jBPM Migration Tool - No one is left behind
0 likes2,530 views
This document discusses a jBPM migration tool that aims to help users migrate their jBPM 3.x and 4.x projects to jBPM 5.x. It provides background on previous versions of jBPM, discusses common challenges with migrating large enterprise projects, and gives an overview of the status and approach being taken with the migration tool project. The tool uses XSLT transformations to convert jPDL files to BPMN, taking a pragmatic approach when exact conceptual mappings are difficult. It has been tested on several sample projects. References are provided for more information on jBPM roadmaps, migration strategies, and the tool project.

- 3. Are you in a rush? Here is a quickie...
- 4. You put your faith in jBPM for your processes...
- 5. ...help us by ensuring you position projects with best practices...
- 6. ...and we have a good shot at tooling your migration to a bright future with jBPM!
- 7. Agenda Where are my jBPM projects now? Migration complexities in the enterprise Status jBPM Migration Tool project Does it work?
- 8. 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 • Feb 2010 to Feb 2015 – SOA-P 5.1 scheduled released Q4 2010 • will contain jBPM 3.2.x == support 2013! – tried, trusted, proven, rock solid enterprise component!
- 9. jBPM 4.x • Community only version of jBPM – jBPM 4.x releases community run – no product – no support – migration to jBPM 5 == community • or maybe we get around to it...
- 10. jBPM 5.x • The future of jBPM – RFC online • leverage existing Drools project • leverage PVM ?= jBPM 4.x – roadmap available online – released into the community 2010 – will become part of JBoss products
- 11. Agenda Where are my jBPM projects now? Migration complexities in the enterprise Status jBPM Migration Tool project Does it work?
- 12. We have been architecting, implementing and deploying jBPM solutions in the strangest places for years now...
- 13. But wait a minute...
- 14. What about us... jPDL != BPMN
- 16. Process implementation • Java handlers – do you keep it clean? • atomic unit of action per process step • human task / admin interfaces • exception handling (jump-to) • custom jBPM DB access • Centralize you jBPM API access – single WS / DAO / BOM – migration made easy (or easier)?
- 17. SOA interaction • Gateway to the Enterprise – Web Services, EJB, GUI, POJO, Exceptions, Bean Script, Rules... • jBPM API & jBPM DB • history / tasks / reporting – single DAO – single Web Service – externalize rules calls in Web Service(s)
- 18. Some best practices... • Simplify everything (KISS) – apply OO to process design • methods == sub-flows + context in/out • encapsulate == sub-flows • reuse == PAR repo (maven potential) • unit testing == per node, sub-flow, flow • keep it all visible (transitions for travel only) • exception handling (Exception Framework)

- 20. What are we up to? • Tooling targets – jPDL 3.2.x to BPMN 2 (CLI) – community welcome for jBPM 4.x – working with use cases • send us projects • raise issues – jBPM 3.x API mapping
- 21. Look under the hood • Research phase – jaxb, smooks, XSLT • Based on main style sheet – jpdl2-bpmn2.xsl – modular setup – positioning ignored (gpd.xml) – large test setup in project • See github wiki for setup
- 23. More cases filled the gaps... jpdl2bpmn
- 25. Conceptual or Pragmatic? • Ideally map concepts – node/state: scriptTask – decision: gateway • Which gateway? – complex, parallel, inclusive... • Event/Action spoilers – running java code in handlers – answer: Java Node!
- 26. Pragmatic choices... part I jpdl2bpmn
- 27. Pragmatic choices... part II Add a gateway, but changes the process? jpdl2bpmn
- 28. Pragmatic choices... part III ????? jpdl2bpmn
