When developing a web application localized in multiple languages,
it is sometimes necessary to view the JSPs in the different
languages to fix the localization and web design issues related
to internationalization.
Open a JSP.
Choose Text > Resource Locale...
The Resource Locale dialog is displayed, allowing you to select any of the locales in which the web application is localized.
Select a locale from the drop-down list, and click OK to confirm the dialog.
Notice that the page displays the localized text and images from the selected locale.
