A.2. Environment Properties
As opposed to system properties, environment properties are passed to an individual KieSession, allowing you to control its behaviour independently on the rest of the deployment.
The properties available to you are the constants of the class org.kie.api.runtime.EnvironmentName.
A.2.1. Configuration
To set the environment properties on a KieSession, you can create a new session with an instance of the Environment or RuntimeEnvironment interface:
Setting Environment Property using Environment interface
Environment env = EnvironmentFactory.newEnvironment();
env.set(EnvironmentName.SAMPLE_PROPERTY, true);
kbase.newKieSession(null, env);Setting Environment Property using RuntimeEnvironment interface
RuntimeEnvironment environment = RuntimeEnvironmentBuilder.Factory.get()
.newDefaultBuilder()
....
environment.getEnvironment().set(EnvironmentName.SAMPLE_PROPERTY, true);
singletonManager = RuntimeManagerFactory.Factory.get().newSingletonRuntimeManager(environment);A.2.2. List of Environment Properties
This section contains the alphabetically sorted list of all recognized environment properties in Red Hat JBoss BPM Suite 6.3.
