I hope the following code helps you:

            ProcessEngineConfiguration processEngineConfiguration = StandaloneInMemProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration();
            ClassLoader classLoaderBefore = processEngineConfiguration.getClassLoader();
            try {
                processEngineConfiguration.setClassLoader(Thread.currentThread().getContextClassLoader());
            } finally {
            }
            ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
            RepositoryService repositoryService = processEngine.getRepositoryService();
            RuntimeService runtimeService = processEngine.getRuntimeService();
            Deployment deploy = null;
            try {
                deploy = repositoryService.createDeployment()
                        .addInputStream("THE_BPMN_FILE.bpmn20.xml", new FileInputStream(new File ("C:\\THE_BPMN_FILE.bpmn20.xml")))
                        .deploy();
                String procId = runtimeService.startProcessInstanceByKey("THE_PROCESSID_IN_XML_FILE").getId();

            } catch (FileNotFoundException e1) {
                e1.printStackTrace();
            } catch (IOException e2) {
                e2.printStackTrace();
            }
