Design And Implementation Of Web Services Container Based On Modular Framework

Constructing an open and scalable integrated framework of system designing tools is one of the key technologies of the distributed collaborative-development realization. By web services technologies, modules of designing tools can be wrapped as web services and integrated into the framework, which will not only satisfy the requirement of the distributed collaborative application well but also reduce the complexity of their development greatly. Therefore, it is necessary to provide a reliable service runtime environment for the framework. However, available service containers bind the function realization codes and the container process codes together in the service developing, thus the service is tight-coupled with the container, which increases the work load of developing and maintaining and makes the dynamically loading of services impossible.In order to resolve problems above, a combinative and dynamic extended web services container is proposed, which is also named a Modular Framework based Service Container. Python embedding technology is introduced in as a dynamic language module to separate the implementation of the container process and service function, which improves the development efficiency obviously. Moreover, the response efficiency of service container to concurrent mechanism is also analyzed in this paper. For this problem a service component invocating framework is designed and implemented in this paper, which reduces the response time of service container to the concurrent service request sharply and improves the efficiency of the system greatly.Experiments show that the Modular Framework based Service Container effectively reduces the coupling degree between the container and services development, so as to make the service development more efficient and the operation the service more stable.
