Are you using AppEngine? Given you mention Objectify, I am assuming you are.
If that is the case, take a look at using RequestFactory with Objectify. Objectify is much lighter weight than JDO etc (faster startups) - and so many of the posts on the AppEngine developer sites are questions about problems with JDO/JPA. So much easier to use. Also it takes care of a lot of the memcache stuff for you. RequestFactory has advantages over GWT RPC as you can 1/ easily use it with Android devices(using eclipse plugins "Android Connected Web Application feature) 2/ you only use an interfaces on the client - no more worrying about whether your DTO's use classes that can't be used on GWT, Android and AppEngine 3/ it only sends diffs of your updated entities - saving on bandwidth Take a look at this even if you don't do anything with Android - was a real eye opener for me. http://www.youtube.com/watch?v=M7SxNNC429U and also this one on Objectify/Request factory http://turbomanage.wordpress.com/2011/03/25/using-gwt-requestfactory-with-objectify/ On Jun 2, 12:55 pm, "J.Ganesan" <[email protected]> wrote: > You may use the emulated JRE > (http://code.google.com/webtoolkit/doc/latest/RefJreEmulation.html > ) to model relationships.
