Class MessageUtil

java.lang.Object

org.apache.aries.util.nls.MessageUtil

public final class MessageUtil
extends Object

This is a helper class for loading messages for logging and exception messages. It supports translating the message into the default Locale. It works out the calling Bundle and uses it to load any resources. If the resource bundle is of type java.properties then it tries to find the bundle first via the bundle getResources method, then via the getEntry method. If it is of type java.class then it'll use the bundle to load the class.
