Best way to make Multiple languages site (JSP?)

High all,

I'm looking for the best way tot make a site in three languages.
Sure copy every html and make a second version of it in an other language but i recon nowadays there's a better way.
Since i will be making the site using JSP / JSTL maybe somehting in that direction.

Thx evb

What you could do is create a new table with all the different languages. You'd need a variable column, then an additional column for each language. The vBulletin forums do something like this, so in the actual scripts, there is no text, just variables such as $phrase[welcomemsg]. When the page is loaded, the page is edited so that these variables are replaced with the actual text for the correct language from the database.
