Out of curiosity have you tried JDO with GAE? Does anyone have a
simple example?

Br's,

 GAE supports JPA and there's a lot of Lift JPA support... so maybe we can
 update the example code to use JPA and we'll have persistence via BigTable.

 In terms of Comet support (which relies on Actor support), I've got some
 ideas on how to make the Actors always use the current thread which will
 mean no spawning threads.  We'll also have to set the default Comet timeout
 to 25 seconds as to not violate the GAE 30 second max request rule.

 Fun stuff to do next week.

 Thanks!

 David

As stated in the Scala list, GAE doesn't support JDBC or Threads.

It does however, support JPA.

Since it only supports the Servlet 2.4 spec currently, it doesn't include
the Continuations as in the 3.0 spec.

This means that for now, I think the odds are against us on this one.

Did I miss something?
Cheers,
Viktor
