Ronald: For what it's worth, here's my ValueUtils.java which has a couple of conversion routines for dates, etc., in it. Bear in mind that I'm no more of a Java expert than I am a Struts expert.
Just to be complete, here is a snippet of code from one of my Action
classes that invokes a couple of the ValueUtils methods:
BeanUtils.populate(paymentForm,payment.describe());
paymentForm.setDateProcessed(ValueUtils.getLocalizedDateString(payment.g
etDateProcessed(),
locale));
paymentForm.setAmount(ValueUtils.getLocalizedCurrencyString(payment.getA
mount(),
locale));
I guess I should add that I have a custom .describe() method in my
"payment" bean, which I use instead of the standard
BeanUtils.describe(). This is recommended by a number of sources; you
code a custom .describe() method in your bean which returns a string
similar to that returned by BeanUtils.describe(), but only for fields
that do NOT require special handling. Then, you use the methods in your
ValueUtils to "manually" convert the remaining fields.
I assume that you're familiar with the fairly standard method of
combining BeanUtils.describe() and BeanUtils.populate() to transfer
fields from one bean to another, but if not, write back and I'll point
you to the source I cribbed it from. Check Ted Husted's webpage and the
Struts Tips on Jguru.
Hope this helps.

Thank you very much Charles!
I will try to do it with that. If anyone feels great today and feels
like adding some sample code it would make my day complete! ;-)
Regards,
Ronald
