Last year at JavaONE Karl told me that Orion supported AJP12. I've tried mod_jk in several ways, tried looking for a place to set an AJP connector in Orion, and even poped open the orion.jar looking for a connector. It never worked - so I gave up many months ago.
Now its becoming more important and I notice that the Oracle 9iAS supports AJP12. What gives? Karl? Magnus? AJP support?
