[google-appengine] Re: New bie question: import com.google.appengine cannot be resolved
Thanks Jason,As also pointed out by Shawn that we cannot simply use Key in client code we need write a super class instead. So now i have changed my implementation to use Long instead of key.

I believe the issue here is that the GWT compiler cannot find the source code for the Key class, as detailed in the post at http://fredsa.allen-sauer.com/2009/04/1st-look-at-app-engine-using-jdo.html . You should be able to follow the steps in that post, stubbing out the Key class, to get your application working. - Jason On Fri, May 8, 2009 at 3:04 PM, vijay mymail.vi...@gmail.com wrote: Hi, I am using GWT+ Appengine for building a simple web application and got stuck with a error.
