You should probably ask this over at the arsdigita site.
ACS 5, at least, won't be running inside Oracle. I don't think the
Java version of ACS 4 does, either. The java snippets inside the Tcl
version of ACS 4 do, though, and we'll be dealing with that in OpenACS
by rewriting them to use Dan Wickstrom's java module for AOLserver.
Wow, we just had an earthquake as I sat here typing this...aD giving
up Tcl and moving to Java really is earthshaking news, I guess!
