i had to add serialVersionUID to my wicket pages since they are stored in the session and serialized. I guess they are not required by Eclipse when I create a wicket page. before i did that, i was receiving an exception like:

javax.servlet.ServletException: java.lang.RuntimeException: java.io.InvalidClassException: wicket.LoginPage; local class incompatible: stream classdesc serialVersionUID

I agree that it works fine in Eclipse using the Google appengine plugin, but after deplyoying to Google the first page was ok, but trying to simulate some other pages I get this error: 500 Server error
and the logs is:

Uncaught exception from servlet
com.google.apphosting.api.ApiProxy$RequestTooLargeException: The request to API call datastore_v3.Put() was too large.

any idea?

Really been trying this but can’t get it working in the app engine. It works fine in Eclipse but on Google I get a 404 – so I wonder where the difference is.

Marvelous ! I just read about GAE/J and searched for someone who tried wicket and here you are. Thanks.
I think wicket is perfect for that platform.
Really good news.
thanks
