Building as a WAR file

Hello, haven't seen much activity here, even though I'm still using  
webobjects...  The lack of activity is a bit worrisome.

Anyway, I am trying to deploy a .war file to a linux machine; I've  
puzzled through a lot of it, but there are a few oddities, and I seem  
to be blocked from going any further.  I edited my xcode build  
settings for deployment to be:
                                 SERVLET_COPY_JARS = YES;
                                 SERVLET_DEPLOY_LICENSE = "blah";
                                 SERVLET_SINGLE_DIR_DEPLOY = YES;
                                 SERVLET_TRUE_WAR = YES;
                                 SERVLET_WEBAPPS_DIR = /Library/ 
WebObjects/WARFiles;
                                 SPLIT_INSTALL = NO;

Then I do an xcodebuild -configuration Deployment.  This creates a  
directory structure under /Library/WebObjects/WARFiles; it does NOT  
create the actual War file.  Scratching my head, I created a 19M war  
file, upload it, and expand it under my tomcat directory.  When I  
bring up the main page, everything works fine; of course, it is  
merely a list of links to other pages.  When I go to another page, I  
get the following output in my catalina.out file:
- An exception occurred while trying to open a channel:  
com.webobjects.jdbcadaptor.JDBCAdaptorException: Cannot create JDBC  
driver of class '' for connect URL 'null'
- <com.webobjects.appserver._private.WOComponentRequestHandler>:  
Exception occurred while handling request:
java.lang.IllegalStateException: _obtainOpenChannel --  
com.webobjects.eoaccess.EODatabaseContext  
com.webobjects.eoaccess.EODatabaseContext@c063ad: failed to open  
database channel.  Check your connection dictionary, and ensure your  
database is correctly configured.

Any guesses what I need to do?  The eomodel is out there, in the  
directory:
appname/WEB-INF/appname.woa/Contents/Resources/mono2.eomodeld

It is intended to connect to Oracle, but I have to guess that it is  
not finding the eomodel for some reason.
