Abstract: The architecture of J2EE applications is analyzed, and the main reason that platform depended deployment descriptors make applications can not achieve “write once, run anywhere” is also pointed out. The method of intelligent container simulation is proposed. XSLT and Java technologies are adopted to realize low-cost migration and runtime compatibility in this method. Experiments about pet store applications prove that this method is effective, feasible and valuable to study deeply.

摘要： 分析J2EE 应用程序的体系结构，指出平台相关的扩展部署描述符文件是导致组件无法实现“一次编写、到处运行”的主要原因。提出了智能容器仿真方法，该方法采用XSLT 和Java 技术，在WebUniverse 中实现J2EE 应用程序的无缝移植和运行时兼容。通过对WebLogic和WebSphere 两个版本的Pet Store 应用程序的测试表明，该方法有效可行，有继续深入研究的价值。
