Welcome to the WS-CDL+ Execution Engine Project
 
WS-CDL+ Execution Engine is based upon the WS-CDL specification by W3C with six aspects of extension mechanisms, which are variable initialization, user-defined functions, extended interaction method, timer, debugging/exception and implicit finalization mechanism. This project aims at providing an implementation of the WS-CDL+ execution engine, which can be run as a plug-in on such as application servers as Tomcat or JBoss.

We've advanced the current state of the Web service collaboration technology by addressing the following two issues: a) A prototype implementation of a WS-CDL+ execution engine. The study of WS-CDL calls for an execution engine; so that we can experiment on the properties we are working on, and develop applications using WS-CDL. The availability of a WS-CDL execution engine is also crucial to bring WS-CDL into application field, enabling a WS-CDL document to run on servers. Moreover, with the prototype system, researchers and developers are able to simulate their choreography process and get the results of choreography in a single computer without having to interact with the real WS-CDL/WS-CDL+ participants, which makes testing and debugging WS-CDL/WS-CDL+ documents easy. And b) the extension of the WS-CDL specification into WS-CDL+. It is no debut that the idea underlying WS-CDL is fascinating; however, when it comes to the application field, its expressiveness and usability become questionable. To enhance it in this way, we introduce six extended functionalities into the WS-CDL+ execution engine, including the user-defined functions, the interaction model extensions, the implicit finalization mechanism, and etc.
