Hi,

I read all the posts here and try to solve problem occurred when running the default application created by the following sequence.

grails create-app test
cd test
grails uninstall-plugin hibernate
grails install-plugin app-engine
grails create-domain-class com.test.User
grails install-plugin hibernate
grails generate-all com.test.User
grails uninstall-plugin hibernate
grails app-engine run

Question 1: I selected JPA when installing app-engine, but this line
"Configuring JDO for AppEngine"
appeared in the output after I ran "grails app-engine run".
Is this a bug?

Question 2: Now the last line of the output says open the browser and goto
"http://localhost:8080/"

When I do that, the browser page shows "Grails Runtime Exception"

and the windows console shows a bunch of exceptions, here is some of it.
WARNING: EXCEPTION

I am using Grails 1.1.1 and app-engine-0.8.3.
I just want to make the default application with views running on my local windows. I had a success without view created.

Can someone show a simple tutorial to do that?

Thanks,
gapes

Hi Grocher,

I am working on web app slowly at my spare time. Right now I am using grails 1.04 mySql running on Ubuntu 8.10. This project is still at its early stage and expected to launch in about one year. Now since grails 1.1.1 starts to support google app engine, I am very excited about what you did and thinking about to make a move.

Would you please give me some advices if I should make the move?

Thanks,
Bendanpa

Thomas – heh.. thanks for the instructions for the workaround.
Now, to the real issue..
Could we somehow, slowdown releases? I mean, it seems that right now there is a mad rush to be able to twitter "we did it!" when in fact.. as Thomas's post indicates.. that actual solution is very very far from done.

Grails, to me, is this massive performance enhancing tool.. and right now, it seems like it is 20 hours a week, late at night, moving sideways and not forward at all

Very nice work!

The thing is, I finally started to "get" Python and I created a mashup with it (http://my-favorite-places.appspot.com/). The day I gave a demo about it at work, the AppEngine Java SDK was released, so learning Python wasn't really necessary (but a nice addition to my knowledge anyway).

Today I converted the app to Grails, which you can see here:
http://favorite-places.appspot.com/

I also had the problem with target/war/WEB-INF/datastore-indexes.xml which needs to be removed before uploading to AppEngine.
