[Beginners Corner] - Re: Is an application server the right tool?
by ailes
Sorry I wasn't clear.
This is a farm of PCs that run various operating systems. Each PC is called a worker. The workers perform generic computational work for us. The architecture is actually 3 tiers, however. The servers that control the farm actually talk to a small number of manager machines and these machine in turn talk to the workers. This is done for scalability reasons.
The managers run java clients that are currently just plain java apps, i.e. no managed environment. The manager code is all created/controlled by us.
Right now we have much of the business logic and design done for both the managers and the services that ultimately control the managers and run the system. The question is whether these centralized services should also run in a simple home-grown container or whether we can host them in an application server to take advantage of the features it provides.

[JBoss jBPM] - Re: Help getting all tasks for a user
by bsmithjj
Ed,
anonymous wrote : Were you looking for a single call that combined these two lists?
Yes - After scanning the documentation (no luck on this subject), and trying the various getTask*() method calls via several lengthy deployments, and then searching these forums, I finally figured out that I need to make the several calls. It also took me ... oh 2-3 hours to do what I 'feel' should have taken 20-30 minutes with decent docs and or API methods.
Obviously, I was a bit frustrated - mainly because I think findPooledTaskInstances
JbpmContext.getTaskMgmtSession.findPooledTaskInstances( .. )
is misleadingly named - here's the javadocs:
| findPooledTaskInstances
|
| public java.util.List findPooledTaskInstances(java.lang.String actorId)
|
| get the taskinstances for which the given actor is in the pool.
|
|
This documentation says nothing about requiring the actorId on a task to be null in order for the query to return results. I think it would be more aptly named:
findPooledTaskInstancesForTasksHavingActorIdEqualToNull()
- this is where my 'obscure' comment is coming from. In order for that call to work, when I add pooled actors to a task, I have to know to set the actorId on the task to null - figured out once I looked at the HQL query in the jBPM source code.
Anyway - I think jBPM is a great software component - It has a lot of promise for implementing workflow-type systems - I also think the documentation is horrible - in contrast, the Seam documentation (which led us to using jBPM on my current project) is great.
Thanks
