Essential Business Process Choreographer reference material
The WebSphere Business Process Choreographer provides support for business-process applications within IBM WebSphere Application Server. Business processes can be automatic, recoverable processes, or processes that require human interaction. With Process Choreographer, you can combine business process technology with any other service offered by products supporting the open J2EE architecture.
Business Process Choreographer has been shipped with:
IBM WebSphere Application Server Enterprise V5

Learn about the Business Process Choreographer with these valuable, in-depth technical articles.
Selecting a human task with custom properties using WebSphere Process Server WebSphere Process Server V6.1 provides a technology called the Human Task Manager (HTM) that manages the life cycle of people interactions with business processes. An instance of a human interaction is called a task. Associated with a task is meta data called properties. Solution designers and developers can define some of these properties, known as custom properties. This article illustrates the use of custom properties for human tasks to locate specific task instances.

WebSphere Process Server V6 – Business Process Choreographer: Concepts and Architecture
Business Process Choreographer (BPC) is the component in IBM WebSphere Process Server V6 that provides support for business processes and human tasks. It allows you to model your business process using the Web Services Business Process Execution Language (WS-BPEL), and to model interactions that involve humans using human tasks. Both business processes and human tasks are exposed as services in the Service Component Architecture (SCA). This whitepaper introduces the concepts and architecture for business processes and human tasks as provided by Business Process Choreographer.

These samples demonstrate and explain the features of IBM WebSphere Business Process Choreographer. They help you to develop your own business processes and human tasks. Each sample focuses on a specific feature or modeling pattern and leaves aside other aspects.
Using human tasks in different scenarios in IBM WebSphere Integration Developer
The IBM WebSphere Integration Developer provides several editors to implement various SCA components. Two SCA component types are "human tasks" and "business processes". These components can interact in different scenarios with each other, depending on the use case. This article describes various interaction scenarios between these two SCA implementations. It also gives guidance on when to model an in-line task and when to use a standalone task in conjunction with BPEL processes.
Process Cleanup Service for Business Process Choreographer
Business processes can be defined so that when a process completes, all of its associated data remains stored in the Business Process Choreographer runtime database. This article describes a process cleanup service which takes advantage of the scheduler service and other extensions that come with WebSphere Application Server to regularly trigger cleanup actions for completed business processes. A ready-to-use sample J2EE application and its source code are provided for download.

WebSphere Process Server V6.1 Business Process Choreographer Programming Model
As part of WebSphere Process Server, V6.1, Business Process
Choreographer provides support for business processes and human tasks.
It offers a way to model your business process based on the WS-BPEL
specification, and to model interactions that involve humans, such as
human-to-human, human-to-machine, and machine-to-human interactions.
Both business processes and human tasks are exposed as services in a
Service Oriented Architecture. This white paper introduces the
programming model for processes and tasks provided by Business Process
Choreographer. (An earlier
version of this article basedon WebSphere Process Server V6.0 is also available.)

Enable generic Web services interfaces for Business Process Choreographer
In this article, you'll learn how to extend the IBM WebSphere Process
Server Business Process Choreographer Human Task Manager and Business Flow Manager APIs,
typically available only for J2EE clients, to Web services clients,
such as Microsoft®.NET™ clients.
Using compensation in business processes with Business Process Choreographer
The design and implementation of fault handling in software applications
is as important as the implementation of the normal processing, and often
requires an equal amount of care, time, and effort when building robust and
reliable applications. Faults can occur in specific situations, so you must be
ready to react to them. Faults may already exist within a business process and
can compromise the integrity of the system, so you must use process logic to
restore the system's integrity. This can be achieved by business logic that is
called in case of a failure and that reverses the effects of former service calls.
This concept is known as compensation.
This article explains the concepts and usage of compensation in business processes
that are run with the Business Process Choreographer, a component of IBM WebSphere Process Server Version 6.0.
Create a dynamic service binding with WebSphere Studio Application Developer Integration Edition V5.1
Explore the basic steps to achieving a dynamic service binding in IBM WebSpherer Studio Application Developer and WebSphere Business Integration Server Foundation in this article.

Business Process Execution Language for Web Services version 1.1 Business Process Execution Language for Web Services provides a means to formally specify business processes and interaction protocols. BPEL4WS provides a language for the formal specification of business processes and business interaction protocols. By doing so, it extends the Web Services interaction model and enables it to support business transactions. BPEL4WS defines an interoperable integration model that should facilitate the expansion of automated process integration in both the intra-corporate and the business-to-business spaces.
