| Web services technology are required to enterprise application integration for data exchange among different systems. Web services have already become the absolutely necessary technology in enterprise application integration. But because of the protocol which web services based on, makes web services can't maintain it's state in service, and lead the efficiency, security badly when use web services. So, how to maintain the state becomes the important problem in using web services.We also encounter how to maintain web services' state in digital campus of Zhejiang University. In order to solve this problem, this paper present a model for maintaining web services' state, and based on this model we develop a stateful frame. we combine this frame and axis to maintenance web service's state in digital campus.Firstly, the paper introduces some technology related to web services. Based on this theory, we provide the web services' state model based on axis. The model doesn't modify the web services, oppositely, it develop the model based on web services. The model contains three models, such as services' address model, services' resource model and resource property model. The services' addressing model is the foundation of web services' state model. We use it to identify services' status for identifying resource. The services' resource model is the core of web services' state model. We use it to manage resource's state and lifecycle to managing services' state. And in resource property model, we provide a method to consistence accessing resource property, in order to unified maintain resource. Also we provide a tool class to generate client's code, which give more convenient for frame's user. Lastly we develop a web services' stateful frame based on axis according to this model.As the exploration of constructing web services' stateful frame based on axis, this paper research has received the good effect. In goes in the work, will perfects and enlarge the function of this frame. |
