噪音扰民时间规定:怎样 用JSP 连接 数据库 我用的是Jbuilder x

JDBC

要在Jbuilder 里分别配JDBC 驱动和数据源，具体的记不清了。上书店看看吧。

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class TestDB {

public static void main(String[] args) {
try {
Class.forName("JDBC驱动");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
try {
con = DriverManager.getConnection("连接字符");
stmt = con.createStatement();
rs = stmt.executeQuery("SQL语句");
while (rs.next()) {
System.out.println(rs.getString("字段"));
}

} catch (SQLException e) {
e.printStackTrace();
} finally {
try {
if (rs != null) {
rs.close();
}
if (stmt != null) {
stmt.close();
}
if (con != null) {
con.close();
}
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}
