I see that there is an OSGi bundle available and distributed with Servicemix. I have used Camel with Servicemix before and I can understand how I might integrate a camel route with an activiti model by writing a blueprint XML document describing them both.
I have separately installed Activiti Explorer in Tomcat (as for some reason I can't deploy it in servicemix).
Is there some way that the Activiti Explorer under tomcat can communicate with the process engine in Servicemix/OSGi ? (Or for that matter any other stand-alone process engine as process engines clearly don;t need to use the explorer GUI)
I can't understand if Activiti-Explorer will only work with its own process engines (perhaps ones it creates when one uploads the BPMN Process definitions) , or if it can communicate with an external service engine via REST or some other API, or if it is a matter of setting up the various service engines so that they share a common database (eg. postgres).
As you can tell, I really may have the wrong idea here, I could use some guidance on how process engines are hosted and communicate between each other and the GUI/REST-API
Many thanks
Alan
