GWTAE first try

I just try the Google AppEngine with GWT. The eclipse plugin is pretty cool and simple to use.

But it's not perfect in:

1. i want to use servlet context listener, but it doesn't support --> use filter to do it instead
2. i want to share my data with other applications but seems it's hard to do that, except I use external database service like Amazon S3
3. i want to add some big file but it has a memory restriction for big files < 1M ....

or i need more tries
