Answer 1

You need to check all your interfaces which extends RemoteService and have declared a RemoteServiceRelativePath annotation, ensure that all such relative paths get mapped in web.xml
Example - in https://developers.google.com/web-toolkit/doc/latest/tutorial/RPC
#RemoteServiceRelativePath("stockPrices")
public interface StockPriceService extends RemoteService {
}
gets mapped to
<!-- Servlets -->
<servlet>
<servlet-name>stockPriceServiceImpl</servlet-name>
<servlet-class>com.google.gwt.sample.stockwatcher.server.StockPriceServiceImpl</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>stockPriceServiceImpl</servlet-name>
<url-pattern>/stockwatcher/stockPrices</url-pattern>
</servlet-mapping>
