I don't know of any quick-and-easy way to do this (unless you are
using JSF, where you declare the supported locales explicitly in a
faces-config.xml file). But here's a brute force strategy that should
work, if you are on a Servlet 2.3 or later container.
* Call ServletContext.getResourcePaths("/WEB-INF/classes"), which
returns you a set of context relative paths to all the files under your
/WEB-INF/classes subdirectory.
* Scan down this list and match the ones that are related to your
resource bundle (i.e. things that match "*/text*.properties") to
build your list of available locales.
* If you have properties files in JARs under /WEB-INF lib, you can
use ServletContext.getResourcePaths() again to get paths to all
the JAR files. Then, you can use the utility classes in java.util.jar
to scan the table of contents of each JAR file and (again) match
the names to an appropriate pattern.
