Thanks for the class. I have a few questions about it. What exactly is the
point of the array of parse patterns? It seems like you only use the first
one. It would be great if there was a way for me to specify a parse pattern
as the conversion is happening because in different situations I want a
different date format. The previous person was also correct. I want to
call the date format tag on the specific list object rather than on the
whole list. However so far I can only get my converter to be automatically
called if I try to display the address using the tag because it
calls toString. I ideally would like my converter to convert an
XMLGregorianCalendar object to a date object and then I can use the
tag on that date object. I can't seem to get my converter to be
automatically called in this situation. Any thoughts on this?
This is the code I would ideally use and have the converter automatically
convert my XMLGregorianCalendar object to a date object and use the struts
tag to format my date:
