JSF

It's been hard to fit in development time around meetings, OMR problem-solving and trying to badger Systems Support to install the server I ordered last September (it's been sitting switched off since it was delivered in November). But I have made progress.

Things I've learnt about JavaServerFaces this week:

  • How to make JSF pass a per-request PersistenceManager to JSF backing beans that need one. I love it when technology makes life this simple!
  • That's it's pretty much impossible to debug JSP scriptlets in pages that are managed by the JSF servlet, at least using Sun's reference implementation. You don't get to see the stack trace, so runtime errors are impossible to diagnose. Conclusion: use zero scriptlet code in JSF pages.
