27.2. Example requests to execute a business process

// Build resource from Process
KieResources resources = ServiceRegistry.getInstance().get(KieResources.class);
Resource res = resources
                        .newByteArrayResource(factory.toBytes(process))
                        .setSourcePath("/tmp/processFactory.bpmn2"); // source path or target path must be set to be added into kbase
// Build kie base from this resource using KIE API
KieServices ks = KieServices.Factory.get();
KieRepository kr = ks.getRepository();
KieFileSystem kfs = ks.newKieFileSystem();
kfs.write(res);
KieBuilder kb = ks.newKieBuilder(kfs);
kb.buildAll(); // kieModule is automatically deployed to KieRepository if successfully built.
KieContainer kContainer = ks.newKieContainer(kr.getDefaultReleaseId());
KieBase kbase = kContainer.getKieBase();
// Create kie session using KieBase
KieSessionConfiguration conf = ...;
Environment env = ....;
KieSession ksession = kbase.newKieSession(conf,env);
// execute process using same process Id that is used to obtain ProcessBuilder instance
ksession.startProcess(processId)
