Registration.java.

package devguide.personalizedwelcome;

import org.apache.tapestry.IRequestCycle;
import org.apache.tapestry.html.BasePage;

public abstract class Registration extends BasePage
{
    public abstract void setUser(User user);
    public abstract User getUser();
    
    public void register(IRequestCycle cycle)  
    {
        Registration welcome = (Registration) cycle.getPage("Welcome");  
        
        welcome.setUser(getUser());  
        
        cycle.activate(welcome);  
    }
}

The listener method.

	Important
	The signature of the listener methods have to match the pattern, `public void listenerMethod(IRequestCycle cycle)`, or Tapestry will not recognize the method as a listener method.

cycle.getPage() retrieves the requested page object, Welcome, from the page pool.

	Note
	There is no URL or path involved in referencing pages, you simply reference them by their logical name as specified in the `<application>` specification.

Page objects are always of the type of their page class.

Copy the User in the Home page to the Welcome page before detaching the Home page from the request.

Activate the Welcome page. This will detach the Home page from the current request and attach to Welcome page instead.

User.java.

package devguide.personalizedwelcome;

public class User
{
    private String _title;
    private String _firstName;
    private String _lastName;
    
    public String getFirstName()
    {
        return _firstName;
    }

    public String getLastName()
    {
        return _lastName;
    }

    public void setFirstName(String string)
    {
        _firstName = string;
    }

    public void setLastName(String string)
    {
        _lastName = string;
    }

    public String getTitle()
    {
        return _title;
    }

    public void setTitle(String string)
    {
        _title = string;
    }
}

User is a plain Javabeans class that is a model value object.
