I still think that jBPM should be the action framework. They already
have, or are going to want to have the same features as ESB's action
framework, plus more. Might as well work together. If you want to
integrate with something like BPEL, then integrate at the inbound
connector layer (the connector exposes a WS or BPEL friendly interface),
not as the action framework.
No matter what, we should provide a simplified, default model. IMO, it
is absolutely ludricrous to have a 181 as your component model for
actions. Absolutely crazy. It provides zero value. A POJO model with
local EJBs or Spring/MC +/- Seam is what we should promote.
We're JBoss. We lead, not follow. Take a page out of the Spring
playbook: Show innovation, integration, and added-value and you don't
have to follow these gay specs like JBI 2.0 and SCA. That's what Seam did.
