<url-pattern>/</url-pattern>

你这里面是空的所以显示不出来

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class HelloWorld extends HttpServlet
{
public void doGet(HttpServletRequest req,HttpServletResponse res)
throws ServletException,IOException
{
res.setContentType("text/html");
PrintWriter out=res.getWriter();

out.println("<html><head><title>Hello World</title></head>");
out.println("<body><b>Hello World</b></body></html>");
out.flush();
}
}
