基于J2EE的网页上可交互图形的设计与实现

Design and Implementation of a J2EE-based Interactive Image on Web Page

可交互图形在C/S结构的软件系统中得到了广泛的应用,而B/S结构的可交互图形因其不易实现,应用很少。文中提出了一种基于J2EE平台的B/S结构的可交互图形的设计与实现的方法,从分析J2EE平台的架构着手,介绍了Ap plet,Servlet和EJB。着重阐述基于J2EE的网页上可与服务器端进行交互的图形的特点、数据交换原理及基于J2EE的网页上可与服务器端进行交互的图形优点,并通过网页上可交互图形在生物信息处理的应用,用对象数组传递数据信息,详细说明了基于J2EE的网页的图形与服务器端交互功能的实现过程。

<Abstrcat>The interactive images have been used in many C/Sstructure software system, while they are seldom applied in the B/S-structure software system because of they are not easy to be realized in the B/S software system. This article will propose a method of designing and implementing a J2EE-based interactive image on Web page. Firstly analyses J2EE and its architecture, introduces Applet, Servlet and EJB, puts emphasis on specifying the features of a J2EE-based interactive image on the Web page, the principle of data exchange between the browser and server and the strongpoint of a J2EE-based interactive image, specifies the implementation of interactive image exchanging data in object arrays through a application in biologic informatics.
