To coincide with the 1.1 release of the Apache ODE BPEL engine, I wrote a short introductory article that's posted at InfoQ. In addition to resolving a bunch of issues, the 1.1 release is the first since ODE graduated to a top-level project.
As a teaser, if you've never seen a BPEL demo that doesn't involve SOAP, this one uses the HTTP binding support in AXIS2 to invoke a BPEL process using curl from the commandline. Have a read.
