Where do I register such a convertor? Simply add this code to my Action or do

I've figured out what my problem was, but now sth else pops up. I have a field
with type java.util.ArrayList. When I enter the form, the precedent Action
fills the form. On screen, the ArrayList is correctly processed. Now, when I
submit the form, all those values are gone.
I added <html:hidden property="txtFieldForArrayList" /> to my JSP, but it turns
out that was the problem for the previous error. When I remove that field from my JSP,
everything works correctly for the first time, but the second time I enter the page, this
ArrayList is gone.
What am I doing wrong here?
Is the ArrayList gone or empty? Presumably just empty - since
DynaActionForm's should re-create the list even in request scope. You
could change the form to be session scope - or you need to add some
"lazy list" type behaviour

If you use one of the "lazy" ActionForm flavours it does this for you:

Because BeanUtils (at the moment) comes with a registered converter
for jav.sql.Date - but not for java.util.Date. If you want it to
handle String-->java.util.Date you need to register a Converter for
it:
Converter dateConverter = new MyDateConverter();
ConvertUtils.register(dateConverter, java.util.Date.class);
Your date converter will need to implement the following interface:

The section 4.3.1 you refer to below tells you which types are
supported "out of the box".

http://struts.apache.org/1.3.5/userGuide/building_controller.html, see section
4.3.1.

There's also no validation on that field.
