Joget Cluster Tutorial

Joget Workflow is an open source building platform with a wide range of the tools. It enables you to easily create full-fledged enterprise web applications for the cloud and mobile. Also it is a rapid application development platform with the complete agile development capabilities, such as consisting of processes, drag-and-drop forms, lists, extension via plugins, CRUD and UI elements, not just back-end EAI/integration/task-based or orchestration interface.

With the developed Joget plugin architecture you can easily extend and integrate the platform with other systems.

Joget provides developers with the following capabilities:

building not just processes, but apps
increasing productivity and efficiency of your application
comfortable work with a user-friendly GUI
reducing the cost of training for employees

To get the highly-available and reliable clustered Joget environment in the platform follow the instruction below.

Create Environment

1. Log in to the platform dashboard and click Create environment.

2. In the opened environment topology wizard choose your Java app server (e.g. Tomcat) and obligatory switch on High-Availability to pair up your application instances.

Pick up the database you want to work with (for example, MySQL). Specify the amount of resources for each node within cloudlet sliders.

3. After that specify the name for your new environment (e.g. joget-cluster) and press the Create button at the bottom of the wizard.

Configure Database

1. Open phpMyAdmin panel for the MySQL node by clicking Open in Browser button next to it in your environment. Log in using credentials the platform has sent you after adding the DB node to the environment.

2. Create the new jwdb database for your Joget cluster.

3. Navigate to the Query window and import there jwdb-empty.sql file (it is located in joget-enterprise-linux-x.x.x/data folder of the extracted package) according to your needs. All the necessary tables will be created.

Configure Joget

1. Go back to the platform dashboard and click the Config button for your servlet container (Tomcat in our case).

2. In the opened config manager navigate to the app_datasource-default.properties file in the home/wflow folder and specify there the properties for the database connection using the code below as an example:

workflowDriver=com.mysql.jdbc.Driver  
workflowUrl=jdbc\:mysql\:mysql-{your_environment_name}.{hoster's_domain}:3306/jwdb?characterEncoding\=UTF-8  
workflowUser=root  
profileName=  
workflowPassword={your_database_password}  
hibernate.dialect=org.hibernate.dialect.MySQLDialect

Joget database connection

3. Finally, click Save button and restart your server.

Run Joget

Now you have your own Joget cluster in the platform.

Open the jw context in a web browser to see the Joget welcome page. To start working with it log in with the default credentials (admin/admin).
