恳请高手帮忙 问个简单的初级问题
这个是welcome.html放在root（tomcat6.0）目录下
<html>
<head> <title> Welcome you! <title> </head>
<body>
<form action= "welcome " method= "get ">
请输入姓名 <input type= "text " name= "user ">
<input type= "submit " value= "提交 ">
</form>
</body>
</html>
下面是写的servlet WelcomeYou.java
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.*;
import javax.servlet.http.*;
public class WelcomeYou extends HttpServlet
{
public void doGet(HttpServletRequest req,HttpServletResponse resp)throws IOException
{
String user=req.getParameter( "user ");
String welcomeInfo= "welcome you "+user;
resp.setContentType( "text/html ");
PrintWriter out=resp.getWriter();
out.println( " <html> <head> <title> ");
out.println( "Welcome Page ");
out.println( " <title> <head> ");
out.println( " <body> ");
out.println(welcomeInfo);
out.println( " <body> <html> ");
out.close();
}
}
编译后的class文件放在了root目录下的WEB-INF目录下的classes目录下
WEB-INF的下的web.xml我配置如下
<?xml version= "1.0 " encoding= "ISO-8859-1 "?>
