I used to work with Oracle SOA suite which has a BPEL component. The OTN on Oracle has an intro to BPEL that may get you started. See http://www.oracle.com/technetwork/articles/matjaz-bpel1-090575.html. They obviously are Oracle tech specific.
If you are an OSS guy then ActiveBpel may be your speed. Take a look at their resources: http://www.activebpel.org/samples/samples-2/BPEL_Samples/doc/index.html#introduction. Install the samples and then take them apart. See how they work and what they are doing.
