Bernard,

Thanks for you feedback. I just tried your suggestion: I created a D2W application with two entities

Department <------------>> Person

The database is in MySQL. Application runs normally in development mode.

Target Setting for Servlets:
SERVLET_COPY_JARS                               YES
SERVLET_DEPLOY_LICENSE          <my license>
SERVLET_SINGLE_DIR_DEPLOY               YES
SERVLET_TRUE_WAR                                NO
SERVLET_WEBAPPS_DIR                     /Library/Tomcat/webapps

Here is the result of the test by accessing the deployed application in a browser: http://myhost:9006/MyApp/WebObjects/MyApp.woa

-----------------------------------------------------------
Error:
com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException: [ valueForKey()]: lookup of unknown key: 'username'. This WOComponent does not have an instance variable of the name username or _username, nor a method of the name username, _username, getUsername, or _getUsername
-----------------------------------------------------------

Hence reaffirming my original assumption that WOComponent binding are not functioning at all in Tomcat deployment under the following server configuration:

Mac OS X Server 10.4.8 (Tiger)
Java SE 5.0
Tomcat 4.1
MySQL 4.1.13

Tomcat launch script output:
Using CATALINA_BASE:   /Library/Tomcat
Using CATALINA_HOME:   /Library/Tomcat
Using CATALINA_TMPDIR: /Library/Tomcat/temp
Using JAVA_HOME: /System/Library/Frameworks/JavaVM.framework/ Versions/1.4/Home

Development box configuration:
Mac OS X 10.4.8 (Tiger)
Xcode 2.4 (with WO installed at Xcode install)

I've had WO apps working on Tomcat 4.x running on OS X, Windows, and even OS/2. So, mostly it does just work. One thing is that I've always used SSDD.

Can you try producing a D2W app and deploying that as a Tomcat app? That should tell you if it is something intrinsically wrong with display groups in WO/Tomcat or if it is something in your particular app that is causing this exception to be thrown.
