[OmniFaces utilities 2.1] Get all application resource bundles registered as <resource-bundle> in faces-config.xml

[OmniFaces utilities] The getResourceBundles() method returns all application resource bundles registered as <resource-bundle> in faces-config.xml. If there are no resource bundles registered, then this method just returns an empty map.


Let's suppose that we have a resource bundle with "short" messages and a resource bundle with "full" messages:

Is quite simple, just check the content of the msgs.ShortMessages:

English and French ( and

English and French ( and

Now, in faces-config.xml, we declare both resource bundles, as below (for the "short" messages we have attached the var named, short, and for the "full" messages, the var named, full):


Now, you can use both resource bundles in the application views by indicating the proper var. For example, a dummy usage is below:

<h:outputText value="#{short['NAME']}"/>
<h:outputText value="#{short['SURNAME']}"/>
<h:outputText value="#{full['NAME']}"/>
<h:outputText value="#{full['SURNAME']}"/>

Now, programmatically speaking, we can access these resource bundles via Faces#getResourceBundles(), as below:

Map<String, ResourceBundle> resourcebundles = Faces.getResourceBundles();
for (Map.Entry<String, ResourceBundle> entry : resourcebundles.entrySet()) {
     // entry.getKey() - this is the var name (short, full)
     // entry.getValue().getString("NAME")); - for short var
     // entry.getValue().getString("SURNAME")); - for full var
