Hola Ken!
I have a couple of questions about this:

* Would I be better off doing [3] as a Cocoa/Java app? I've never done Cocoa/Java yet, only Cocoa/Obj-C, and Pure Java.

You may try Cocoa/EO... it is an unsupported tech but it works. It lets you use the best of both worlds ---use EOF writing in ObjC and with Cocoa on top of it.
Take a look to http://www.wodev.com under the link CocoaEOApplication. You will find there some usefull hints.



* Would doing at least the database-y bits of [3] in Java give me advantages, such as the ability to talk to the WO server, rather than talk directly to Postgres? This way WO (or rather EOF) could be doing the database logic, rather than me have to worry about the JDBC (or ODBC in Objective-C) and SQL logic. Bearing in mind I'm a WO newbie, would this give me benefits do you reckon? FYI the Postgres and WebObjects servers are the very same Xserve.

Definitly. Let EOF do the work for you!


* Would I be better getting WO to link to both the Postgres database *and* the Oracle database (which both contain different info), or should I channel WO -> Postgres -> Oracle? Which is less work, and would there be any speed advantage?

You can have as many databases under the same app. Take a look to Chapter 10 of "Inside Web Objects: Enterprise Objects".



* Can WO fire up an Obj-C Cocoa app (that's also on the server)?

I don't think so, but never tried... what you can do is to "publish" a downlodable Cocoa/EO app in a WO page, but I dont see here any adventage in WO over static html (unless you want to restrict the access via a login or some other mechanism).


Hope it helps.


Thanks in advance for any wisdom you can give, Ken
