Root cause in your error: [ERROR] Line 56: No source code is available for type com.atos.db.DBUtil; did you forget to inherit a required module?
The GWT compiler does not see com.atos.db.DBUtil.java as its not in your client package but is used by any of your client classes. Either move the class into the client package or make the file visible to the GWT compiler through your module.gwt.xml file (add a <source> tag). If this file contains JDBC utility code then re-think what you are trying to do. A web browser can't open a direct JDBC connection to your database. -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
