It would be great to have more Locales supported out of the box. They look more natural to me this way; your mileage may vary.
Again, a single line of code will do all we need: The simplicity and unusual syntax of the latter code come courtesy of the jQuery Ajax library, which is thoughtfully used by JMesa: If you would like the JMesa jar file in the Maven repositories I have decided to leave it up to the community to finish the work started. And we didn’t have to do a thing!
