Can I use kie-services-remote in my custom JBPM app?

[jay.guidos-bidstrading.com]

Hi Guys,

I want to provide REST access to the Human Task service, and the API implemented by kie-services-remote looks to be  pretty much what I want. 

Is there a way to include it and start it in my custom JBPM application? Looking at the code it seems it could be possible, I am looking for some hints.

Hi Jay,

Sorry for the very late answer.

You can definitely use kie-services-remote in your application: however, figuring out all of the dependencies/artifacts/jars that it needs in order to work is a B$%#&.

kie-services-remotes relies on jbpm-kie-services for the most part -- in short, it's just a REST/JMS interface to the execution server.

Hi Marco,

You know, I came to exactly the same conclusion

I ended up re-implementing a subset of the basically the same commands, with some slightly customized calls.  I could have gotten away with using the entire REST API from kie-services-remote - and I see lots of people on this forum trying to do the same thing.  I think it would be handy to have a whole package I could add (maybe call it kie-services-remote-svc or something) that was set up to be pluggable into any web application already running KIE.  This service would basically provide a callback or listener API that I could hook into to that would handle all the REST grok-age for me and I could concentrate on what I wanted to do.

That, and a beer, and I have all I need.

Thanks for replying.

jay.guidos,

I have no clue when we'll get the time to put this together -- although, it might not be that hard. That being said, could you add your opinion to the following:

If we put together a "kie-services-remote-svc" package (or whatever it ends up being called), is it correct to say that it would only supply the following:

1. REST services (obviously)

2. Underlying connection to the jBPM runtime/engine (basically, the jbpm-runtime-manager and jbpm-kie-services module), so that processes could be started, etc.

3. Deployment management, because 1 and 2 need that

This means, of course, no UI, no guvnor, no web-designer, etc.

Is that basically what you have in mind?

Hi Marco,

What you have described is effectively what I wrote .  We use KIE Worbench straight out of the box to design processes, and then export them via GIT directly to our GUI-less stand alone execution engine.  The engine is controlled with a REST API that we fiddle with via BASH scripts and our already-existing management GUI.

So yes, that is exactly what we have in mind.
