Abstract

To validate a web service composition, we have developed, in a previous work, a formal approach which takes into account both generic and specific properties. Generic properties can be checked for any invoked web services when the specific properties are different interdependence relationships between activities within an orchestration process. In this work, we present {\sc BpelVT}, a tool to support the proposed approach. We adopt WS-BPEL as the language to describe the web service orchestration. This specification is translated to Promela which is the input language for SPIN model-checker, in order to check generic and specific properties expressed with LTL (Linear Temporal Logic). The BpelVT tool provides the WS-BPEL manager, the automated process translation of WS-BPEL to Promela code and model-checking views.
