Application development process for Google Appengine on Grails

Application development process for Google Appengine on Grails

This is the note I took while watching grocher 's Screen cast from the Grails 1.1.1 announcement
So all honor goes to grocher and the grails/groovy team.

1. grails create-app grails-music-store
2. Goto appengine.google.com, add new application grails-music-store . Note the app name must match
3. cd grails-music-store
4. grails uninstall-plugin hibernate
5. grails install-plugin app-engine
6. export APPENGINE_HOME=/Developer/appengine-java-sdk-1.2.0
7. grails app-engine
then goto 8080 and see the skeleton app
8. grails create-domain-class Album
JDO by default
9. grails generate-all com.music.Album
10. grails app-engine
On Windows, After kill the application, the java process is still running. I have to kill the java process manually. (currports is a nice tool for this process)
11. grails app-engine package
12. /Developer/appengine-java-sdk-1.2.0/bin/appcfg.sh update ./target/war
provide password //first time
It will fail. Fail because of version.
13. grails set-version 1 (This is not the app engine version)
14. do step 11-12 to build and deploy again
/Developer/appengine-java-sdk-1.2.0/bin/appcfg.sh update ./target/war
15. Check it out
http://grails-music-store.appspot.com/album/create (or list...)

Of course you need to install the app engine sdk first.
