It turns out that the RC4 war file described below is a known bug in grails 1.0-RC4 (wish I'd have known about it) and so I've reverted to RC3 for now. What a pain.
I couldn't deploy the WebTestApp as a war to tomcat (RH Linux, jdk 1.5.0_06) because it failed upon app invocation. The app deployed and appeared to be started in the tomcat administrator, but would not run. I did an experiment and this problem is apparently because of a bug in grails-1.0-RC4.
I therefore did an experiment: I created 4 identical grails apps with 1 domain class and used "generate-all" to generate the controller and views. The only difference between each one, was I created each one in a different version of grails from RC1..RC4.
Basically...
for each grails version X from RC1..RC4
grails create-app testRCX
cd testRCX
grails create-domain-class User
grails generate-all User
grails -Dserver.port=9090 run-app
test
grails war
copy the war file to the tomcat instance and test.
The only one that didn't deploy to tomcat and work was the app for RC4. Tomcat indicated it was started, but when I tried to invoke it, catalina.out reported
java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String
Here's the top of the error:
[4894343] [/testRC4].[gsp] Servlet.service() for servlet gsp threw exception

The rest of the apps ran fine on tomcat.
