EJB examples with jBPM?

[cwad0000]

I read that jBPM have a EJB that one can use,
but I cannot find any (source code) examples on this,
can someone please point me in the direction where I should look.

cheers

jBPM does not have an ejb that one can use... So it is right you could not find any source on this.

ah....the user guide is out of date then
The jBPM library can also be packaged and exposed as a stateless session EJB. This allows clustered deployment and scalability for extreme high throughput. The stateless session EJB will be written against the J2EE 1.3 specifications so that it is deployable on any application server.

Does it exist any code examples where someone created a EJB as wrapper for jBPM? Would be nice if I don't have to reinvent the wheel...

[kukeltje]

No, the userguide is not outdated, I think you should read it differently

*can* does not mean a complete implementation of this is available. It means someone can do this

Ronald

[cwad0000]

yes, but since they in the same paragaph said
The stateless session EJB will be written against the J2EE 1.3 specifications so that it is deployable on any application server

I assumed they were referring to an existing EJB
(it was not clear that it was merely a recommendation that one should make sure that such a bean meet the J2EE 1.3 specifications).

hmm... 'will be' is a future tense right ;-) it does not say 'was' or is...

Just kidding

Ronald

[dhartford]

regardless of tense, the text is mis-leading easily percieved that it already exists to offer clustering...not all of us are lawyers trying to read between the lines ;-)

Why would someone add that text to the users guide anyway?

After reading the codes, I should say jBPM have a long way to be mature, especially on the security part.

[kukeltje]

Thanks for the notifying us.

Do you have detailed issues where we could improve, since we are always open for improvement. What would you expect from a security standpoint.

Ronald

[shiyusen]

OK. It's quite clear.

1. Implement org.jbpm.security.*, so I can check a user's permission on a task instance easily, not parsing the expressions.

2. Implement org.jbpm.taskmgmt.assignment.ActorAssignmentHandler.

3. Refine the jpdl-3.1.xsd. There are too many assignments I think.

That's what I expect. ^_^

Better yet, we are even open to contributions of such items... :-)

I have implemented the expression parser for my current project. Surprisingly, it's quite easy. I'd like to take this part for jbpm at my spare time if you can add me to the project. My sourceforge id is shiys.

Shi Yusen,

Please send a private email to Tom to further handle this.

Thanks,

Oh and don't forget to refer to this thread in your email.

Thanks again,

But is it actually usable combination JBoss+jBPM without any examples ? Or too much to develop ?
