补：JSP连接数据库的两种方式

Driver myDriver = (Driver) Class.forName(数据驱动)

//取得数据库连接，数据源方式
Context myContext = new Initial Context();
DataSource myDataSource = (DataSource) myContext.loopup("DefaultDs")
COnnection con = myDataSource.getConnection();

//POOL连接池
Properties props =new Properties();

props.setProperty("user", "system");
props.setProperty("password", "zjxyzken");

Driver myDriver =
(Driver) Class.forName("weblogic.jdbc.pool.Driver").newInstance();

Conn = myDriver.connect("jdbc:weblogic:pool:mysqlPool1",props);
