Thank you for your comment, though, I couldn't find the context menu you
mentioned(Convert project to GWT project) on Project Explorer view in
Eclipse 3.6 with GAE 1.4 plugin. And I believe some of demos are not GWT
based example, they only use GAE.
Though I have succeeded in compiling "helloorm" example somehow.( compile
error was there - "couldn't resolve ..... import
javax.jdo.PersistenceManager;")
But when I launched the "helloorm" example with Ant "runserver" and tried to
access localhost:8080 on my Chrome web browser and I get the error messages
below
HTTP ERROR 500
Problem accessing /. Reason:

I'm wondering if the demos in GAE 1.4 release are working or not.
Oh, and I found only "guestbook" demo works fine with Ant build.xml file
configuration which is useless because I've gone through it with the
tutorial.
