tell me more icon Resource Bundle

By default, JDeveloper does not automatically create text resources in the page's resource bundle when you edit UI components in the visual editor. If you wish to use a resource bundle, select the Automatically Synchronize Bundle option in the Project Properties dialog, Resource Bundle page. The default bundle type is Properties Bundle, which is a PropertyResourceBundle properties file or a plain-text file containing translatable text. A properties file can contain values only for String objects. If you need to store other types of objects, use a ListResourceBundle instead.

Project Properties, Resource Bundle

When Automatically Synchronize Bundle is selected, after you enter text in the visual editor and press Enter, JDeveloper displays the text as an EL expression:

Visual editor, EL expression

JDeveloper also creates the properties file. For example:

                               
#
                                
SOME_TEXT=Some Text
