Defining Kie Base using API
To define Kie Base using API, use the following code:
import org.kie.api.KieServices;
import org.kie.api.builder.KieRepository;
import org.kie.api.builder.KieFileSystem;
import org.kie.api.builder.KieBuilder;
import org.kie.api.runtime.KieContainer;
import org.kie.api.KieBase;
...
KieServices kServices = KieServices.Factory.get();
KieRepository kRepository = kServices.getRepository();
KieFileSystem kFileSystem = kServices.newKieFileSystem();
kFileSystem.write(ResourceFactory.newClassPathResource("MyProcess.bpmn"));
KieBuilder kBuilder = kServices.newKieBuilder(kFileSystem);
kBuilder.buildAll();
KieContainer kContainer = kServices.newKieContainer(kRepository.getDefaultReleaseId());
KieBase kBase = kContainer.getKieBase();
