How can I get a message bundle string from inside a managed bean?
You can get the full qualified bundle name of <message-bundle>
by Application#getMessageBundle()
. You can get the current locale by UIViewRoot#getLocale()
. You can get a ResourceBundle
out of a full qualified bundle
name and the locale by ResourceBundle#getBundle()
.
So, summarized:
FacesContext facesContext = FacesContext.getCurrentInstance();
String messageBundleName = facesContext.getApplication().getMessageBundle();
Locale locale = facesContext.getViewRoot().getLocale();
ResourceBundle bundle = ResourceBundle.getBundle(messageBundleName, locale);
// ...
Update: as per the mistake in the question, you actually want to get the bundle which is identified by the <base-name>
of <resource-bundle>
. This is unfortunately not directly available by a standard JSF API. You've either to hardcode the same base name in the code and substitute the messageBundleName
in the above example with it, or to inject it as a managed property on <var>
in a request scoped bean:
@ManagedProperty("#{msg}")
private ResourceBundle bundle; // +setter
FacesContext context = FacesContext.getCurrentInstance();
ResourceBundle bundle = context.getApplication().getResourceBundle(context, "msg");
String message = bundle.getString("key");
here is key is property name which you want to access from properties file .
message = This is "message"
This entry is from messages.properites file. and "message" is "key" .
