Bpel4people. Bpmn 2. Bpmn 3. Working with Human Tasks. ActiveVOS server implements the operations described by the OASIS WS-HumanTask (WSHT) API task client specifications to manage human tasks as well as interact with specific tasks.
In addition to WSHT API, the ActiveVOS server also provides an extension API to the OASIS WSHT API with enhanced functionality. This document introduces the reader to the Active Endpoint implementation of the WSHT and ActiveVOS Extension APIs, and includes a few examples describing the use of the API via SOAP and indirectly via Java code using JAX-WS (ActiveVOS WSHT4J API). Readers should read the WS-HumanTask Architecture PDF document found in the docs/ directory to get an appreciation of WSHT. This document will help understand concepts necessary to the use of the API. 039; Next Big Thing Blog: OASIS BPEL4People: Beating a Dead Hors.
Loosely Coupled Thinking : BPEL4People and WS-HumanTask to OASIS. Decoupling BPM and Messaging. Decoupling BPM and messaging I was reading a post by John Reynolds asking why Java programmers hate BPM.
The response from The Java community is mixed between "programmers don't hate BPM, they hate coding in XML" to BPM is a tool for managers, not programmers. Here's my own take on why programmers hate BPM. My answer is, programmers don't hate BPM< they hate BPEL due to its complexity. Now why is that? Heck, one of the reason why the abomination that is BPELJ was introduced was to facilitate the transfer of Java objects through BPEL without going through XML serialization.
I really think the reason GRAFCETs are very successful in the heavy industry (for e.g. coordinating large scale manufacturing) is because GRAFCET is a pure boolean system (0 or 1). This really facilitates GRAFCET design a whole lot. Loosely Coupled Thinking : BPEL != BPM. Business Process Management (BPM) - Jon Pyke on BPEL4People - eb.

Write to Editor **Editor's note: Here, see Tony Baer and Keith Harrison-Broninski's commentaries on the same announcement The recent submission of BPEL4People is a good step in the right direction to bring SOA-type requirements to the carbon side of the business process conundrum. The proposed BPEL4People and associated WS-HumanTask specifications introduces the ability to delegate ownership of a task by named user. The most worrying aspect for me, however, is that the intended people support changes simply do not go far enough. Process experts such as Wil Van der Aalst (noted for his pioneering work with worklow patterns) have shown that some process diagrams can be drawn in BPMN, but still cannot be implemented using a block structured language, such as BPEL. We can take this lack of understanding a stage further. Leading Technology Vendors Announce Publication of 'BPEL4Pe.
A group of technology vendors, including Active Endpoints, Adobe, BEA Systems, IBM, Oracle and SAP AG, have announced the publication of “BPEL4People” specifications, which define an approach for integrating human interactions using Web Services Business Process Execution Language (WS-BPEL) 2.0.
Oracle Blog » Blog Archive » Workflow Futures? Oracle Workflow appears to have reached an interesting point in its life.
Very little appears to be happening; the product itself hasnt moved on very much in the past few years, and there is a great deal of uncertainty surrounding its future. In Oracle Applications release 11.5.10 there are hundreds of workflows that are part of the suite; in release 12 that grows to many more. At the moment, it is still unclear as to the future of the Oracle Workflow product as we move towards Fusion, but although there appears to be a movement towards Oracle BPEL, Oracle Workflow is still apparently superior in terms of the human involvement in workflows whereas BPELs strength seems to be in integration; the very latest version of BPEL does seem to have improved in human interaction though.

BPEL Processes and Human Workflow. Business Process Execution Language (BPEL), one of the key technologies for Service Oriented Architecture (SOA), has become the accepted mechanism for defining and executing business processes in a common vendor-neutral way.
Companies ranging from Oracle, IBM, Microsoft, SAP, and BEA to smaller organizations such as Fuego and Lombardi have committed to BPEL as a building block for SOA. BPEL, which has been designed specifically for defining business processes, supports typical interactions such as synchronous and asynchronous operation invocation, sequential and parallel flows, message correlations, fault and compensation handlers and activities triggered by events. Business processes often require human interactions as well. Since the BPEL specification doesn't address them, you might think BPEL isn't suitable for business processes that involve people. But that's not the case. Task approval is the simplest and probably the most common user interaction. The ABCs of BPM. The benefits claimed by BPM (business process management) software sound almost too good to be true.
Proponents crow about lower app dev costs, shorter time to market, improved compliance enforcement, and new points of leverage for optimizing business performance. BPM software can't improve anything by itself, of course -- but it can be a powerful weapon when combined with business-oriented documentation and analysis. Within its own controlled, high-level app dev environment, BPM wraps IT solution development within business-driven modeling and performance measurement. At the least, BPM provides an effective new medium through which the business side can communicate its requirements to IT. At best, it can distill functionality from existing applications and free business logic from the bonds of existing infrastructure to enable unprecedented agility. One persistent problem for potential adopters, however, has been abject confusion.
