Fred,
For both cases, you should use indeed use the asynchronous features. Certainly
for the second case, it is best to rely on JMS because JMS queues are
transactional resources that you have control over. You can use MDB's that read
the messages from the queues and depending on the outcome of
i'm lost, what's the role of JMS in a ftp action?

My understanding is that the internal asynchronous messaging within jbpm is
fairly limited, though it may be enough for my purposes.
For example, if I needed to run a bunch of ftp jobs at once, I might need a
pool of "ftp runner" objects. These would sit around waiting for messages to
ftp files
i played a little bit with the "async", here is what I got:
1. create a "task-node" without "task". Using "task-node" because it does not
need a human signal as "node". It's automatic.
2. add the Customized ActionHandler under a outbout transition.
3. jbpm-web will block for long time when y
Ok, now I'm lost. What is this "jbpm-web" application? Am I missing a tool? The
only thing that I have is the plain "jbpm" war file from the starter kit that
contains a demo of the "websale" process.
Where is this "run process" button you're referring to? Or is this your code?
Thanks,
Fred

The jbpm web is the war file.
If you are using jbpm designer for eclipse:
1. create a sample jbpm project
2. modify the graph and create a customized ActionHandler
3. right click on the ".par" folder and click "deploy par achive" menu, eclipse
will ask you for the jbpm server (deault is localhos
Thanks, that's helpful. I have been deploying with ant, but I'm happy to know
about the upload mechanism.
Would you consider posting your test processdefinition.xml?
I keep getting validation errors with the eclipse plugin, and it's just as bad
when I try writing them manually. I'm collecting e
Yes, if you want to have robustness you should use JMS instead of the internal
asynchronous support, which works well for simple applications, but not for the
high end.

Thanks for your response. But can we learn at what point we need to switch from
internal messaging to JMS? What are the problems with internal messaging? How
will we know when not to use it? Does it turn blue under load? Does the CPU
burst into flames? Excess stomach acid?

gudake,
I've been trying to play with this too. I think I need to have actions on plain
rather than on tasks, because I want the external process
to control the process flow.
Isn't it true that in your experiment with async tasks, the process continued
on regardless of what happened in the asy
Sorry, the above is supposed to say "plain node", but the code got lost.

Fred,
There *is* some unreleased code wrt JMS in CVS. It will be released in the 3.2
branch AFAIK.
The moment you want to switch is really up to you. If you want to use
clustering for instance, you would have to use a clusterable JMS solution. As
long as the internal system works for you, ther
I am also trying to some thing like this . I am new to Java and jBPM . Amy
simple samples please. I posted something as a new link then I found out this
one..
Any thing will be helpful.
