Moreover, with the increase in business, it’s very important to establish a reusable system and easier to maintain it. Presentation layer uses Struts2， business logic layer uses Spring and endurance layer uses iBatis（SSi2）, they are free lightweight frameworks and often used in Web development. After analysis of the three frameworks, the three frameworks are integrated to process LOB datas in the Web system, several key points, the advantages of hierarchical design, low coupling between the codes are elaborated through the integrate. After integrating, the maintainability and expansibility of the system are greatly strengthened.

Key words: Struts2, Spring, iBatis, LOB, lightweight, integrate
