Yeah, the Wiki page refers to Cayenne 3.0 and earlier. In 3.1 it is much easier
and can be done via a DI container. And you don't have to remember all the
classes that might use the DataSource. So you would create a custom module,
bind a custom DataSourceFactory, and pass it to ServerRuntime constructor:
Module m = new Module() {
public void configure(Binder binder) {
binder.bind(DataSourceFactory.class).to(MyDataSourceFactory.class);
}
};
ServerRuntime r = new ServerRuntime("cayenne-myconfig.xml", m);
