How to pass a custom resource to custom resource factory?

[daveg-iwd <da...@iwd.iowa.gov>]

I have a 3rd party library I can potentially define to tomee as a resource
created by a factory class.  But the constructor for the resource factory
only takes a specific class. Something like this:

public class Config {
   String opt1;
   String opt2;
   public setOpt1(String s) { opt1 = s; }
   public setOpt2(String s) { opt2 = s;  }
   public String getOpt1() { return opt1; }
   public String getOpt2() { return opt2; }
}

public class TheFactory() {
    private Config conf;
    public TheFactory(Config c) { this.conf = c }
    public Object makeObject() { return .... }
}

I figure I'd define the Config in tomee.xml as 

  <Resource id="aconfig" class-name="Config">
     opt1 blah
     opt2 derp
  </Resource>

The question is if there is a way to tell the resource definition for the
factory that the input to its constructor is the "aconfig" resource?

I thought it might be something like

<Resource id="afactory" class-name="TheFactory"
                    factory-name="makeObject" constructor="what to put
here?">
      config iwdldap
</Resource>

Is this possible or might I have to make my own factory that would use
Properties instead?

(didnt tested but sharing the idea)

  <Resource id="aconfig" class-name="Config">
     opt1 blah
     opt2 derp
  </Resource>
<Resource id="afactory" class-name="TheFactory"
                    factory-name="makeObject" constructor="config">
      config = @aconfig
</Resource>

Think you can use a Service instea dof resource for aconfig and replace the
@ by $ to link it to the service in the factory.
