While you can't access ServerRuntime, you can inject anything inside it into
your factory just by declaring and annotating it it ("anything" == interfaces
declared in ServerModule). E.g.:
public class MyDSF implement DataSourceFactory {
@Inject
private DbAdapter adapter;
public DataSource getDataSource(DataNodeDescriptor nodeDescriptor) throws
Exception { .. }
}

While there are other ways to do it, here is a very simple one - create an
instance of DataSourceFactory yourself inside the module, with all the
parameters and pass it to Cayenne DI after that:
public MyM implements Module {
private String[] stuff;
public MyM(String… stuff) {
this.stuff = stuff;
}
public void configure(Binder binder) {
DataSourceFactory dsf = new MyOtherDSF(stuff);
binder.bind(DataSourceFactory.class).toInstance(dsf);
}
}
BTW the above is even compatible with @Inject - Cayenne will inject objects
into fields annotated with @Inject like in the previous example.
