Research Of Code Auto-Generation Platform Based On EJB--Design Of Component Library And Base-Class Library

Presently, many institutes and multinationals have begun to do the research about the code generator in order to meet the requirement of the industrialization process of software and shorten the period of development like IBM .They have completed many kinds of tools which are used to generate codes . According to the comparison and analysis among the criterions of component and the tools, the dissertation brings forward a kind of assumption based on the EJB ,and accomplishes some parts just as follows :First, according to the Session Fa9ade pattern in J2EE, the dissertation puts forward the multi-tier frame model and the whole system flow. It has also partitioned the whole task.In the next place, the dissertation has done the research about the component library, such as the method of classification, the method of description, and the basic management consisted of accession and search. It has also designed some relative Java classes by adopting the Data Binding.In addition, some research has been done about the library consisted of many classes which are independent of the application environment. The library can weaken the intensity and improve the efficiency of code generation.The component library and the base class library are the important parts of the code generator. They are the basic research and verysignificant to improve the whole ratio.
