第1次用servlet,就有问题
一个HelloWorldServlet
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorldServlet extends HttpServlet
{
public void doGet(HttpServletRequest request,HttpServeltResponse response) throws IOException,ServletException
{
response.setContentType( "text/heml;charset=gb2312 ");
PrintWriter out=response.getWriter();
out.println( " <html> ");
out.println( " <head> ");
out.println( " <title> HelloWorld </title> ");
out.println( " </head> ");
out.println( " <body bgcolor=\ "white\ "> ");
out.println( " <hr> ");
out.println( "HelloWorld ");
out.println( "你好世界 ");
out.println( " </body> </html> ");
}
public void doPost(HttpServletRequest request,HttpServletResponse response) throws IOException,ServletException
{
doGet(request,response);
}
}
一个web.xml
<?xml version= "1.0 " encoding= "ISO-8859-1 "?>
<web-app xmlns= "http://java.sun.com/xml/ns/j2ee "
xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance "
xsi:schemaLocation= "http://java.sun.com/xml/ns/j2ee web-app_2_4.xsd "
version= "2.4 ">
<display-name> Welcome to Tomcat </display-name>

<servlet>
<servlet-name> HelloWorldServlet </servlet-name>
<servlet-class> jsp.HelloWorldServlet </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> HelloWorldServlet </servlet-name>
<url-pattern> /hello </url-pattern>
</servlet-mapping>
</web-app>
===============================
两个文件用笔记本编辑好后，放在Tomcat5.5\webapps\jsp文件夹下
然后在浏览器中:http://127.0.0.1:8080/jsp/hello
显示HTTP Status 404 - /jsp/hello
type Status report
message /jsp/hello
description The requested resource (/jsp/hello) is not available
在之前编译HelloWorldServlet时，也出错，说找不到javax.servlet，javax.servlet.http,HttpServletResponse,HttpServletRequest不存在或找不到之类的提示，郁闷~
请高手指点，小弟先谢了
------解决方案--------------------
又看了次没看出来
我就把你的文件部署了下...
才发现
public void doGet(HttpServletRequest request,HttpServeltResponse response) throws IOException,ServletException
这行的HttpServeltResponse应该写成HttpServletResponse
笔误了
再出错误的话
贴出错误来吧
