Hi there

I have a situation I'm completely stuck on. I'm creating some POJOs for
use in conjunction with Hibernate. Now some of my POJOs have class
(static) variables that contain shared configuartion information. For
example:

class Car
{
    // example picture of a car
    public static String pictureUrl;

    // model and age of this car
    private String model;
    private int age;

    public Car(String model, int age)
    {
        this.model = model;
        this.age = age;
    }

    // getters/setters etc...
}

Car.pictureUrl = "http://url/to/shared/car/picture.jpg";
Car c = new Car("Model", 5);

//... do a bunch of stuff

Car.pictureUrl = "http://url/to/new/shared/car/picture.jpg";

I want to persist my newly created Car, c, along with the shared class
variable Car.pictureUrl. My question is there any way to tell Hibernate
to persist Car.pictureUrl?

The reason I want to do this is that I want to be able to update class
variables *at runtime*, and somehow persist them so the new value gets
used when the application is restarted. Normally I would hard-code
class variables in my POJO, but I want to be able to update them at
runtime (having the change immediately reflected in all parts of my
app), and have the new values persisted over application restarts, all
without re-compiling the application.

Has anyone had the need to do something like this before? What strategy
should I use? Ideally I'd like to use a database to store the class
variable values and have them populated on application start.

Am I going about this the wrong way?

Any comments would be greatly appreciated!

Thanks
