[0096] Then its specific implementation method is:

[0097] (1) The application developer writes the service interface program Math.java

[0098] Declare the mathematical operations such as addition, subtraction, multiplication, and division to be implemented by the MathService grid service, as well as their parameters and return value types;

[0099] (2) The application developer writes the service implementation program MathImpl.java

[0100] Declare that its base class is the general grid service implementation encapsulation class provided by the middleware, and implement the MathPortType interface (this interface will be generated by the service interface program Math.java);

[0101] Same as writing a common interface implementation program, the developer writes the specific implementation code of all operations declared in the previous interface program in the program body;

[0102] (3) The application developer writes the deployment description document Math.wsdd

Abstract

Being applicable to open grid environment, the method decouples dependence between applications in upper layer and grid toolbox in lower layer. Thus, applications in upper layer can call service implementation in low layer based on unified API without need of understanding technical scheme of provider of service implementation. Releasing from coupling among grid service implementation, deployment description, service call and grid toolbox, the method makes compiling and packaging phases in developing grid application carry out without need of grid toolbox. In phases of deploying and calling grid, contents relevant to platform are automatic added to. Thus, the grid toolbox is transparent to application developer in the method. Advantages are: simplifying flow of development, combining techniques of code generation and graphic interface so as to provide convenience for developing application.

Description

technical field [0001] The present invention is used in an open grid environment, and adopts technologies such as inversion of control to decouple the dependence of the upper-level grid application on the lower-level grid toolbox, so that the upper-level application can call the lower-level service based on a unified standard API. It is not necessary to understand the specific service implementation provider's technical solution. The technology belongs to the technical field of grid computing middleware. Background technique [0002] Grid is considered to be the next generation of World Wide Web. It is a new technology that emerges with the development of Web technology. It adapts to the characteristics of the Internet and can fully realize the sharing of resources and the collaboration between tasks. With the continuous heating up of grid research at home and abroad, system standards for grid applications have been gradually formulated and improved. At the 4th Global Grid...
