Answer 4

先看一些Java的基础书籍，如Thinking in java。
至于JDK，可以直接到java.sun.com网站上下载。

Answer 5

java编译器从sun公司就可获得，推荐jdk1.3版，不要用1.4
网址java.sun.com。
入门书<<think in java>><<java2 核心技术>>卷一、卷二
关于jsp,servlet,ejb这些技术最好到sun公司下载资料，市场上书很多，但大多都是相互抄袭，质量低略。
然后熟悉weblogic,websphere的使用，在熟悉db2,oracle,sqlserver的基本
使用，做项目时大多离不开这些
这也是我学java的大概过程
