I'm getting the same issues. Very frustrating. Something strange isgoing on with the Instantiator code that isn't being politely treatedby the appengine.

I've included tapestry-core, annotations and ioc and other dependent
libraries to the classpath /war/WEB-INF/lib. In my templates I'veused only
a page property and the component PageLink.

Thanks Christian K,

Can you post your GAE application's folder structure (also how you
integrated tapestry jars in it) and if possible the source of thedemo app.I tried 5.0.18 version and I am getting NoClassDefFoundError on aninner
class corelib.components.Loop$1

Thanks,
Sriram Keerthy
