Research and Design of a J2EE Framework Based on XML

According to J2EE model, proposes a Web application framework based on XML is pro-posed in the paper. We use XML as the data alternative format among layers and use ap-plication controller to handle the request intensively and modularizely, furthermore, supplies a series of service discreteness in business layer and apply connection pool to realize the efficient data access in persistent layer. The instance proves that this framework can effec-tively reduce coupling, improves the system expansibility and development efficiency.
