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.

Hi all. Just to add that I succeeded to make remote JMS MessageListeners reliable using sslservlet remoting transport. To achieve this goal I use the remoting servlet configuration packed in JBM 1.4.6.GA.SP1:
http://anonsvn.jboss.org/repos/messaging/tags/JBossMessaging_1_4_6_GA_SP1... http://anonsvn.jboss.org/repos/messaging/tags/JBossMessaging_1_4_6_GA_SP1...
plus a few settings for SSL flavour and a JMS Connection' javax.jms.ExceptionListener which recreate the JMS Connection and Topic subscription in case of connection exception. I attach the exact configuration used:

[jBPM] - jBPM5.1 - eclipse BPMN process editor loses imports of script tasks
by Sebastien Lelarge

"jBPM5.1 - eclipse BPMN process editor loses imports of script tasks"

--------------------------------------------------------------
Hi all,
I am using the eclipse BPMN process editor v5.1.0.Final (not the new one BPMN visual editor) to design my processes and I have discovered something that is really annoying.
When using script tasks with Java code inside, I use the "imports" button to import external classes and make them available in the code executed from the task. When I save my process definition just after setting imports, they are successfully saved in the generated BPMN file for this process.
The problem is that the imports disappear when I re-open the process definition in editor to update it and then save it. When the process is saved after the update, then the imports are lost.
Is this a known problem for the plugin ? Is there something am I doing wrong in task config ?
How can I solve this problem ?
I am still using this editor because I think the new one is not very useable to configure script & user tasks. Maybe future versions will be easier and intuitive to use.
regards
