JSF ActionEvent processAction duplication

[Piter Smith]

For the forward and back links I want to use ActionListener even if it's not quite correct to do so, just so I can understand how to use this class. The two listeners are basically identical, except for the boolean value. How can have make just one listener? Presumably the ActionEvent object has sufficient information to determine that?

and the action, which is duplicated by a ForwardListener which just sends a different value for the boolean:

package net.bounceme.dur.listeners;

import java.util.logging.Logger;
import javax.faces.event.AbortProcessingException;
import javax.faces.event.ActionEvent;
import javax.faces.event.ActionListener;
import net.bounceme.dur.nntp.SingletonNNTP;

public class BackListener implements ActionListener {

    private static final long serialVersionUID = 1L;
    private static final Logger LOG = Logger.getLogger(BackListener.class.getName());

    @Override
    public void processAction(ActionEvent event) throws AbortProcessingException {
        try {
            LOG.info("BackListener.processAction..." + event.toString());
            SingletonNNTP nntp = SingletonNNTP.INSTANCE;
            nntp.page(true);
        } catch (Exception ex) {
            LOG.severe("..BackListener.processAction would not execute " + ex.getMessage());
        }
        LOG.info("..BackListener.processAction");
    }
}

We don't have many rules here at the JavaRanch, but we do insist that you use your Real Name and not some sort of "handle" or obvious alias. If you're not sure about this, see

A little incentive: The sooner you correct your display name, the sooner you get an answer.

Sure you didn't mean "Piter DeVries"?

Well, the name was approved. Oh well, what sort of reply do you want here?
