                 Key: WW-3284
                 URL: https://issues.apache.org/struts/browse/WW-3284
             Project: Struts 2
          Issue Type: New Feature
          Components: Core Actions
    Affects Versions: 2.1.8
            Reporter: Graham Leggett


The attached patch brings in support for a "Number" tag, to compliment the 
"Date" tag, exposing the java.text.NumberFormat class.

The main purpose of this tag is to render currency amounts, which are typically 
expressed as a java.util.Currency and a java.math.BigDecimal.

Currently, you can render currency amounts using a format string, but this 
presupposes that you preselect a given currency, with a given symbol, and given 
fraction digits.

With this tag, you are able to take a UBL XSD, put it through JAXB to produce a 
set of javabeans, and print currency amounts without being forced to pre-render 
the amounts in the action class.
