[jboss-l10n] Translations

[Thomas Heute]

For JBoss Enterprise Portal Platform (which has a large part of User 
Interface) we sometimes require some translation for few sentences in 
various languages, for instance if we add a validation on a form we need 
to know how to say  "The title length can't be longer than 10 
characters" in French, German, Simplified Chinese, Traditional Chinese, 
Italian...

What's the best process to get such sentences translated ?
