小弟用上面的代码想往数据库中插入数据,可是每次都显示下面的错误:

HTTP Status 500 -

conn.executeUpdate(sql); 这个对象方法从何而来?
你的驱动,连接,状态对象呢?
----------------解决方案--------------------------------------------------------

可以在JSP中使用一个useBean,实现和后台数据库的连接。在处理页面写<%@ page language="java" import="java.sql.*" %>
<jsp:useBean id="addBean" scope="page" class="guest.guestbook" /> //class=包名.类名
在插入语句后写addBean.executeUpdate(strSQL);

把以下文件贴到写字板，另存为.java文件，放在webapps\ROOT\WEB-INF\classes\guest类文件根目录下,以后执行数据库操作时写useBean语句就行了。

package guest; //包名
import java.sql.*;

public class guestbook { //类名
String sDBDriver = "sun.jdbc.odbc.JdbcOdbcDriver";
String sConnStr = "jdbc:odbc:guestbook"; //odbc:后面是你配置数据源的名
private Connection conn = null;
private Statement stmt = null;
ResultSet rs = null;

public guestbook() {
try {
Class.forName(sDBDriver);
}
catch(java.lang.ClassNotFoundException e) {
System.err.println("guestbook(): " + e.getMessage());
}
}

public ResultSet executeQuery(String sql) {
rs = null;
try {
conn = DriverManager.getConnection(sConnStr);
stmt = conn.createStatement();
rs = stmt.executeQuery(sql);
}
catch(SQLException ex) {
System.err.println("aq.executeQuery: " + ex.getMessage());
}
return rs;
}

public void executeUpdate(String sql) {
stmt = null;
rs=null;
try {
conn = DriverManager.getConnection(sConnStr);
stmt = conn.createStatement();
stmt.executeQuery(sql);
stmt.close();
conn.close();
}
catch(SQLException ex) {
System.err.println("aq.executeQuery: " + ex.getMessage());
}
}

public void closeStmt(){
try{
stmt.close();
}
catch(SQLException e){
e.printStackTrace();
}
}
public void closeConn(){
try{
conn.close();
}
catch(SQLException e){
e.printStackTrace();
}
}
}

老大应该这样来做
<%@ page contentType="text/html;charset=gb2312" %>

<%@ page import="java.util.*"%>
<%@ page import="java.sql.*"%>
<%@ page import="java.lang.Math.*" %>
<jsp:useBean id="conn" scope="page" class="download.conn"/>
<html>
<head>
<title>网上书店</title>
<link href="incoming/style.css" rel="stylesheet" type="text/css">
</head>
<body>

//添加
Statement stmt=conn.createStatement();

String sql="INSERT INTO BUYERINFO
VALUES('"+userid+"','"+password+",'"+username+"','"+address+"','"+phone+"','"+email+"')";
//更改conn.executeUpdate(sql);
stmt.executeUpdate(sql);
%>
<br><a class="title">已经注册成功！请<a href="login.jsp">登录</a></a><br>
<%@ include file="incoming/footer.jsp"%>
</body>
</html>

好了这样就好了你先自己来检测以下应该不会出现问题呢!

你主要是少个sql执行类Statement
你直接用conn来执行插入就不对了;..

老大。。连接数据库操作时首先应该装载驱动程序、再创建数据库连接。然后在执行增删改查操作。关于装载驱动与连接数据库有四种类型，你自己针对你自己的喜好来定。不过现在都用第四类型驱动。二楼哪们朋友写的是第一类型ORACLE的连接。可能不适合你。你用的是SQLSERVER ：
SQLSERVER
装载驱动
Class.fromname("com.microsoft.jdbc.sqlsqerver.SQLServerDriver").newInstance();
创建连接
Connection conn=java.sql.DriverManager.getConnection("jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=数据库名","sa","")
这里SQLSERVER 用户名SA 密码为空
记得SQLSERVER 打SP3以上的补丁。而且1433端口要打开哦

把javabean里头的内容也贴上来吧。

哈哈。你要继续努力了。
----------------解决方案--------------------------------------------------------

好像是类不能编译！

----------------解决方案--------------------------------------------------------
你应该把你的.java文件也写出来才能看出错误
不过你数据库连接好像错了！
