GWT/GAE Spring IoC powered

I'm trying to put together Google App Engine and Google Web Toolkit for one of my projects.

I think I'm going to use Objectify for data persistence, too.

The guys of Springsource says that integrate those technology with Spring is possible.

Do you know where can I find some sort 开发者_JS百科of tutorial about that?

Spring + GAE == slow start up for every instance. You will face performance problems. In my project I had to get get rid of Spring once we had everything implemented :( I wont use Spring + gae anymore

There is no any extra stuff required, no special configurations, tricks, etc. If you know both Spring and GAE - just use it, it's pretty standard.

I've few project based on Spring+GAE+Objectify+Java/Groovy - everything working fine together.

update:

Spring is good only for server-side part. As you want to use IoC on client side (in GWT part), you can use Google GIN instead. It's Google Guice framework (IoC from Google) designed for using with GWT.
