学习顺序:
1.jsp/servlet/ejb,以ejb为重心,jsp/servlet作为表述逻辑层,可以作为测试ejb的辅助.
2.j2ee应用部署,j2ee服务器的管理.
3.j2ee的其他组成,如jaas,jni,jca,jms.
4.j2ee应用框架,如structs. SSH轻量级开发.
java基础-》jsp、servlet-》tomcat，然后就可以学hernate、ejb、spring、struts等框架，还有weblogic、jboss等容器
补充一点:
SSH是最重要的.也就是说的J2EE轻量级框架
struts spring hibernate 针对的对象各不相同
struts 是一个用来解决表示层的相关框架,主要用于写web页面的
spring 是为了解决企业应用程序开发复杂性而创建的
hibernate 是一个持久层的框架,主要用于与数据库打交道的东东
三个框架解决问题的点不同,又相辅相承,同时学习对j2ee的认识更深刻一些
Java 2 Platform Enterprise Edition,J2EE（JAVA2企业版）
跟J2SE（标准版）对应
比J2SE多了一些企业开发的包
我感觉越用SPRING开发，复杂度越高
