    Business process choreography with websphere
    (Informatik 2004, Informatik verbindet, Band 2, Beiträge der 34. Jahrestagung der Gesellschaft für Informatik e.V. (GI), 2004) Kloppmann, Matthias
    Business Processes play a key role in Business-to-Business (B2B) and Enterprise Application Integration (EAI) scenarios by exposing the appropriate invocation and interaction patterns. They also introduce a two-level programming model for building heterogeneous and distributed applications (workflow-based applications). Business Process Execu- tion Language for Web Services (BPEL4WS) provides the language to specify business processes that are composed of Web services as well as exposed as Web services. In this talk we show how IBM's J2EE Application Server WebSphere provides such an environment to run business processes, called Process Choreographer. We also show how Process Choreographer allows to leverage the additional capabilities of J2EE and WebSphere, such as support for people participating in business processes, support for transactions, and support for direct access to Java.

    Web services invocation framework: A step towards virtualizing components
    (XMIDX 2003, XML Technologien für Middleware – Middleware für XML-Anwendungen, 2003) König, Dieter; Kloppmann, Matthias; Leymann, Frank; Pfau, Gerhard; Roller, Dieter
    Initially, Web services had to do with communication between executables via ubiquitous Internet protocols and technologies. But in the meantime, Web services are used as virtualization layer for any kind of executables, both within an enterprise as well as across enterprises. As a consequence, any kind of protocol and communication technology must be supported to allow users to stay in the Web service paradigm when communicating with program functions. We introduce the Web Services Invocation Framework (WSIF) which provides a flexible runtime environment for the invocation of Web services. With a client interface that is independent from the actual invocation protocol, it supports an extensible set of protocol bindings, and performs the Web service invocation in a fully dynamic or completely compiled style. We describe the major properties of the architecture of WSIF, explain its extensibility concepts and describe its client programming model.
