[appengine-java] Can an Integer be a primary key for JDO?

I was just wondering whether I could use an Integer for a primary key in JDO, as it would be a great convenience in my application. I couldn't really find an answer to this in the documentation, so I ask you. Can I? -- You received this message because you are subscribed to the Google Groups

[appengine-java] Re: JDO analogue of GQL

I found what was wrong. It is a really good reason never to use deprecated API anymore. 2009-12-1 is new Date(109, 11, 1); But not new Date(2009,12,1) or new Date(9,12,1) or new Date(109,12,1) On Jan 16, 2:17 pm, Max max.seven@gmail.com wrote: I just seen that my last code is working!

I mentioned Resteasy in your other thread, but you might also want to consider Hessian. I recently patched the Caucho impl and now both client server work on GAE (we use Hessian for server-server RPC, and JAX-RS to the phones). If you're creating internal protocols, Hessian is way easier than

You cannot create a data model in JDO-GAE that is agnostic of its environment. Twig allows your domains classes to use any key type you want or even none at all. class Parent { String name; @Entity(relation=child) Child child; } class Child { String name; } This will be correctly

Isn't there any other way. I want to avoid toLowerCase(). I want String to be case insensitive for database, but while displaying String to user I would like it to conserve case.. I can compare strings through equalsIgnoreCase. But then I won't be able to make effective use of primary key. On
