I have a BPM 10G app that uses external tasks a lot and the external UI makes heavy use of Papi. I don't mind rebuilding the process from scratch in 11G, but I'd like to keep my UI as is, or worst case scenario replace the Papi layer in it (thankfully nicely abstracted!). Is there anything like Papi in 11g, I have noticed that Human Workflow has an API, but I'm still trying to understand why this appears to go through BPEL to get to BPM, can I use this?
You may have guessed that I'm from a BEA/BPM background, not an Oracle/BPEL one! If anyone can provide a good and clear explanation as to how these components fit together, I'd be grateful - can't find a concise overview in Oracle docs at the moment.
