"Domain-specific processes not registering"

--------------------------------------------------------------
Hi All,
I'm trying to create a domain-specific process. Following the instructions in the
manual ( http://docs.jboss.org/jbpm/v5.1/userguide/ch13.html#d0e3557
http://docs.jboss.org/jbpm/v5.1/userguide/ch13.html#d0e3557), I placed the .wid and .conf
files in a new META-INF folder off of the project's resources folder, i.e.:
workspace/<project base>/src/main/resources/META-INF
but the new process doesn't show in the Eclipse BPMN editor. I know Eclipse isn't
finding it because I excluded the default "WorkDefinitions.conf" file, but it
still shows the "Log" and "Email" tasks under "Service
Tasks". So the folder must not be included in my classpath correctly. It's
included under *Properties | Java Build Path | Source*. I tried including it under *Order
and Export* as well, but that didn't help so I removed it. I'm pretty sure my
syntax in the .conf and .wid files is correct (nearly identical to what the doc shows).
Any idea what I can do to resolve this?
Thanks in advance!

Hi Chris, hope this video helps you:
http://people.redhat.com/kverlaen/DomainSpecificWorkItem.swf
http://people.redhat.com/kverlaen/DomainSpecificWorkItem.swf. It's an older video but
still really good...just make sure the file extension is .wid because this has changed
since. If you are working with a maven project (not a drools project) it gets a little
tricky, but you just have to make sure that the folders with your configurations are
actually set as source folders in the project settings.
If you are using the new BPMN2 Eclispe editor I really do not know if this feature is
supported there. The web designer fully supports workitem definitions saved in Guvnor, for
this check out these videos: http://vimeo.com/24288229 http://vimeo.com/24288229 ,
http://vimeo.com/26126678 http://vimeo.com/26126678.
Hope this helps.

Thanks, Tihomir. I like the video, but it's adding a DSP to a rule resource, not a
workflow. Can DSP be added to workflows or just rules? And what is the difference between
"rules" and "workflows"? Are rules just called by workflows? I
haven't seen this discussed in the docs. And the docs I linked above make it sound
like DSP can be implemented for workflows. Following the video, the DSPs don't show up
for workflows.
I have to say, I'm having serious misgivings about jBPM5 (5.1 specifically). I
recommended our project use it for a workflow process solution based on the initial
documentation and recommendations I heard for it online: "mature",
"stable", "robust". With nearly every experiment I've tried to do
with it, I've run into roadblocks and crashes. I realize this is a community-developed
product, but is there a stable version with complete documentation? We'd even be
willing to pay for support, but JBoss doesn't seem interested in our money. Is there
some reason anyone can give me for choosing jBPM over something else, like Activiti?

I assume here you are refering to
http://people.redhat.com/kverlaen/DomainSpecificWorkItem.swf
http://people.redhat.com/kverlaen/DomainSpecificWorkItem.swf. Not sure why you think its
added to a rule resource, maybe because of the .rf extension to the process file? As
mentioned, this is an old video from the drools-flow era, and the file extension for
processes was .rf (rule-flow). These files used a proprietary xml standard (similar but
not same to jPDL in jBPM 3.x and 4.x). jBPM5 uses the BPMN2 standard as the default
process definition language. However, the notion of being able to add
"domain-specific" nodes into your business process is something that already
existed in drools-flow, from which jBPM5 was born, and most of the same rules and
configuration options (especially in eclipse env.) still apply. This chapter
http://docs.jboss.org/jbpm/v5.1/userguide/ch13.html
http://docs.jboss.org/jbpm/v5.1/userguide/ch13.html of the docs I belive explains well
what a domain-specific extension is. Not many BPM engines AFAIK have this feature built in
natively so it's a really nice thing to have.
> Are rules just called by workflows? << The BPMN2
specification defines a BusinessRuleTask node which is an extension of the Task node and
is able to call upon some defined rules. jBPM follows this spec and is able to execute
Drools rules in an user-defined ruleflow-group when this node is encountered in the
process. The tight integration between jBPM5 and Drools also allows you to specify rules
in sequence flows, script tasks, etc.
> With nearly every experiment I've tried to do with it,
I've run into roadblocks and crashes. << I am first of all sorry that you ran
into issues. However believe that you would have had a very similar experience with other
OSS type of BPM solutions. The difference is how quickly you receive(d) help and quickly
you can overcome these issues/questions that is important, and I think in your case this
time has been fairly if not very quick.
> We'd even be willing to pay for support, but JBoss
doesn't seem interested in our money. << This is not good, and if you can please
email me directly at tsurdilo at redhat dot com and I will make sure that your message
gets forwarded to the appropriate people to make sure they contact you. Currently we are
running a jBPM5 pilot program, and you would be more than welcome to take part of that.
> Is there some reason anyone can give me for choosing jBPM over
something else, like Activiti? << My opinion is of course biased so I will not
comment on this. It is ultimately your decision on what software you use :)

Thank you. The fact that the video is outdated is probably whats holding me up. I like the
visual implementation because its easy to follow step-by-step and pause and rewind when
necessary. But the fact that it's showing something I'm not seeing is what threw
me. Even so, following the steps it showed, the DSPs did not show up for my workflow.
I emailed you. Thanks for all the support!

I am still unclear on the type of eclipse project you are working with. If it's small
project maybe you could provide a zip so we are on the same page? Also what Eclipse BPMN2
editor are you using?

I'm just doing a test project right now, to try and get DSP working. It's nothing
special; I have 3 script nodes, each which just prints out a string to the console. I
wanted to implement another +custom+ one (a DSP) that does something similar, just as a
proof-of-concept, just to see how it's done. I'm using the old Eclipse BPMN editor
(not the new one, which I couldn't get to work).
