急!servlet编译通过,没有结果怎么处理?

import java.io.*;
import java.text.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.net.URL;
import java.sql.*;
public class SelectData1 extends HttpServlet
{
    public void doGet(HttpServletRequest request ,HttpServletResponse response)
    throws IOException,ServletException
{
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        out.println("<html>");
        out.println("<body>");
        out.println("<head>");
        out.println("<title>这是一个使用Serverlet数据库查询的例子<title>");
        out.println("</head>");
        out.println("<body>");
        out.println("<h1>Servlet查询数据库</h1>");
        out.println("<pre>");
       
       out.println("</body>");    
       out.println("</html>");
}
}
其中dsn用另外java程序测试没有问题,编译正常,结果没有显示

    public void doGet(HttpServletRequest httpservletrequest, HttpServletResponse httpservletresponse)
            throws IOException, ServletException
        {
            httpservletresponse.setContentType("text/html");
            PrintWriter printwriter = httpservletresponse.getWriter();
            printwriter.println("GET Request. No Form Data Posted");
