[JBoss jBPM] - Deleting a Process Definition throws Exception

by dhanushgopinath

Hi, I am using jBPM 3.2 with jbpm bpel 1.1.1.GA. I am trying to delete a bpel process definition using the deleteProcessDefinition API on Grpah Session Object . This is my code for the delete | | graphSession = jbpmContext.getGraphSession(); | graphSession .deleteProcessDefinition(Long.parseLong(processDefId)); But I am getting this exception while executing that API | 14:40:34,147 WARN [JDBCExceptionReporter] SQL Error: 0, SQLState: 23503 | 14:40:34,147 ERROR [JDBCExceptionReporter] ERROR: update or delete on table "jbpm_token" violates foreign key constraint "fk_scopeinst_token" on table "bpel_scopeinstance" | Detail: Key (id_)=(246) is still referenced from table "bpel_scopeinstance". | 14:40:34,147 ERROR [AbstractFlushingEventListener] Could not synchronize database state with session | org.hibernate.exception.ConstraintViolationException: could not delete: [org.jbpm.graph.exe.Token#246] | at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:71) | at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) | at org.hibernate.persister.entity.AbstractEntityPersister.delete(AbstractEntityPersister.java:2541) | at org.hibernate.persister.entity.AbstractEntityPersister.delete(AbstractEntityPersister.java:2697) | at org.hibernate.action.EntityDeleteAction.execute(EntityDeleteAction.java:74) | at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:250) All the process instances are ended, in fact I only have one process instance and that is ended. Any Idea why this is happening. Do I need to do anything before calling the delete API?

[JBoss jBPM] - Re: jbpm4: could it simpler implementing an identical user i

by shekharv

Look at the eventListener folder's process.jpdl.xml in the examples that come with jbpm4. You could use something like: <event-listener class="org.jbpm.examples.eventlistener.LogListener"/> This listener could then be the base to trigger the code that you could use to dynamically build the process.

[JBoss jBPM] - Re: jbpm4: could it simpler implementing an identical user i

by rogerofyan

Thanks for the tip about forkhandler. But I don't find how to add action handler in jBPM4. what confusing me is how to dynamically create multiple child executions after a fork node, the count of child executions is unknown when design the process. Any tips is welcome. Thanks.

by kukeltje

look at the foreach forkhandler in the wiki. It is for jBPM 3 but might be adapted for jBPM 4 View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241840#4241840 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4241840

[JBoss jBPM] - Re: SQL error executing test process

by kukeltje

could also be caused by a wrong dialect (afair, I've had the same thing before once, though not jBPM related) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241839#4241839 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4241839

[JBoss jBPM] - jbpm4: could it simpler implementing an identical user in ma

by rogerofyan

Hi all, I'm implementing a homework process and illustrated in the following image: [img]http://scude.co.cc/pub_img/homework-process.png[/img] Take for example, a teacher named t1 will be the assignee of 'announce' task. and many students(let's say 20) are asked to submit their homeworks. I know that I could implement this by starting 20 process instances repectively. But I'd like to know is there simpler way to archive it, that's: the teacher t1 completes his task 'announce' only once, and 20 students will get a 'submit homework' task in their personal task list. Thanks.

[JBoss jBPM] - Re: SQL error executing test process

by shekharv

Does not seem to be a jbpm error per se. If anything the create-drop hibernate config option that you likely have in your jbpm.hibernate.cfg.xml seems to the root cause. Try not recreating the schema everytime you run the test case and it 'should' go away. This could mean though that the jbpm mysql sql script files might need to be changed a little? But again it is only in the test case world that you would recreate the tables everytime. http://bugs.mysql.com/bug.php?id=21395 View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241815#4241815 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4241815

Uhhmmmm first suggestion would be to read some docs, look at some examples, blogs etc... View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241769#4241769 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4241769

[JBoss jBPM] - Saving long spanning process in jBPM 4.0

by nazarfm

Hi all, In jBPM 3.0 we could save the state of the process to the database and later access it later. I was wondering how to do this with jBPM 4.0 since, jbpmcontext is not in the api. For those who want to know what exactly I'm doing, I have an asynchronous web-service that uses callback method. After a state initiates the web-service, I want to save the state and only when the callback method is called, I want to proceed further. Any suggestions and comments are welcome :) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241751#4241751 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4241751
