Allow me to answer my own question, before somebody tells me how stupid I am. 
I think the problem was my action wasn't set up correctly.  The following
snippets of jsp and java give me an array (xxx) containing the values that
were checked on the page.  In production, these fieldValues attributes would
obviously have user ids in them, rather than the hard-coded numbers like in
this example.

&lt;s:form action="tobin"&gt;
    &lt;s:checkbox name="xxx" label="1"  fieldValue="1"/&gt;
    &lt;s:checkbox name="xxx" label="2"  fieldValue="2"/&gt;
    &lt;s:checkbox name="xxx" label="3" fieldValue="3"/&gt;
    &lt;s:checkbox name="xxx" label="4" fieldValue="4"/&gt;
    &lt;s:checkbox name="xxx" label="5" fieldValue="5"/&gt;
    &lt;s:submit/&gt;
&lt;/s:form&gt;

-----------------------------

private int[] xxx;

@Override
public String execute() throws Exception {
    return SUCCESS;
}

public int[] getXxx() {
    return xxx;
}

public void setXxx(int[] xxx) {
    this.xxx = xxx;
}

If I may tag on a question here....

In your action then, how do you capture all 7 (for example) user id's that
the admin wants to delete?  I have a very similar design, I have a list of
users, and each user has a checkbox.  The admin can select multiple users to
either activate or deactivate.

In my action then, ideally, all I want back from the page is an array (or
some sort of collection) of each of the user id's.  I haven't been able to
get any form of this working yet.  Any tips?

(this is using Struts 2)

Try using the fieldValue attribute of <s:checkbox.../>

For example, if I use:

<s:checkbox name="user.id" 
            fieldValue="%{user.id}"/>

it renders as:

<input type="checkbox" 
       name="user.id" 
       value="42" 
       checked="checked" 
       id="confirmTest_user_id"/>
<input type="hidden" 
       name="__checkbox_user.id" 
       value="42"/>

I am using struts2, and I've been thinking for this questing for days.
[s:checkbox] seems won't work. Because it only renders boolean value.

Can anyone help?

are you using struts 1 ? if so, have a look at html:multibox.
basically you will need a collection in your action form (something like
List<String> selectedIds = new ArrayList<String>()).

for struts 2, i havent had time to check it yet.. just migrated to Struts 2
a couple days ago :P
