hi, i try to populate dropdownlist on gwt ui with data from tables in oracle database, and i have an URI has an authority component exception, can't understand what does it mean? I created service and serviceAsync interfaces with method wich i implement in ServiceImpl in server package to get data from table from db, and there i make a query with db connection. And then on client application i call this method for getting data from table with callback on success. Is it right way to get the data from db table and fill with it an dropdownlist on gwt ui? Any suggestions?
