Globalization Localization in Java (to be used in .Net)

Hello,

I am a .Net developer and trying to understand and implement the concept the subject. I need to localize the content of the web page and not just setting the culture.

In .Net, have 2 ways to localize a web page.

1) Creating resource files for individual language and load the relevant upon user selection.

2) Creating a global resource file, add text for individual language i.e. adding text for a particular resource and read the relevant information.

for both the cases, we must understand, read and write that language (of course, we can use the translation tool).

How do you implement the same in Java?

I remember, a friend of mine who is Java developer, explained some VRA, VRS, I mean something to display Japanese language for their Japanese roll-out.

Thank you.
