Formatting double/floats in bean:write and html:text

["Dowd, Brian" <bd...@lehman.COM>]

Hi,
    I'm a relative newbie to struts, so apologies if this is a simple
question, I did look
around and failed to find the answer.  Basically I want to know how to
display a
number in specific ways using the <bean:write ...> <html:text...> mechanisms
where
the number is a double, i.e. rather than the number "1.2459999999" appearing
I want
to arbitrarily be able to display it to s specific number of decimal places,
i.e. 3 above
giving me "1.246".  Also, is there any way to specify parenthesising
negative numbers
i.e. instead of -23 display (23)  (This is common format in banking).  Has
anyone done 
this ?  I would have expected there to be some kind of attributes on the
tags to allow
for the specification of NumberFormat details (i.e. such as locale,
grouping, places etc)
but I couldn't find any such one ...... I would rather not subclass the
bean:write and
html:text tags for this purpose .... any ideas ?

Thanks in advance.
Brian.

I already had a tag, so I don't use the struts version, but the one I 
implemented I added a parameter called formatter which is the name of a 
bean on the page that implements the Formatter interface in java.  Works 
really nice.  I'm sure it wouldn't be hard to extend the bean:write to 
take a formatter parameter and apply it to the output.
