How to use resource bundle files in Java code?

Question

I've got my localized messages in a resource bundle file that the JSTL <fmt> taglib can use. Now I also want to use these messages from inside my Java code. How can it be done?

What I need is something like getMessage() for a key and getParameterizedMessage() for a key with parameters.

Update The following seems to work:

ResourceBundle messages = ResourceBundle.getBundle("messages");
String str = messages.getString("PF1");
System.out.println(str);

Object[] messageArguments = {
    "test"
};

MessageFormat formatter = new MessageFormat("");
formatter.applyPattern(messages.getString("IT4"));
String output = formatter.format(messageArguments);
System.out.println(output);

Load your message in java.util.Properties and have a helper class which if given a key will return you the value from the Properties.
