There's a Utility class in jsftemplating that does this:
com.sun.jsftemplating.util.MessageUtil
See the methods:
getInstance()
String getMessage(String baseName, String key)
String getMessage(String baseName, String key, Object args[])
String getMessage(Locale locale, String baseName, String key, Object
args[])
It includes message formatting, and caching of ResourceBundles in the
same way that $resource{} does. Do these methods meet your needs? If
not what's missing? NOTE: There's also a LogUtil.java class in the same
package that includes Logging api's (which also uses these message api's
when localizing log messages).
