You need to provide the so called client id, which you'll find on UIComponent.

The following is a quick example of how to use this.

Consider the following bean:

@ManagedBean
@RequestScoped
public class ComponentMsgBean {

    private UIComponent component;

    public UIComponent getComponent() {
        return component;
    }

    public void setComponent(UIComponent component) {
        this.component = component;
    }

    public String doAction() {

        FacesContext context = FacesContext.getCurrentInstance();

        context.addMessage(component.getClientId(), new FacesMessage("Test msg"));

        return "";
    }

}

being used on the following Facelet:

This will add a Faces message with content "Test msg" for the outputText component used in the example.
