Execution of bpmn processes from java code.

[dsouzapreethi]

Is it possible to execute bpmn processes deployed in s-ramp repository from server side code in FSW?

If yes may i know the steps to perform?

The requirement is to trigger bpmn processes using schedular periodically from server.

Thanks in advance

You mentioned that the processes are deployed in S-RAMP. Are these for design-time governance workflows or are they used for service orchestration inside a FSW runtime?

Hi Keith,

Thanks for ur reply.

I am able to resolve this problem with SrampAtomApiClient API.

Here is my code snippet:

private static final String endpoint = "http://localhost:8080/s-ramp-server";

    private static final String user = "test";

    private static final String password = "test@123";

    private static String SRAMP_KIE_JAR_QUERY_FORMAT="/s-ramp/ext/KieJarArchive[" //$NON-NLS-1$

  + "@maven.groupId='%s' and " //$NON-NLS-1$

  + "@maven.artifactId = '%s' and " //$NON-NLS-1$

  + "@maven.version = '%s']"; //$NON-NLS-1$

  SrampAtomApiClient client = new SrampAtomApiClient(endpoint, username, password, true);

  String srampQuery = String.format(SRAMP_KIE_JAR_QUERY_FORMAT, "com.sramp", "srampproj", "1.0");

  QueryResultSet results = client.query(srampQuery);

  ArtifactSummary artifactSummery = results.get(0);

  InputStream is = client.getArtifactContent(artifactSummery);

  KieServices ks = KieServices.Factory.get();

      KieRepository repo = ks.getRepository();

      KieModule kModule = repo.addKieModule(ks.getResources().newInputStreamResource(is));

      KieContainer kContainer = ks.newKieContainer(kModule.getReleaseId());

      KieSession session1=kContainer.newKieSession();

      session1.startProcess("srampproj.samplebpmn");
