Hacked together a version of ZOracleDA based on some old code and a little insight. Result: Oracle works with our Zope install here, and Zope can potentially gain a foothold over Oracle's really, really crappy web app server (which I am convinced is not a result of it being based on Apache Jserv, but is more likely just incompetence at Oracle.)
Along those lines, Java on OpenBSD made some pretty good progress but I seem to be up against a brick wall now. ELF vs. a.out issues are pretty easy to patch. A ream of assembly code that results in "invalid opcode" is not.
