I'm assuming due to the PEBKAC that you got this figured out, but just in case
- are you clear that you don't need to actually do anything to have your custom
hibernated types saved by jbpm?

Good afternoon.
We're basing a medium sized application on jBPM, and had been using 3.0.
Having modified it to suit our purposes a bit, we noted that many of the
modifications we had made were covered in 3.1, so we went at an upgrade.
not a terribly difficult process, but there were some

I've clarified the fix a bit and posted a more defined explanation from my POV
and a fix.

to do it with an in mem db you'll also have to set the hibernate config to
autocreate the tables for you. see the hibernate docs on how to do this.

There is built in support for the primatives, byte[], String, Serializable, and
most importantly, automatic and transparent support for using your domain
objects in the process if you're using Hibernate as a persistence mechanism.
There is one gotcha to the last thought though, and I JUST
I suppose you could persist it as a byte[], jBPM will persist them, but there
will likely be issues with a blob that big (talking on pure assumption here).
The alternative is to store some reference to your document in the process, and
reference it when you need to with a link or some such
using a custom extension to TaskInstance and some custom logging you can get
the desired behavior. Patience and use of the source will guide you - we
needed and got the same thing working, so I know it's possible.
Good luck.

using the names of the swimlanes and a custom assignment class is another trick
that works well for me.
Or using a named user that is stored in the process as a variable and then
again using swimlane name as a key into which one you want - nearly no code,
but nice flexibility.

I agree with the first response - many of the advanced things in jBPM are
really customizations/extensions that are revealed as you read the user guide
and come to understand the possibilities.
for example we've built:

yeah, so everything was working fine with the unit tests (transactions are not
being simulated perfectly apparently), as in the actual web app there is a
problem with the jBPM perfectly recognizing the hibernateable types and doing
the right thing.
Long story short, my domain class is
I agree that you don't want to be using the jBPM tables in your domain, I'd
encourage you to look at either writing converters OR switching to jBPM 3.1.
You can write converters in either version, allowing you to reference full
domain objects in the process (including in scripts via the
Good evening,
I've been working with 3.1.2, and was in love with the concept of transparently
persisting hibernatable domain objects within a process.
There is a slight, what I would call counterintuitive problem with the default
variable mapping config file related to this though... objects
I'll post a patch when I implement the real solution. Currently we want this
to happen always, so we made a quick modification to TaskMgtInstance only. To
impl the patch fully there will be a bit (just a little) more effort.
I'm waiting to hear from any of the jBPM devs on the general

You'll programatically attack things slightly different is you're coming from
the web tier rather than a fat client.
Then variable type comes into play - from the web tier specifically you'll have

the previous post is dead on in my experience, and we use the null actorid
versus a non-null extensively to determine where a task is to be displayed.
You're using the identity module...

jBPM has a very open API, so yes, you can connect it. I'm assuming you want to
do task based assignments based on AD roles/groups?
Do a bit of LDAP programming and you'll see that there are a number of
possiblities.
Related to logging into a jBPM application with AD credentials... you'll
don't recall the exact setting, but you'll need to add mem to the connection

Swimlanes are a very effective way to perform assignment, and we have
