You can refer to the DisplayTag documentation about what collections
they
support, there are quite a few. I usually use a java.util.List of
JavaBean's And yes, you'll have to use JDBC, JPA, Ibatis,
Hibernate... to
get that data from the database into a structure that can be displayed.
As for your other question, take a look at the last column in my
example,
that's exactly what it does.

and the map holds attribute-value pair. No success, i think that is
a bad
solution.
and another question: i need the user id be passed to another action
as a
parameter. I've tried with a s:form and a hidden field, something like
<input type="hidden" value="<s:property>"> is the idea. It's about
an online
shop, and i'm having problems with:
1.- listing products from mysql
2.- adding products to the cart (from a mysql products list
i'm a little newbie with struts.....

wow, i think i got. I'll take a look.
thank you very much
my point is that i have a property which is a String, and i need that
string in two ways: as a literal string and as a parameter to another
action. Using "s:property", something like this:
<table>
<s:iterator value="#session.carrito">
<tr>
<td><s:property />
</td>
<td><s:url id="idResta" value="/Del.action">
<s:param name="politico" value="[0]"></s:param>
</s:url>
<sx:a accesskey="6" href="%{idResta}"
targets="secondaryContent" >Fuera</sx:a>
</td>
</tr>
</s:iterator>
</table>
sessio.carrito is a String ArrayList and iterator works. Each of that
string must be passed to another action, say Action2, like a form with a
hidden field. During Action2 (which delete "politico" from
session.carrito) there's a *java.lang.ArrayIndexOutOfBoundsException: -1*
I thought that "[0]" helds the actual value, same as "<s:property />".
Into "param" tag i've tried also with value="{ #this }" but i got that
java exception.
Something like:
<s:param name="politico" value="<s:property />"></s:param>
is my literal desire :)
My struts action has private String politico and getters y setters. I'm
not really sure if "politco" is viewed by Action2.
