Mình ko chắc J2EE khác gì với J2SE ko nhưng mà đối với J2SE muốn kết nối với DB, cần phải cài đặt driver cho nó. để cài đặt driver bạn phải tải driver ( là một file jar) tương ứng với loại cơ sở dữ liệu muốn kết nối : MSSQL, MySQ, Oracle, Sybase, ODBC. ( bạn có thể lên google gõ jar driver mysql để tìm vài tải driver để có thể kết nối đến DB mysql).
