How did you do to avoid the IdentityService null?
I've been struggling with that for weeks, I'm using jbpm 4.4 and have the default configuration, that is:
<?xml version="1.0" encoding="UTF-8"?>
<jbpm-configuration>
<!-- <import resource="jbpm.default.cfg.xml" /> -->
<import resource="jbpm.tx.spring.cfg.xml" />
<import resource="jbpm.jpdl.cfg.xml" />
<import resource="jbpm.identity.cfg.xml" />
<import resource="jbpm.businesscalendar.cfg.xml" />
<import resource="jbpm.console.cfg.xml" />
<import resource="jbpm.jobexecutor.cfg.xml" />
<script-manager default-expression-language="juel"
default-script-language="juel"
read-contexts="execution, environment, process-engine, spring"
write-context="">
<script-language name="juel"
factory="org.jbpm.pvm.internal.script.JuelScriptEngineFactory" />
</script-manager>
<transaction-context>
<object class="identitySession" />
</transaction-context>
<hibernate-session current="true" />
</jbpm-configuration>
I tried to initialize identityService adding it as a bean in applicationContext-process file, like this:
<bean id="identityService" factory-bean="processEngine" factory-method="getIdentityService" />
Any ideas?
Thanks
Dámaris.

[jBPM] - jBPM 5.1 released

We're proud to announce the release of jBPM 5.1.0.
> jBPM is a flexible open-source Business Process Management (BPM) Suite. The core of jBPM is a light-weight, extensible workflow engine written in pure Java that allows you to execute business processes using the latest BPMN 2.0 specification. It can run in any Java environment, embedded in your application or as a service. On top of that, it supports a lot of tooling to support the business process through its entire life cycle, both for developers and business users. This includes an Eclipse plugin, web-based Designer, repository, management console, etc.
>
You can download everything https://sourceforge.net/projects/jbpm/files/jBPM%205/jbpm-5.1.0.Final/ here.
jBPM 5.1 includes a lot of small bug fixes and feature enhancements based on the feedback we received from the community (for http://kverlaen.blogspot.com/2011/01/jbpm-50-released.html jBPM 5.0). Most important improvements include:
* The web-based http://docs.jboss.org/jbpm/v5.1/userguide/ch10.html Designer has been extended significantly to support all BPMN 2.0 constructs and to allow full round-tripping between the Eclipse-based and the web-based editor. It also supports domain-specific nodes now, can be embedded, etc.
* A new http://docs.jboss.org/jbpm/v5.1/userguide/ch08.html jbpm-examples module contains a large number of example processes to show features like human tasks (including data passing and task forms), looping, multiple instances, rule-based integration, etc. I will describe some of these examples in more detail in some additional blog entries in the next few days.
* Improved testing and debugging capabilities so you can easily http://kverlaen.blogspot.com/2011/04/junit-testing-your-jbpm5-processes.html JUnit-test your processes.
* The http://docs.jboss.org/jbpm/v5.1/userguide/ documentation has been refactored, updated and extended. There's a new http://docs.jboss.org/jbpm/v5.1/userguide/ch01.html Overview and http://docs.jboss.org/jbpm/v5.1/userguide/ch02.html Getting Started chapter, and much more. And we'll continue this work in the next few weeks as well, so you can expect more details soon.
* The http://docs.jboss.org/jbpm/v5.1/userguide/ch09.html new BPMN 2.0 Eclipse plugin has made significant steps forward as well. The goal of this new editor is to support the full BPMN 2.0 specification . It's still work in progress but it can already be used to create executable BPMN2 processes and execute them on jBPM5. We'll be working hard to improve the usability in the next few months.
* Smaller feature enhancements, like
* Automatic synchronization of processes in the jbpm-console when new proceses are deployed on the Guvnor repository
* Simplified data passing to and from human tasks (and forms)
* Extended BPMN2 engine with support for repeating timers
* Support for multi-threading
A full overview of everything that was included can be found in the https://issues.jboss.org/browse/JBPM jBPM JIRA.
http://docs.jboss.org/jbpm/v5.1/userguide/images/Chapter-Overview/Overvie... http://docs.jboss.org/jbpm/v5.1/userguide/images/Chapter-Overview/Overvie...
jBPM 5.1.0 is synchronized with Drools 5.2.0, which also has just been released. If you want to know more, take a look http://blog.athico.com/2011/06/drools-52-released.html here.
I'd like to thank everyone that contributed to this release! This includes not just the core developers obviously, but everyone in the community that contributed in one way or another, from testing, improving documentation, creating examples, bug reporting to submitting patches and feature contributions!

[jBPM] - Tasks definition extension points
by Marco Piraccini
Marco Piraccini [http://community.jboss.org/people/mpiraccini] created the discussion
"Tasks definition extension points"
To view the discussion, visit: http://community.jboss.org/message/612158#612158
--------------------------------------------------------------
Hi Guys,
I'm looking for a (smart) way of extending Tasks definitions with custom attributes, in a way similar to the one used with "drools" attributes.
For instance, if we have:
<bpmn2:task id="(...)" drools:taskName="Application" name="Task2">
(...)
</bpmn2:task>
...I'd like also to define:
<bpmn2:task id="(...)" drools:taskName="Application" custom:group="test" name="Task2">
(...)
</bpmn2:task>
...where the "group" attibute is defined by me.
Now, I'd like to get these values in my WorkItems, so that I can use them in my (custom) WorkItemHandler.
Looking at the JBPM code, the correct strategy seems to be (correct me, if I'm wrong) to load them in the org.jbpm.bpmn2.xmlAbstractWorkHandler class and to put them as WorkItem "Metadata".
Now the question is: Is my reasoning is correct ore there's a smarter way to obtain the same thing? Becaus if i'm not wrong, I have to modify the JBPM code to implement that...
Marco.
