Hi Serg, You are right ? somehow, when I updated the user guide for version 1.1.Beta2, I left out the explanation of the bpel-application.xml descriptor. You can find the missing explanation in section 4.3.6.2 of the user guide for 1.1.Beta1. In addition, the XML Schema document for this descriptor resides in src/bpel/org/jbpm/bpel/xml/util/bpel_application_1_0.xsd. I created BPEL-219 to track this issue. Happy holidays!
