jsp操作mysql出现故障
我在做一个信息发布系统，首先要接受注册
从表单获取得数据在填充到数据库时报错
"The server encountered an internal error () that prevented it from fulfilling this request."
代码如下：
<%@ page contentType="text/html;charset=gb2312"%>
<%@ page import="java.sql.*"%>
//<%@ page language="java" import="java.util.*" session="true">
<html>
<body>
<%
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
String url=new String("jdbc:mysql://localhost/wrox?user=root&password=xiguagege520&userUnicode=true&characterEncoding=8859_1");
Connection conn=DriverManager.getConnection(url);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String operate=request.getParameter("operate");
String username=request.getParameter("username");
String password=request.getParameter("password");
String email=request.getParameter("email");
String sex=request.getParameter("sex");
String level=request.getParameter("level");
String sql="insert into user(username,password,email,sex,level) values('"username+"',MD5('"+password+"'),'"+email+"','"+sex+"','"+level"')";
ResultSet rs=stmt.executeUpdate(sql);
out.println(sql);
if(rowCount!=0)
{out.println("command has been done!");}
else
{}
rs.close();
stmt.close();
conn.close();
}
catch(Exception e)
{
out.print("Exception:"+e.getMessage());
}
%>
</body>
</html>
------解决方案--------------------
ResultSet rs=stmt.executeUpdate(sql);
返回错了吧 你编译能成功？？？？
