I have a GWT app I was building using a 1.6 JDK. However, the place
where I want to deploy it only has Tomcat 5, running jdk 1.5. So I
changed my compiler settings to 1.5 compliance, and a 1.5 jdk, and
rebuild. After I got rid of all my @Override annotations, it
compiled.
If I zip up my war directory into a .war file, it runs on their
Tomcat, and on mine (which is Tomcat 6). However, when I try to load
my app using the built-in Jetty, it fails in onModuleLoad, executing
the follow command (gMainDock is a ScrollPanel) (I'm in Quirks mode,
if that matters):
RootLayoutPanel.get ().add (gMainDock);

Any suggestions on what's going wrong, and how to fix it, would be
greatly appreciated.
TIA,
