看你要运行什么样的JSP 了
比如用到javabean

谢谢您！

  《jsp应用开发详解〉上说把.jsp保存到\tomcat\webapps\目录下就可以，可是拷过去说：
xxx.jsp is invalible .
结果拷在\tomcat\webapps\root就可以，到底怎么回事啊？要是做项目也把所有的.jsp 都拷在\tomcat\webapps\root吗？

在webapps文件夹里建一个project文件夹,把编好的页面文件例如example.jsp放进去,访问时,ie地址栏里写入../project/example.jsp就可以了

用写字板打开Tomcat/conf/Server.xml文件,在最后一个</Context>和</Host>之间加入如下代码:
<Context path="/xxxx" docBase="d:/yyyy" debug="0" reloadable="true">
</Context>
即可,将文件存放在"d:/yyyy"目录下,在IE浏览器的地址栏中输入:
http://localHost:8080/xxxx/ffff.jsp
即可运行你的JSP程序,其中:"xxxx"是JSP的虚拟目录,你可以随意设置;"d:/yyyy"是你的JSP网页文件存放的任意目录,你也可以随意设置;"ffff.jsp"就更是你亲手编写的最令你得意的JSP网页程序了.

不对呀？我用了可是出现这个问题
HTTP Status 404 - /jsp/index.jsp

--------------------------------------------------------------------------------

type Status report

message /jsp/index.jsp

Apache Tomcat/4.1.31



还有就是我第一次运行输入http://localhost:8080/index.jsp进去后按书上说按
JSP Examples

然后看到
JSP Samples
This is a collection of samples demonstrating the usage of different parts of the Java Server Pages (JSP) specification.

These examples will only work when these pages are being served by a servlet engine; of course, we recommend Tomcat. They will not work if you are viewing these pages via a "file://..." URL.

To navigate your way through the examples, the following icons will help:

记住:在你对系统配置做的任何改动以后,不要忘记关闭Tomcat服务器并重新启动,否则不会生效.
