Subject SV: date format problems
Date Fri, 07 Mar 2003 14:26:49 GMT
Yes, it's a good point, but the only place my date is a String, is in
the ActionForm.

Would you store the date as long there?

Never try to store a date as a string. It creates a lot of date format
problems. As I have said, store it as a long so that you can easily do
the conversion.

Hi.
Thanks for all the answers

I was trying different things because nothing would work for me.

I need one thing:

Convert the String value theForm.GetMyDate() so that I can insert it in
my sql as yyyy-MM-dd.

I get the error java.lang.IllegalArgumentException: Cannot format given
Object as a Date

I will look at BeanUtils.copyProperties( beanToCopyTo, beanCopyingFrom
);, but it is probably to complicated for me just now!

What is the best way to fix it?

The "standard" for an actionForm is to have every field as String.
All conversion (which should really be thought of as business logic)
should
occur in the Action classes or further down the food chain. If this is
not
possible in your case or does not solve what your working on then can
you
please give more details?

I'm no expert at struts but I  convert and validate my dates in my
Action or
Business Class instead of the Form.  I could be completely off-base here
in
my interpretation of the struts ActionForm though........

Hi.

I have an action that gets a date from the MS SQL 2000 in yyyy-MM-dd. I
convert it with simpledateformat as dd-MM-yyyy and put it in a jsp form.
When submitting the form the date must be coverted back to yyyy-MM-DD
before another actions update the db.

I am trying to convert the date value in the ActionForm, but I am
getting the following error.

Any idears? I am lost and it is very urgent
