Nothing at the library level has changed in GWT Designer any time recently. The requirements under Linux are (and have been for quite some time) libwebkit.so or xulrunner-1.9.x. GWT Designer tries to use WebKit first. If it isn't available for some reason (older Linux distro or wrong/different library name), GWT Designer tries to fallback to Mozilla and use xulrunner-1.9.x. Keeping up with the incompatibilities between Linux distros and versions is rather mind numbing at times.
Is the GWT Designer bundle com.google.gdt.eclipse.designer.hosted.2_2.webkit installed in your Eclipse environment. If that is not installed for some reason, GWT Designer can't use WebKit, and you would see that same exception. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
