- Persistent lang setting with routerconsole.lang=xx
- Loading any page with ?lang=xx changes the persistent setting
- Add a custom Jetty handler to load foo_xx.jsp if it
exists for language xx. This is for jsp files with lots
of text in them. Otherwise use inline translate methods.
Not for included jsps.
- Add a script to create and update messages_xx.po translation
files, and create ResourceBundles from them
- Add class to translate strings from cached ResourceBundles
- Add translate wrappers to HelperBase, FormHandler, and *Renderer,
so calls can be made from both jsp and java files
- Add two example translations on configupdate.jsp - one in
the jsp itself and one in the helper.
- This is for strings in routerconsole only. Will be expanded
to other webapps and the router later.
