Thanks!  Couple more questions ...

1) Where do I get 3.0? Nightly snapshot? Is any one more stable than any other? Any installation instructions? Or things to watch out for?

# mvn install

Use svn to get a local checkout of the source. Then install maven on your computer and: The product gets put in the world's longest path, somewhere inside ~/.m2/ Just look at the last couple of messages in the maven build.

2) Is the "handleCallback" argument actually the name of the method to call as the callback, aka "myPostPersist"?

That's the idea. We have methods like this in the entities:

protected void prePersist() {
        // do something
}

3) Where is the proper place to set up the callbacks? In a custom data context factory (assuming you always want the callbacks)? This is for a web app using thread data contexts.

Where you initialise Cayenne.

4) Where do I get the domain object?

Configuration.initializeSharedConfiguration();
Configuration conf = Configuration.getSharedConfiguration();
dataDomain = conf.getDomain();


aCallback.addListener( Foo.class, "prePersist" );
