JSF 2.0: use Enum values for selectOneMenu [duplicate]

Answer 1

I use this simple approach, it is quite optimistic, you can customize it for your own purpose. I put the following code in a reusable bean, that can be called from your application at any time, so you can use any of your enums declared in your package.

public List fromEnum(String cname) {
        List names = new ArrayList<>();
        try {
            Class c = Class.forName(cname);
            Object[] r = c.getEnumConstants();
            if (r != null) {
                for (Object o : r) {
                    names.add(o.toString());
                }
            }
        } catch (ClassNotFoundException ex) {
            FaceUtil.ShowError(ex);
        }
        return names;
    }
public static void ShowError(Exception ex) {
        FacesMessage msg=new FacesMessage(FacesMessage.SEVERITY_ERROR,ex.getMessage(),"Error Message");
        FacesContext.getCurrentInstance().addMessage(null, msg);
        }

Now use it in the xhtml file as follows:
