Eric, thank you for your reply. The thing is that I encounter this issue by trying to work around the Xerces class issue. I had encountered the Xerces class issue with Google GWT Gadget library file described at http://groups.google.com/group/google-appengine-java/browse_frm/thread/145d950d2606bef7/d5c00a71468a08fb?hl=en&q=Gears,+Gadget+API+libraries+giving+error+with+GWT#d5c00a71468a08fb. Thereby, as I wrote, I picked up the gwt-gadgets-noredist.jar from http://gwt-google-apis.googlecode.com/files/gwt-gadgets-1.0.3.tar.gz, which does not contain Xerces classes (And I confirmed that gwt- gadgets-noredist.jar does not contain Xerces classes.) So, I had good expectation of that it would compile without a problem. But.. I got this issue.
