the conference is keeping us busy, but i'll try to answer in the gaps. 0. the project aims at supporting versions 1.1 and 2.0 of the bpel standard. internally, the engine adheres to 2.0 semantics. we support 1.1 via xsl transformations and certain runtime provisions to maintain backwards compatibility. support for other relevant ws standards such as ws-security and ws-addressing, among others, are provided by the jboss web services stack. see the jboss spec status page for details. 1. I'm not sure I understand what you mean by old-fashioned axis web services. you should be able to invoke services implemented in axis or any other stack. on the other hand, jboss bpel relies on the standard web services for j2ee model for providing services. you need a stack that implements the ws4ee apis (axis does not). if you are experiencing a problem invoking your axis-based service, let us know the full details via our issue tracking system.
