Hi, Glenn et al.
Following up on the format suggestion, I'd written a generalized format
tag that also handles dates. (Not as nice for dates as the datetime tag,
though =) Maybe the way I did formatting is of some help.
I modeled the "format" attribute after the java.text.Format classes.
Copying directly from my Javadoc:
A format is defined in much the same way as a Java MessageFormat. The
definition string has the form "format_type,style". E.g.,
"decimal,#,###.###" or
"date,short".
The format_type is any of "integer", "decimal", "date", "datetime", "time",
"message" and "choice".
The style options for integers and decimals are "default", "currency",
"percent" and [pattern], where the pattern is any allowed by
java.text.NumberFormat.
The style options for dates are "default", "short", "medium", "long",
"full" and [pattern], where the pattern is any allowed by
java.text.DateFormat.
More examples:
"decimal,currency"
"time,medium"
"integer,#,###"
"datetime,MM-DD-YYYY"
If my docs or source are of any use, just let me know. I've got a fully
implemented FormatTag and ParseTag as described here (not specific to
datetime). Maybe some of the ideas or code can be merged in to this or
another taglib.
Cheers,
Jonathan

Thanks Lee for the good bug report.
I have implemented a fix for the format tag that allows
it to ignore any whitespace in the body of the tag.
After I review the other datetime taglib feature requests,
I'll update the taglib on the jakarta site.
Thanks,
Glenn
