As far as I know, that is current limitation of jBPM console, it works only with default package. An extract from documentation
The current integration with the jbpm-console uses the following naming conventions to find the artefacts it needs (though we hope to update this to something more flexible in the near future):
- All artefacts should be deployed to the "defaultPackage" on Guvnor (as that is where the jbpm-console will be looking)
- A process should define "defaultPackage" as the package name (otherwise you won't be able to build your package on Guvnor)
