jBPM 5 console Process Overview Execution Details Diagram

byungwoojun May 18, 2011 3:18 PM

I am using jBPM 5. Using Eclipse BPMN Process designer, I created a process flow with a mesage event node and export it to Guvnor. I am using the KnowledgeAgent.applyChangeSet to get the resources from Guvnor. So far, so good.

The process flow ran successfully and returned when it hit the message event node, was waitng for a signalEvent. I logged in the jBPM 5 Console (jbpm-gwt-console) to see the running process. In the Process Overview, there was my process. I clicked its instance and clicked the Diagram buttion to see the diagram. Then, I got the following exception:

org.drools.repository.RulesRepositoryException: javax.jcr.PathNotFoundException: com.company.auto.usecase5-image

Caused By: javax.jcr.PathNotFoundException: com.company.auto.usecase5-image

The com.company.auto.usecase5 is a process pid. What is the "-image"?

Any suggestion will be appreciated.

Thanks,

bwj

I found a blog related to this. Basically, I need to get (or create) a png (image file) and put it into the Guvnor package asset, or put it into the jbpm-gwt-graph-5.0.0.jar. I am going to test it using the Guvnor because the second option (putting into the jbpm-gwt-graph-5.0.0.jar) is not practical.

Hi Chris, Thank you ver much. The screencast shot was very useful to capture (create) a PNG file from Eclipse.
I followed the instructions but it still cannot find the png file from the guvnor package (after compilation successful).

So, this is a question for Kris Verlaen...

I changed the png file name to add the "-image" suffix using the pid, e.g.,

BPMN file name: usecase1.bpmn
pid: com.company.usecase1
PNG file name: com.company.usecase1-image.png

I exported the file to Guvnor package, it went into the Other assets... I built package (Build binary package) successfully,
I logged in jbpm-gwt-console, and try to see the diagram, but it was blank, and I still got the same mesage:

<May 19, 2011 3:31:43 PM EDT> <Error> <HTTP> <BEA-101017> <[ServletContext@26869889[app:drools-guvnor module:drools-guvnor.war path:/drools-guvnor spec-version:null]] Root cause of ServletException.

Any suggestion? Did I name the file incorrectly?

thanks,
bwj
