Re: fmt:formatNumber to format currency does not display negative amounts

[Larry Young <ly...@dalmatian.com>]

Radhika,

         Sorry, I don't have direct experience with JSTL, so I can only 
give you suggestions where to look.

         The number (100) is an accounting equivalent for -100, both 
specify a negative value.  The one you get is generally dependent on your 
locale.  Based on the JSTL docs, and assuming that JSTL is simply utilizing 
the Java DecimalFormat class, it would look like you need to specify the 
"patttern" attribute for the "formatNumber" tag.  I'm not positive that it 
takes the same value as the Java class "applyPattern" method does, but if 
so, then you need to supply it with both a positive and negative pattern if 
you want to enforce the minus sign on negative values.

         I made my assumptions by looking at the JDK1.4 javadocs and also 
the JSTL docs.  Good luck.

Larry
