在Tomcat下JSP、Servlet和JavaBean环境的配置

臧圩人

感谢楼上的提醒
已修改

当我在进行第三步：建立自己的jsp app目录
页面显示：
The requested resource (/myapp/index.jsp) is not available.
为什么？

看看是不是有配置或文件夹，文件使用了中文名？

错在什么地方啊

臧圩人

编译的时候没有把servlet的api加到classpath中

lyyb2001

看来是连java.sql.*包都没有引入

臧圩人

最初由 lyyb2001 发布
[B]看来是连java.sql.*包都没有引入 [/B]
