2.6 to 4.2.1. After some minor tweaks, the application runs well. Then, I want to start taking advantage of new features, such as the usage of annotations instead of xdolcet.
I started with just one stateless session bean, removing the xdoclet comments and replacing them by @Stateless, etc.
The next deploymnet I get :
Caused by: java.lang.ClassNotFoundException: No ClassLoaders found for: com.xxx.xxx.xxx.MyClass[]
(see the complete stack trace below).
The class not being found has nothing to do with the statless session bean being converted. Even more, if I just remove the stateless session bean from the jar file, it goes back to deploying everything well.
The application is an EAR file, with a WAR file, a JAR file from common classes, and a JAR file with the EJBs (three total). Again, if left alone without any annotated classes, it works well.
This looks like a classloading problem. After much searching and wiki-reading, I didn't go any further. My question is, what impact does it have in the class loading process to have one class annotated? Is is OK to mix old-style ejbs (2.x) with new ones (EJB 3)?.
Thanks very much for any help or clue on how to solve this!!
