Hi,
Your logic might be perfectly fine, but I noticed a couple things I do differently.
I uploaded a step-by-step instructions on how to invoke PAPI from Java (JDeveloper 10) for Oracle BPM 10g Enterprise Standalone to: http://www.4shared.com/file/119420269/57ff2b24/Oracle_BPM_Enterprise_Standalone_PAPI_from_JDev.html.
