WS-BPEL Business Process Abstraction and Concretisation

2009
Business process management is tightly coupled with serviceoriented architecture, as business processes orchestrate services for business collaboration at logical level. Given the complexity of business processes and the variety of users, it is a sought-after feature to show a business process with different views, so as to cater for the diverse ...

Towards a Reusable Fault Handling in WS-BPEL

International Journal of Software Engineering and Knowledge Engineering, 2014
Service Oriented Architecture (SOA) is an evolution of distributed computing and it is based on the concepts of interoperable services. To enable reliable and robust service oriented information systems, it is important to establish an effective fault handling.

Access Control and Authorization Constraints for WS-BPEL

2006 IEEE International Conference on Web Services (ICWS'06), 2006
Computerized workflow systems have attracted considerable research interest in the last fifteen years. More recently, there have been several XML-based languages proposed for specifying and orchestrating business processes, culminating in WS-BPEL. A significant omission from WSBPEL is the ability to specify authorization information associating users ...

Migration Validity of WS-BPEL Instances Revisited

2013 IEEE 16th International Conference on Computational Science and Engineering, 2013
WS-BPEL processes ought to be adaptable even at run-time so as to adapt to the changing environments and requirements. It is cost-ineffective and time-consuming to restart a running WS-BPEL instance from scratch after the WS-BPEL process is changed. Instead, a WS-BPEL instance had better be transferred to the updated process.

Measuring Performance Metrics of WS-BPEL Service Compositions

2009 Fifth International Conference on Networking and Services, 2009
In this paper we present an approach to the development of monitoring solutions for processes implemented as WSBPEL service compositions. The approach allows modeling of process performance metrics in a platform-independent manner and then generating an event-based monitor model for a specific WS-BPEL process engine. We create a metamodel which enables

A Framework for Mutant Genetic Generation for WS-BPEL

2009
The rise of Web Services and their WS-BPEL compositions in recent years makes necessary to pay special attention to testing in this context. Mutation testing is a white box testing technique that has been applied successfully to programs written in different languages.

Quantitative Evaluation of Mutation Operators for WS-BPEL Compositions

2010 Third International Conference on Software Testing, Verification, and Validation Workshops, 2010
This work presents a quantitative evaluation of the quality of a set of mutation operators for WS-BPEL 2.0 (Web Services Business Process Execution Language), an OASIS standardized language for the composition of Web Services. A series of experiments is conducted, aiming to determine how selective operators are for the qualification of test cases and ...

An Approach to Validating Transactional Properties of WS-BPEL Composition

2009 Fifth International Conference on Semantics, Knowledge and Grid, 2009
As composite web services are often long lasting, loosely coupled, cross application and administrative boundaries, transactional support to integrated business via composing individual web services is a critical issue. Currently, WS-BPEL which is more expressive than traditional workflow language, has been the de facto standard for web service ...

BPELscript: A Simplified Script Syntax for WS-BPEL 2.0

2009 35th Euromicro Conference on Software Engineering and Advanced Applications, 2009
Business processes are usually modeled using graphical notations such as BPMN. As a first step towards execution as workflow, a business process is transformed to an abstract WS-BPEL process. Technical details required for execution are added by an IT expert.
