The document details the migration strategies for transitioning from jBPM 3.x and 4.x to jBPM 5, emphasizing best practices for process initialization, definition, and implementation. It discusses tools for converting jpdl to bpmn2 and highlights the importance of simplifying processes while adopting an object-oriented approach. Various resources and links are provided for further guidance on jBPM migration and implementation strategies.

- 3. Agenda Where are we with jBPM{3|4|5} Enterprise usage of jBPM Migration strategy for Enterprise jBPM
- 4. jBPM 3.x The first productized version of jBPM jBPM 3.2 Sep 2007 to Sep 2013 latest SOA-P 5 == jBPM 3.2.6
- 5. Feb 2010 to Feb 2015 SOA-P 5.1 scheduled released Q4 2010 will contain jBPM 3.2.x == support 2015! tried, trusted, proven, rock solid enterprise component!
- 6. jBPM 4.x Community only version of jBPM jBPM 4.0 start of new PVM
- 7. jBPM 4.4 release community run
- 8. will never make it to product or support
- 9. future migration to jBPM 5 == community
- 10. jBPM 5.x The future of jBPM RFC online leverage existing Drools project
- 11. leverage PVM ?= jBPM 4.x roadmap available online
- 12. first community release 2010 @JUDCon!
- 13. will become part of JBoss products
- 15. Agenda Where are we with jBPM{3|4|5} Enterprise usage of jBPM Migration strategy for Enterprise jBPM
- 16. We have been architecting, implementing and deploying jBPM solutions in the strangest places for years now...
- 17. But wait a minute...
- 18. What about us... jPDL != BPMN
- 19. Agenda Where are we with jBPM{3|4|5} Enterprise usage of jBPM Migration strategy for Enterprise jBPM
- 21. Some focus areas Process initialization layer
- 25. General best practices for positioning your projects
- 26. Process initialization How do you start your process? web services, EJB's, API call
- 27. what about prioritization of processes use message queues
- 28. other complex ideas to start processes API to startProcess changes... centralize startProcess in single location minimizes change effects in this layer
- 29. Process definition Just process definition files imagine a right-mouse to 'convert' jPDL to BPMN2 migration tooling project jPDL 3.2.x to BPMN 2 (CLI)
- 30. jBPM 3.2.x API mapping to jBPM 5
- 31. Process implementation Java handlers do you keep it clean? single unit of action per process step
- 32. human task / admin interfaces
- 34. custom jBPM DB access Centralize you jBPM API access single WS / DAO / BOM
- 35. migration made easy (or easier)?
- 36. SOA interaction Processes interact with your Enterprise Web Services, EJB, GUI, POJO, Exceptions, Bean Script, Rules... jBPM API & jBPM DB
- 37. history / tasks / reporting single DAO
- 39. externalize rules calls in Web Service(s)
- 40. Some best practices... Simplify everything (KISS) apply OO to process design methods == sub-flows + context in/out
- 42. reuse == PAR repo (maven potential)
- 43. unit testing == per node, sub-flow, flow
- 44. keep it all visible (transitions for travel only)
- 45. exception handling (Exception Framework)
- 46. Migration tool project What needs to be done: jPDL 3.2.x to BPMN 2 (CLI)
- 47. jBPM 3.2.x API mapping to jBPM 5
- 48. community welcome for jBPM 4.x
- 49. working with use cases start simple
- 50. send us projects / raise issues. TODO: wiki, jira, etc.
