How do I use message bundles from my backing bean

[Jag Bains]

Hi

I have a backing been which extends AbstractPageBean.
I want to output a message from the bundle

e.g.
this.info("message fro m bundle");

How do I do this?

Thanks

Jag

Makes no sense to me. It is not part of Sun JSF API. What library are you talking about? Are you using some visual editor which autogenerates some code heap for you? If so, do you actually understand that code in terms that you´re perfectly able to write it all yourself? If not, I would recommend to stop using the visual editor for a while and write JSF code yourself until you´ve a good grasp on JSF.

Use ResourceBundle API to load the desired message bundle.
Use FacesContext#addMessage() to add a new FacesMessage to the context.

Sorry I should have mentioned that I am using Netbeans 6.5

My JSF page is (login.jsp):

</jsp:root>
 

I have a webuijsf:messageGroup id="messageGroup1" on the page and I want to populate it with a message from the page bean login.java as follows:

package vjsftest;

import com.sun.rave.web.ui.appbase.AbstractPageBean;
import com.sun.webui.jsf.component.PasswordField;
import com.sun.webui.jsf.component.TextField;
import org.apache.log4j.Logger;
import javax.ejb.EJB;
import javax.faces.FacesException;
import javax.persistence.Transient;
import com.sun.webui.jsf.component.Hyperlink;

public class Login extends AbstractPageBean {

    private void _init() throws Exception {
    }

    private TextField userCode = new TextField();

    public TextField getUserCode() {
        return userCode;
    }

    public void setUserCode(TextField tf) {
        this.userCode = tf;
    }
    private PasswordField password = new PasswordField();

    public PasswordField getPassword() {
        return password;
    }

    public void setPassword(PasswordField pf) {
        this.password = pf;
    }

    public Login() {
    }

    @Override
    public void init() {
        super.init();
        try {
            _init();
        } catch (Exception e) {
            log("Login Initialization Failure", e);
            throw e instanceof FacesException ? (FacesException) e: new FacesException(e);
        }
        
    }


    @Override
    public void preprocess() {
    }


    @Override
    public void prerender() {
    }


    @Override
    public void destroy() {
    }


    protected SessionBean1 getSessionBean1() {
        return (SessionBean1) getBean("SessionBean1");
    }


    protected ApplicationBean1 getApplicationBean1() {
        return (ApplicationBean1) getBean("ApplicationBean1");
    }


    protected RequestBean1 getRequestBean1() {
        return (RequestBean1) getBean("RequestBean1");
    }

    public String loginBtn_action() {
            this.info("Message from resource bundle");
            return null;
    }

    
}
 

In my loginBtn_action, I want to display a message that is displayed in messageGroup1.
What should I do to display a message from the resource bundle?

Netbeans is just an IDE.

As said, use ResourceBundle API to load the desired message bundle and use FacesContext#addMessage() to add a new FacesMessage to the context.
