isn't there a bean:size tag, which is designed for this?

Subject: Re: Using the iterate tag
Personally, I would wrap the ArrayList in a bean and expose the size (or
row count) with an accessor. Then you can do things like this:
logic:notEqual name=result property=rowCount value=0
... iterate the list
/logic:notEqual
logic:equal name=result property=rowCount value=0
... explain that there is nothing to interate
/logic:equal
The interate tag is designed for this strategy. You can specify the bean
with the name property, and the accessor for the ArrayList with the
property property (sic).

Hi,
I am try to use the iterate tag to display a list of strings on a
page. The strings I am using have been initialized in an ArrayList.
I want to be able to check how many strings are in the list so that I
can display a certain amount on a number of pages. This is because I
do not know how many strings I will have in advance. The example
below is a simulation, but I seem to be getting an error when I try to
use a jsp runtime expression such as %= size %.
This is the example I am trying at the moment, please help if you can.
%
java.util.ArrayList testList = new java.util.ArrayList();
for( int i = 0; i 30; i++ )
testList.add( new Integer( i ) );
int size = testList.size();
%
logic:iterate id=playerStats collection=%= testList
% type=java.lang.Integer
offset=0 length=%= size %
%= playerStats %
/logic:iterate
and this is the error I am getting.

Greetings, I was wondering if anyone was implementing the DAO design
pattern
using JDO. I am currently re-engineering a web application and plan
to use
Struts for the web tier and am looking for a non-J2EE solution for
the
business/persistence layer. I have done some cursory research on JDO
and was
curious if anyone was using it. If so, which implementation, and how
you are
using value objects with it.
thanks,
robert
