The BPEL engine is not free - it costs money.
The BPEL designer is free and is part of JDeveloper and JDeveloper works on Mac.
The tricky part is that in the 10.1.2 release of BPEL you can't install just a BPEL extension to JDeveloper you have to install the whole beast - and the packaging of the whole beast doesn't come for Mac.
In 10.1.3.1 BPEL is an extension that you can install onto JDeveloper so hopefully also on Mac.
Could any one please tell me how to install and use BPEL on Mac OS X (G5)
i am having Jdeveloper but here createing BPEL project is not allowing ,could any one tell me the steps
Thanks in advance.
