Abstract�� Single web services just provides limited functionality, it can’t provide enough functionalities for practical requirement. In order to solve the integration and collaboration problems of internet applications, it is necessary to compose several web services together to implement complex business logic functionality. Based on web service flow language (WSFL) and traditional workflow technology, a web services composition runtime system was proposed. The system is a multi-layered framework, which is made up with web services platform, web services composition processing engine, JMX registry and management center, remote management and control console and processing engine configuration and management tool. The processing engine executes WSFL-based processes, and remote management and control console can monitor and control the running process instances and processes’ history data. The system provides a uniform runtime environment for web services integration and collaboration.
