- Is there any standard way to migrate BPEL 1.1 process to
- The OASIS WS-BPEL TC has no official guidance on this
- Is WS_BPEL targeted for WS programming? Are managers
expected to learn programming languages like C# or Java to model business
process using WS-BPEL?
- BPEL orchestrates services that are exposed using WSDL
1.1. These services can be created using any language (including
BPEL), but the fact that they are exposed via WSDL 1.1 means that BPEL
need not know anything about their implementation
- What is the difference between Orchestration and
- An orchestration is from one actor's point of view, where
choreography looks at a global system and all the actors, and their
interactions, without looking at any single actor's internals. Unlike
an orchestration, there is no conductor in choreography – it is a peer to
peer set of relationships. WS-BPEL 2.0 is an orchestration language.
Examples of choreography languages include BPSS and WS-CDL.
- What is the relationship between BPMN and WS-BPEL2.0?
- There is no direct relationship between BPMN and WS-BPEL
2.0. WS-BPEL is a standard from OASIS and the BPMN specification is
currently an OMG standard for visual representation of Business
- How does WS-BPEL handle human tasks?
- BPEL was not designed for human workflow.
- What are the requirements, if any, for webservices
participating in a BPEL process? Would WS-BPEL work with RESTful
- Any web service with a WSDL 1.1 contract can be used by
or within by a BPEL process WS-BPEL 2.0 is not designed to use RESTful
services because these types of services do not use WSDL. Services to be
used by BPEL must be described using a WSDL contract.
- What would be an impact if WSDL2.0 Web services need to participate
in WS-BPEL process?
- WS-BPEL 2.0 is not intended for use with WSDL 2.0. .
- What are the best practices to map WS-BPEL’s
request/response paradigm to asynchronous request response web services?
- WS-BPEL 2.0 is specifically designed to orchestrate
long-running web service conversations. There are a number of BPEL
modeling techniques that can be used depending on the style of the
service definitions (a
non-normative example is available here). WS-BPEL 2.0 supports WSDL
1.1 one-way and request-response operations but does not support solicit-response
or notification operations (see Section 3 of the WS-BPEL
2.0 specification for additional clarification).
- Can fault handlers and compensation handlers apply at a
more detailed level than a scope?
- Yes you can specify fault handlers and compensation
handlers for each <invoke> activity
- Where does WS-Addressing fit into correlation scenario?
- WS-BPEL 2.0 does not specify the use of WS-Addressing.
WS-BPEL uses an endpoint reference, manifested as a service reference
container <sref:service-ref>, to represent the data required to
describe a partner service endpoint. A partner service endpoint may be
manifested using WS-Addressing.
- Does WS-BPEL2.0 support Xpath 2.0 and/or
- No. WS-BPEL2.0 is based upon Xpath 1.0 and
- What is a relationship of WS-BPEL to BPEL4J,
BPEL for People, BPEL for Sub-Processes and SCA?
- None of these initiatives are affiliated with the WS-BPEL
TC or the WS-BPEL 2.0 specification. The OASIS WS-BPEL
TC has no official guidance any of these initiatives.
