Now you can do BPEL in JDeveloper.
The BPEL team just released their new BPEL 10.1.2 Beta 3 to OTN and the great news for us is that it includes the BPEL designer working in JDeveloper.

Currently you need to download the full installation to get a new JDeveloper installation with BPEL in it. I'm hoping that for the production version, you'll be able to just download a JDeveloper extension and install it into your existing JDeveloper installation.
With all the versions of JDeveloper that I have on my machine now I'm starting to run out of disk space for my itunes library...
