I got a similar error when having jasper reports and jdtcompiler jars in war/WEB-INF/lib. I could solve it by changing classpath ordering in the gwt web application run configuration. Go to your run configuration -> classpath, delete all User Entries (you can not re-order the default user entries) and then add:
1.) src folder of your project 2.) Your project 3.) GWT SDK 4.) Webapp Libs 5.) Server Runtime Make sure that GWT SDK is before your webapp libs. That way the gwt compiler will use the correct jdt compiler files and not the one provided through your webapp libs. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
