In J2EE application, modules are packaged as EAR, JAR and WAR based on their functionality

JAR：
包含企业java bean（类文件）和EJB部署描述符的EJB模块被打包作为带有.jar扩展的JAR文件

JAR: EJB modules which contain enterprise java beans (class files) and EJB deployment descriptor are packed as JAR files with .jar extenstion

WAR：
包含Servlet类文件，JSP文件，支持文件，GIF和HTML文件的Web模块打包为JAR带有.war（web archive）扩展名的文件

WAR: Web modules which contain Servlet class files, JSP Files, supporting files, GIF and HTML files are packaged as JAR file with .war (web archive) extension

EAR：
所有上述文件（.jar和.war）都打包为带有.ear的JAR文件（企业版）存档）扩展并部署到Application Server中。
