ขอสอบถามเรื่อง การเชื่อมต่อ กับ Oracle JDBC ผมไม่สามารถ ต่อได้คับ

	        java.sql.Connection con = null;
		String url = "jdbc:oracle:thin:@10.192.44.65:1521:orcl";
		String driver = "oracle.jdbc.driver.OracleDriver";
		String user = "bcpdbms";
		String pass = "xxx";
		try {
			Class.forName(driver);
			con = DriverManager.getConnection(url, user, pass);
			if (con != null) {
				System.out.println("Got Connection.");
				DatabaseMetaData meta = ((java.sql.Connection) con).getMetaData();
				System.out.println("Driver Name : " + meta.getDriverName());
				System.out.println("Driver Version : "+meta.getDriverVersion());
				System.out.println("Got Connection success....");
			} else {
				System.out.println("Could not Get Connection");
			}
		} catch (Exception e) {
			System.out.print(e.getMessage());
		} finally {
			if (con != null) {
				// con.close();
			}
		}
