网络编程与数据库连接问题。。？

PHP:
一般写在一个config.php中
$host = "localhost";
$dbName = "databaseName";
$user= "yourname";
$psw = "yourpassword";
$link = mysql_pconnect($host,$user,$psw);
mysql_select_databse($dbName);
JSP:
一般写在一个类中；
String user = "";
Stirng psw = "";
String driver = "";
算了：copy this
package mypackage;
import java.sql.*;
public class DbManager
{
private String driverName = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
private String url = "jdbc:microsoft:sqlserver://localhost:1433;databaseName=test";
private String user = "aaa";
private String password = "123";
private Connection conn = null;
private Statement stmt = null;
private ResultSet rs = null;
//private String sqlStr = null;

public DbManager()
{
try
{
conn = get
