You can do something similar in spirit to this with the existing
org.apache.shale.util.Messages class. The javadocs describe how to define
an application scope managed bean, configured for a particuar resource
bundle. Let's say you stored this under managed bean name "messages". Now,
you can generate formatted messages with it:
Messages messages = (Messages) getBean("messages");
Locale locale = context.getViewRoot().getLocale();
String localizedMessage = messages.getMessage("message.key",
locale, new Object[] { ... parameters ... });
Is that close enough to what you are after?
What do you think?
