IBM BPM - Date

Bởi -
I. Giới thiệu Date là kiểu data đã quá quen thuộc với chúng ta. Trong IBM BPM thì Date có phần hơi khác một chút so với Date trong javascript thuần. II. Sử dụng 1. Tạo date theo ngày hiện tại // Cách 1 tw.local.date = new Date(); // Cách 2 tw.local.date = new tw.object.Date(); //Cách 3: tw.local.date = new TWDate(); // Chú ý: Có thể dùng biến var thay cho tw.local (var date ~ tw.local.date) 2. Tạo date theo ngày bất kỳ // Cách 1: tw.local.date = new TWDate("yyyy-MM-dd hh:mm:ss.S"); // Ví dụ: tw.local.date = new TWDate("2019-7-3 13:20:00.000"); // Cách 2: tw.local.date = new Date(date); // Ví dụ: tw.local.date1 = new TWDate("2019-7-3 13:20:00.000"); tw.local.date = new Date(tw.local.date1); // Cách 3: tw.local.date = new Date(year, month, day, hours, minutes, seconds, milliseco...

BPM WebSphere - Create Datasource (Connect to DB via JDBC)

Bởi -
Hình ảnh
I. Giới thiệu WebSphere là một application server mạnh mẽ của IBM cung cấp cho chúng ta nhiều chức năng có thể config trên giao diện người dùng (UI). Trong bài này sẽ hướng dẫn cách config đến một database thông qua jdbc url. II. Hướng dẫn Truy cập giao diện console WebSphere, từ menu trái truy cập theo thứ tự sau: 1. Thêm authentication 1.1 Security -> Global security 1.2 Java Authentication and Authorization Service -> J2C authentication data 1.3 Click chọn New để tạo thông tin authen đến DB 2. Config Datasource 2.1 Resources -> JDBC -> Data sources 2.2 Click chọn New và nhập các thông tin Data source name : Tên data source JNDI name : Tên jndi (tên này sẽ sử dụng để truyền input vào service SQL trong toolkit System Data) Chọn Next 2.3 Chọn JDBC provider tương ứng với DB cần connect (tạo mới hoặc chọn những provider sẵn có) ...
