Re: [appengine-java] Run App Engine on a production intranet
Hi I would suggest you run your application in some load test tool like Apache JMeter to see how the development environment run working as a production environment.

Re: [appengine-java] How to send data back to client side code?
Hi, this is a GWT issue. The model class Employee must implements the com.google.gwt.user.client.rpc.IsSerializable interface in order to be able to be transcripted between server and client.

Re: [appengine-java] How to send data back to client side code?
Ok,
try this, move your class to some place inside /src/client and implement
IsSerializable.
I hope this be enough to solve the problem.
import ContactInfo;
// ... imports ...
@PersistenceCapable
public class Employee *implements
com.google.gwt.user.client.rpc.IsSerializable*{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private ContactInfo myContactInfo;
// ... accessors ...
}
Best Regards,
Alessandro

Re: [appengine-java] Spring or Struts with Google app engine.Is it feasible to use any of these?
Hi, both frameworks are compatible with GAE for Java, (Struts 2 with some workarounds, not much complex). I suggest you to use the framework with which you are accustomed. I have ever used Struts 2, Spring and now I am using GWT (ultimately I have preferred this one), all of them were pretty straightforward to develop.
