Custom Service Tasks from .wid file [message #1070532]

Thu, 18 July 2013 02:51

So far we used the META-INF/drools.rulebase.conf and META-INF/ServiceTaskDefinitions.wid files to define our custom tasks in the jBPM eclipse plugin (Process Editor).

I just wanted to see how this BPMN 2.0 Modeler plays with our current bpmn process definitions. We have a couple of these custom tasks defined in ServiceTaskDefinitions.wid but none of them shows up on the palette.

The same question has been asked already on this blog:

Any help is appreciated

WID files are supported by the BPMN2 Modeler and they should show up in the "Custom Tasks" toolpalette drawer. If they do not, then there's a problem. Can you please post these WID files here on this forum, or email them to me so I can figure out what's going on?

Thanks!
Bob

Hi Robert, thanks for the quick reply.

There is also a drools.rulebase.conf in my META-INF directory which point to my ServiceTaskDefinitions.wid file:

drools.workDefinitions = ServiceTaskDefinitions.wid

Here is my wid configuration:

import org.drools.process.core.datatype.impl.type.StringDataType;

Any idea why none of the custom tasks will show up in the modeler?

These are working for me. Which version of the editor are you using?

BPMN2 Editor 0.2.6.201306261903 org.eclipse.bpmn2.modeler.feature.feature.group Eclipse.org

My project is imported as maven project and has the following structure:

panther-bpmn
panther-bpmn/src
panther-bpmn/src/main
panther-bpmn/src/main/resources
panther-bpmn/src/main/resources/META-INF
panther-bpmn/src/main/resources/META-INF/ServiceTaskDefinitions.wid
panther-bpmn/src/main/resources/META-INF/drools.rulebase.conf
panther-bpmn/src/main/resources/Copy.bpmn
panther-bpmn/src/test
panther-bpmn/src/test/resources
panther-bpmn/src/test/resources/CopyTest.bpmn
panther-bpmn/pom.xml

I left out the Eclipse generated files. The modeler opens the bpmn file correctly but the custom service tasks are still missing from the palette. Does this plugin requires some additional settings in Eclipse, because I basically just installed it and tried to open the files, because it worked with the jBPM Eclipse plugin.

After installing the latest Eclipse and the BPMN2 Modeler plugin the Custom Tasks are finally showed up.

I have no idea what happened. First I though that the jBPM plugin somehow conflicted with the BPMN2 Modeler so I installed that plugin too and both plugins are working fine.

Something new that I didn't meet in the jBPM plugin are the "The InputOutputSpecification ID must be a valid ID" messages showing up in all of my processes. Do you know what causes this?

Yes, I'm currently working on the validation code so this should be fixed soon. For now it's safe to ignore these types of error messages.
