Nowadays Web Services (WS) are the most prominent technology for
solving the key problem facing businesses - the Application
Integration (AI). To elaborate on this, both, Intra Enterprise
Integration (Enterprise Application Integration, EAI) and
Integration with Business Partners (Business Process Integration,
BPI) can be achieved by loosely coupled applications using WS
interfaces.
Here the Business Process Execution Language for Web Services (BPEL)
comes into play. It enables the definition of business processes as
coordinated sets of WS interactions (Orchestration) recursively into
new aggregated Web Services. Furthermore BPEL may be used to define
the external behavior of a service (through an Abstract Process) as
well as the internal implementation (through an Executable Process).
Although there is a variety of languages for service orchestration,
such as the business process modeling language [BPML], the language
BPEL4WS initially proposed in July 2002 by BEA, Microsoft and IBM
[BPEL1.0] has emerged as de facto standard in this area. It has been
transferred to OASIS for standardization and was released in April
2007 as BPEL 2.0.
The basis for this thesis is a graphical process modeling tool,
implemented as an Eclipse-Plugin, which was designed to be compliant
with BPEL 1.1 standard. The objective of this thesis is to extend
this tool in order to be compliant with the OASIS BPEL 2.0 standard.
