Well, everything you mention is a module in the jBPM source, some even separate projects (BPEL, PageFlow, GPD) so you can easily just use what you need. The download (I assume the downloading is not the problem is it?) does contain everything, but just use the jar files/config files you need. jPDL is not a language to communicate with the PVM, it is a language implemented on top of the PVM.
