@ASTX813

The JDO persistence manager handles setting and getting via the getter and setter methods.

As for creating the Object from the fields, you need to set the files one by one.

Thanks for appreciating my site, I was not able to update it anymore, although I'm still trying to experiment on some android app when I get some spare time.

Thanks

I notice in your Beer class, you don't have a constructor. How are you creating & setting the id field? Is that being handled by the persistence manager since it is tagged as the primary key?

Great writeup, I'm following your tutorial project, and so far it has been the most helpful information I've found since I've started learning Android!

Hi Winai,

There's something wrong with your code. It's not an app engine problem anymore.

If you are using eclipse, try just creating a simple project without GWT.

You should have a hello world servlet working. Then work from there.

2009-07-29T10:43:02.832+08:00

Hi Winai,

"class file has wrong version 50.0, should be 49.0"

You may have the wrong JDK version. Kindly check if your are using Java 1.5 or use 1.6 if it still does not work.

Type "java -version" on the command line

If that does not work, maybe the AppEngine version you are using is an older version. Upgrade to a newer one.

I cannot remember getting this problem before, but I also encountered a compile/build problem when I upgraded to AppEngine SDK 1.2.2, I just right click on the project, then properties, then expanded the Google tree menu, then selected the App Engine entry. Then chose App Engine SDK 1.2.2.

Hi Winai,

Can you give me more details of your problem?

Are you using the eclipse plug-in? Can you post some exceptions / error messages you are getting?

Hi Tamas,

I'm thinking of including a key in the HTTP header that identifies the request is coming from an android phone.

I'll just post my solution when I'll have time.

Thanks a lot.

Hi there, Do you have any idea on how to move on?...

2009-04-15T03:10:00.000+08:00

Hi there,

Do you have any idea on how to move on?

I have a similar project in my mind. Done the same with App Engine for Java, but having problem in finding a suitable but yet secure way of attaching Android as client to the App Engine application as a server.

I come from the world of WS and it is hard to imagine how to move on without it. :)

Best Regards,
Tamas
