How to develop/debug classes that are integrated in the faces-config.xml?

What is the best way/practice to develop and debug classes which need to be referenced in the faces-config.xml? I've this problem with custom validators and a custom phase listener that should be implemented.

My current approach is to close the Designer and start it again for every debug or development step, which makes development of custom validators and PhaseListeners a pain. Is there a better way to have access to debugging & development facilities?

How to integrate custom PhaseListener in faces-config.xml?

I want to implement a custom PhaseListener in my faces-config.xml like it is suggested at stack overflow. So this is my faces-config.xml:

<lifecycle>
        <phase-listener>org.apache.myfaces.extensions.validator.core.startup.ExtValStartupListener</phase-listener>
        <phase-listener>org.apache.myfaces.extensions.validator.beanval.startup.JSF2AwareBeanValidationStartupListener</phase-listener>
        <phase-listener>org.apache.myfaces.extensions.validator.beanval.startup.BeanValidationStartupListener</phase-listener>
        <phase-listener>de.azt.MyPhaseListener</phase-listener>
</lifecycle>

And this is MyPhaseListener-Dummy:

public class MyPhaseListener implements PhaseListener {

    @Override
    public PhaseId getPhaseId() {
        return PhaseId.RENDER_RESPONSE;
    }

    @Override
    public void beforePhase(PhaseEvent event) {
        // Do your job here which should run right before the RENDER_RESPONSE.
    }

    @Override
    public void afterPhase(PhaseEvent event) {
        // Do your job here which should run right after the RENDER_RESPONSE.
    }

}

But this approach leads the application server to crash:

HTTP Status 500 - serialFactory

type Exception report

message serialFactory

description The server encountered an internal error that prevented it from fulfilling this request.

exception

javax.servlet.ServletException: serialFactory
    javax.faces.webapp.FacesServlet.service(FacesServlet.java:229)

    ch.ivyteam.ivy.dialog.execution.jsf.controller.IvyFacesInstanceFilter$1.call(IvyFacesInstanceFilter.java:55)
    ch.ivyteam.ivy.dialog.execution.jsf.controller.IvyFacesInstanceFilter$1.call(IvyFacesInstanceFilter.java:1)
    ch.ivyteam.ivy.security.internal.SecurityManager.executeAsSystem(SecurityManager.java:1425)

So how is it possible to implement a custom PhaseListener?
