Presentation given at JFall 2010 (Dutch Java User Group).

SNS Bank is a leading provider of on-line internet banking products within the Dutch financial market. The last three years she has been converting her activities from a traditional branch offices to an on-line experience. This transition has involved extensive business process implementations to put both internal service processes, external service processes as well as product selling channels on-line.

An important part of their processes has always been connected to human tasks, as the financial world often requires human validation / intervention at crucial points in the various processes. To facilitate BPM human tasks SNS Bank has implemented various jBPM GUI solutions. These solutions have led to some important lessons when interacting with jBPM that we will present.

These lessons have led to the In2Flow application provides this session with a great example of how to interact in your jBPM processes using human tasks. This implementation will be discussed and includes SEAM, JBoss Cache, Rich Faces, JBoss WS and all of the best practices to modularize your human task development in future projects.

The lead developer of the In2Flow application will detail the architecture and cover the most important points that you need to be aware of to develop a scalable, flexible, extensible jBPM human task solution for your next jBPM project. This will include an overview of the management information and empirical data that is collected on the human tasks processed within In2Flow, based on four months in a production environment.

      • Monoliet
      • Business wilde andere manier van werken
      • Performance issues i.v.m. aanvraagmodel
      • Onnodig groot complex model
      • (J)BPM Schaduwboekhouding
    • In2Flow - Opdracht
      Maak een webapplicatie waarmee gebruikers
      op een taak-georiënteerde manier kunnen werken
      die makkelijk uitbreidbaar is zonder gebruik te
      maken van een generiek aanvraagmodel.

    • In2Flow – Modulair ontwerp
      In2Flow bestaat uit 1 hoofdmodule waarin
      taakmodules dynamisch(at runtime) kunnen
      worden toegevoegd.
      Een taakmodule bevat 1 of meerdere taakschermen.
    • In2Flow – Modulair ontwerp
      • Doorbreken monoliet
      • Parallelle ontwikkeling eenvoudiger
      • Minder integratietesten
      • Scope is beperkt; minder complexiteit
    • In2Flow – Modulair ontwerp
    • In2Flow – Shared Session
      publicclassSharedSession {
              privateTreeCacheMBean cache;
              publicSharedSession() {
                      MBeanServer server = MBeanServerLocator.locateJBoss();
                      cache = (TreeCacheMBean) MBeanProxyExt.create(TreeCacheMBean.class, "jboss.cache:service=in2flow", server);
              public Object get(finalStringfullyQualifiedName, finalStringattribute) {
                      returncache.get(fullyQualifiedName, attribute);
              publicvoid put(finalStringfullyQualifiedName, finalStringattribute, final Object value) {
