Making a session in swing

[sandor]

This might be a little hard to comprehend but I want to query a database and get an object and then put that object in the 'session' so that all my screens have access to it and can work on it. For instance if I get a list of items, I might want it available to a number of of other little popup screens.
Any ideas?

As far as i understood your problem: Why don't you create a class to hold you data and pass reference of the object created from that class between your dialogs?

NOt sure this is what you want but I usually make a singleton class called Application State. Then I control what is in it with methods such as below.

Code:

 public Object getItem(String key)
    {
        return stateItems.get(key);
    }

    public void setItem(String key, Object item)
    {
        stateItems.put(key, item);
    }

    public void removeItem(String item)
    {
        stateItems.remove(item);

    }

    public void cleanUp()
    {
        stateItems.clear();
    }

It is not configured for java 5.0. This is old code, but you can update. I think I got it from the pet shop example on Sun.
Hope this helps.

That is a good example. I meant something like that.
