What is BPEL? What is it Good For? How does it work? What does it look like?

Workbench does not support BPEL and lacks process simulation capabilities, but its process-orchestration capabilities hit the mark.
eClarus Business Process Modeler for SOA Architects™ is a process modeling and services integration toolset which plugs into the Eclipse development framework. It delivers Roundtrip Engineering between BPMN and BPEL.
simple BPEL toolkit that a beginner can use to get familiar with
BPEL is fine for developers that are looking to link XML Web services, but may not be as effective for business users within the enterprise at large, who are working with all sorts of local objects, legacy systems and data types.
This SearchWebServices.com learning guide introduces you to Business Process Execution Language for Web services, or BPEL4WS. In this BPEL learning guide, you'll find articles, tips, expert advice, white papers and more that will explain how BPEL fits into the world of Web services.
Learn advanced BPEL concepts and best practices for development, deployment, and administration from the architects implementing them in real-world applications.
ActiveGrid est un environnement de réalisation d’applications WEB totalement intégré qui repose entièrement sur les standards XML les plus récents : BPEL, XForms, WSDL, XML Schema, XACML. L’offre d’ActiveGrid est composée d’un builder et d’un server, tout ça dans une architecture LAMP (le P devant se comprendre essentiellement pour Python).
ActiveGrid Studio makes it easy to create rich, interactive Web 2.0-style applications that integrate your existing databases, applications, and services. The ActiveGrid Studio offers graphical editors and wizards and is based completely on standard XML files so there is no code generation or proprietary metadata.
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.
The first part in this series of articles on BPEL4WS (Business Process Execution Language for Web Services) explains BPEL basic concepts, BPEL processes, and BPEL constructs. A sample BPEL process is provided. More advanced topics are covered in subsequent articles.
ActiveBPEL™ Designer is an integrated visual toolset for rapidly creating, testing and deploying composite applications based on the BPEL (Business Process Execution Language) standard. ActiveBPEL Designer is an Eclipse Ready™ technology that combines intuitive BPEL authoring tools with an embedded version of the ActiveBPEL engine technology, and is targeted at SOA architects, process designers, and Web services application developers.
XPDL is a way of moving a process from one design/simulation/analysis tool to another (about 30 tools support it today), whereas BPEL is about the nuts and bolts of sending messages from one location/service/system to another. XPDL is like XMI for business processes.
BPEL isn't about visibility, and it's not about change management, yet those are the central problems of business process management. BPEL as a technology is orthogonal to the problem of business process management. It's simply a new way to write code.
There recently has been a big realization that "Human BPM" is very important. IBM and SAP release their BPEL4People white paper. BEA buys Fuego, a notable human workflow vendor. Oracle prepares new human capabilities above (and possibly separate) from their BPEL engine. And Microsoft talks about their Workflow Foundation, which is also separate from their BizTalk EAI.
BPEL is an "execution language". XPDL is a process design format.
Intalio|BPMS is the only BPMS to natively support the BPMN and BPEL industry standards. And best of all, it's 100% free.
ActiveBPEL engine is a business process management runtime environment for executing process definitions created to the Business Process Execution Language for Web Services (BPEL) 1.1 spec, written in Java and released under a GPL open-source license
Apache ServiceMix is an Enterprise Service Bus (ESB) that combines the functionality of a Service Oriented Architecture (SOA) and an Event Driven Arthitecture (EDA) to create an agile, enterprise ESB.
Open Source BPEL Server ActiveBPEL, LLC is an open source software organization that licenses and distributes the ActiveBPEL™ engine technology. The ActiveBPEL engine is a robust runtime environment that is capable of executing process definitions created to the Business Process Execution Language for Web Services (BPEL4WS, or just BPEL) 1.1 specifications.
PXE is a modular business process execution engine with support for business processes described in the OASIS Web Services Business Process Execution Language (WS-BPEL 2.0) or in the legacy vendor specification BPEL4WS 1.1
