Chapter 4. Business application execution
By default, business applications contain a single runnable project, the service project. You can run the service project on Windows or Linux, in standalone or development (managed) mode. Standalone mode enables you to start your application without additional requirements. Applications started in development mode require Decision Central to be available as the Decision Manager controller.
4.1. Running business applications in standalone mode
Standalone (unmanaged) mode enables you to start your business application without additional requirements.
Prerequisites
-
You have a
<business-application>.zipfile that you created using the business applications website. - The business application is configured.
Procedure
-
Navigate to the
<business-application>/<business-application>-servicefolder. Enter one of the following commands:
Table 4.1. Standalone launch options Command
Description
./launch.sh clean installLaunches in standalone mode on Linux or Unix.
./launch.bat clean installLaunches in standalone mode on Windows.
./launch.sh clean install -PmysqlLaunches in standalone mode on Linux or Unix if you have configured the application with a MySQL database.
./launch.bat clean install -PmysqlLaunches in standalone mode on Windows if you have configured the application with a MySQL database.
./launch.sh clean install -PpostgresLaunches in standalone mode on Linux or Unix if you have configured the application with a postgreSQL database.
./launch.bat clean install -PpostgresLaunches in standalone mode on Windows if you have configured the application with a PostgreSQL database.
The
clean installargument directs Maven to build a fresh installation. The projects are then built in the following order:- Data model
- Business assets
Service
The first time that you run the script, it might take a while to build the project because all dependencies of the project are downloaded. At the end of the build, the application starts.
Enter the following command to access your business application:
http://localhost:8090/
-
Enter the credentials
user/userorkieserver/kieserver1!.
4.2. Running business applications in development mode
Development (managed) mode enables developers to work on a Red Hat Decision Manager business application business assets project and dynamically deploy changes to the business application without the need to restart it. In addition, development mode provides a complete monitoring environment for business automation capabilities, for example process instances, tasks, and jobs.
Prerequisites
-
You have a
<business-application>.zipfile that contains a business assets project, that you created using the business applications website. - You configured the business application.
- Decision Central is installed and running.
Procedure
-
Navigate to the
<business-application>/<business-application>-servicefolder. Enter one of the following commands:
Table 4.2. Managed launch options Command
Description
./launch-dev.sh clean installLaunches in development mode on Linux or Unix.
./launch-dev.bat clean installLaunches in development mode on Windows.
./launch-dev.sh clean install -PmysqlLaunches in development mode on Linux or Unix if you have configured the application with a MySQL database.
./launch-dev.bat clean install -PmysqlLaunches in development mode on Windows if you have configured the application with a MySQL database.
./launch-dev.sh clean install -PpostgresLaunches in development mode on Linux or Unix if you have configured the application with a postgreSQL database.
./launch-dev.bat clean install -PpostgresLaunches in development mode on Windows if you have configured the application with a PostgreSQL database.
The
clean installargument directs Maven to build a fresh installation. The projects are then built in the following order:- Data model
- Business assets
Service
The first time that you run the script, it might take a while to build the project because all dependencies of the project are downloaded. At the end of the build, the application starts.
Enter the following command to access your business application:
http://localhost:8090/
-
Enter the credentials
user/userorkieserver/kieserver1!. After the business application starts, it connects to the Decision Manager controller and is visible in MenuDeploy Execution Servers in Decision Central.
