Note that jBPM 4.x is not finished yet and it is mainly developed by community at the moment so please be patient. Contribution is always welcome :)
I have done some work on deployment through BPM console but it did not make it to the current release, if you like you could apply the patch and build it from source. jBPM integration part should be already included so it is a matter only of BPM console.
Here is the BPMC jira issue. https://jira.jboss.org/browse/BPMC-58
Comments are welcome too.
