Hi Valery,
I did try your case and everything works as expected. My test environment is different though.
I use Tomcat 6 with Hsqldb and as I mentioned before I do deploy directly to data base without container and the execute processes using BPM console.
If you import examples from jBPM distribution to your eclipse, you will find example build.xml that deploys everything directly into db and the you can us it on already running process engine.
If you like I can post complete eclipse project with deployment setup (for hsqldb but it is just a matter of changing hibernate connection settings).
Cheers,
Maciej
