The Web Services Business Process Execution Language (BPEL) is a programming language for specifying business processes that involve Web services.
BPEL is especially good at supporting long-running conversations with business partners. Even before the standard is formally released it is becoming clear that BPEL will be the most widely adopted standard for business processes involving Web services.
BPEL is geared towards "programming in the large", which supports the logic of business processes. These business processes are self-contained applications that use Web services as activities that implement business
functions. BPEL does not try to be a general-purpose programming language. Instead, it is assumed that BPEL will be combined with other languages, which are used to implement business functions ("programming in the small").
This white paper proposes a combination of BPEL with Java, named BPELJ, that allows these two programming languages to be used together to build complete business process applications. By enabling BPEL and Java to work together, BPELJ allows each language to do what it does best.
This presentation will introduce the main concepts of BPELJ and explain how they work together with the BPEL constructs. The content of the presentation will be based on the published BPELJ white paper.
