Getting the currently active ServerRuntime
Hi all.
I’m writing a Cayenne-based CRUD framework of sorts, in the form of a jar that plugs into Cayenne applications. Currently, I’m telling the framework about the Cayenne environment at application startup by setting a ServerRuntime variable manually in a configuration class. Is there any way for me to smooth out this operation by making the framework automatically obtain the active ServerRuntime in the current environment?
Cheers,

You can add it to a List of project locations inside your Module 'configure':
public void configure(Binder binder) {
binder.bindList(Constants.SERVER_PROJECT_LOCATIONS_LIST).add("cayenne-xyz.xml");
}
Or explicitly pass it to ServerRuntime, when you are creating it.
Though the first approach provides better encapsulation of your framework.

That’s pretty awesome. One question though, how do I tell the Module about the location of it's Cayenne Model? (like I do with the configurationLocation parameter in ServerRuntime)
Thanks!

Hi Hugi,
Are you using DI by any chance in your app? Cause if you do, it becomes as simple as making ServerRuntime one of the "services" and injecting it into your framework.
Or maybe you can invert that? Instead of telling the framework about ServerRuntime, you tell ServerRuntime about your framework (essentially relying on Cayenne to be your DI provider). To do that you expose your framework as a DI Module. That's our preferred way of loading Cayenne extensions. Maybe you can use the same approach with your own code:
// this comes from your framework. The module can define a class that decla
public class MyModule implements Module {
public void configure(Binder binder) {
// MyFrameworkImpl may inject ObjectContextFactory to obtain contexts
binder.bind(MyFramework.class).to(MyFrameworkImpl.class);
}
}
// this is how you bootstrap both Cayenne and your framework in your app
MyModule m = new MyModule();
ServerRuntime runtime = new ServerRuntime("myproject.xml", m);
MyFramework f = runtime.getInjector().getInstance(MyFramework.class);
// now you can call methods on f.

Not really, what we're doing works at a little lower level and serves more specific requirements. Framework looks nice though—and it’s fun to see Cayenne in the wild.

Is there overlap with this: http://nhl.github.io/link-rest/ which was already built over the top of Cayenne?
