google map widgetsets

hi, i have downloaded the jar and i compile the widgetsets and run my vaadin projects, an error msg has been appeared : Widgetset ‘com.example.myWidgesett’ does not contain implementation for com.vaadin.tapio.googlemaps.GoogleMap. Check its component connector’s @Connect mapping, widgetsets GWT module description file and re-compile your widgetset…
i added manualy “” i 've got this error : Unexpected exception while processing element ‘inherits’
java.lang.NullPointerException.
note that i’m not use maven.
please advise as soon as possible.

You typed in the post ‘com.example.myWidgesett’ with two letter ‘t’ at the end. Maybe a typo in @Widgetset annotation or your custom widgetset is not in the right directory?
