这是我晓得的最简单的java小程序代码了你可以看看:
package com.kenki.emp;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.sql.SQLException;
import java.sql.*;

public class emp extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=GBK";

//Initialize global variables
public void init() throws ServletException {
}

//Process the HTTP Get request
public void doGet(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException {
response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
String code = request.getParameter("code");
String name = request.getParameter("name");
String pay = request.getParameter("pay");
System.out.println("empcode:" + code);
System.out.println("name:" + name);
System.out.println("pay:" + pay);
//创建驱动
new com.microsoft.jdbc.sqlserver.SQLServerDriver();
String strd =
"jdbc:microsoft:sqlserver://localhost:1433;databasename=emp_dates";
String username = "sa";
String pws = "";
try {
java.sql.Connection conn = java.sql.DriverManager.getConnection(
strd, username, pws);
String strs = "insert into emp values(?,?,?)";
java.sql.PreparedStatement pre = conn.prepareStatement(strs);
pre.setString(1, code);
pre.setString(2, name);
pre.setString(3, pay);
pre.execute();

pre.close();
conn.close();
//重定向至查询页面
out.println("成功保存！！");
response.sendRedirect("emp.html");

} catch (SQLException ss) {
ss.printStackTrace();
response.sendRedirect("/WebMole1/error.html");

}
}

//Process the HTTP Post request
public void doPost(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException {
doGet(request, response);
}

//Clean up resources
public void destroy() {
}
}
