3. 目录注意改下。“安装路径不宜有空格”！因为有时很难区分“Program Files”是代表一个文件夹还是代表“Program”和“Files”两个东西

4. 配置环境变量
www.ad119.cn/bbs/attachments/basic/20081226/2008122617539203778012.gif
5. 新建系统变量
www.ad119.cn/bbs/attachments/basic/20081226/2008122617539250778013.gif
6. 建第一个系统变量：JAVA_HOME 值：C:\j2sdk_nb\j2sdk1.4.2
www.ad119.cn/bbs/attachments/basic/20081226/2008122617539796778014.gif
7. 建第二个系统变量：CLASSPATH 值：.;%JAVA_HOME%\lib
www.ad119.cn/bbs/attachments/basic/20081226/20081226175310921778015.gif
8. 注意！是修改，不是新建。
系统变量：PATH 的新值是在原有值前加上%JAVA_HOME%\in;

9. 测试j2sdk的安装与环境变量设置是否正确
www.ad119.cn/bbs/attachments/basic/20081226/20081226175313687778017.gif
所以显示完全和新建的吻合。OK！
接着就可以用一个.java来编译为class来执行了。

6. 假如有个dos窗口停留着没关闭，并有一些运行成功tomcat和初始化信息，证明tomcat运行成功。
