In this paper, we propose a component-based framework for generating simple 3D applications that aid users in the use of Web services without the need for programming. These days we can get lots of information through Web services. By using Web services, we can reduce the need to buy data packages and construct special databases in order to generate 3D information visualization systems or 3D simulation systems. Basically, we need to write some scripts or programs to access Web services. Therefore, it is difficult for users to use interactively through a graphical user interface, especially in a 3D virtual environment. Our framework uses the 3D meme media system IntelligentBox as its platform. All functions for accessing Web services are provided by 3D proxy components. Users have only to operate 3D interactive components and create composite components in order to create applications that use Web services. Users input values by means of specialized interface components, thereby creating requests to Web services, and changing visualization parameters. In this way, users can easily compose simple applications with a combination of arbitrary 3D components.
