Rob,
I find it useful (and easier) to work off of other's examples. Here's what I have done
in the past (actually last Friday):
<logic:iterate id="myList" name="countrystatcollection">
<tr>
<td class=text7><bean:write name="myList" property="countryname"/></td>
<td class=text7><bean:write name="myList" property="countryprocessedcount"/></td>
<td class=text7><bean:write name="myList" property="countrytotalcount"/></td>
</tr>
</logic:iterate>
Where:
1) myList: is just an ID that I made up
2) countrystatcollection: is a collection ( java.util.List ) that I set on the request
object in an action, which forwards to the page that contains the iterate tag.
//get an object array from helper class
CountryStat[] countryStatArray = ch.retrieveCountryCounts();
int iLength = countryStatArray.length;
for(int n = 0; n < iLength; n++ ){
//don't add nulls
if (countryStatArray[n] != null)
list.add(countryStatArray[n]);
}
request.setAttribute("countrystatcollection", list);
3) countrystat: is a simple bean that contains the following members:
protected String countryname = null;
public String getCountryname() {
return countryname;
}
public void setCountryname(String countryname) {
this.countryname = countryname;
}
protected String countryprocessedcount = null;
public String getCountryprocessedcount() {
return countryprocessedcount;
}
public void setCountryprocessedcount(String asCountryprocessedcount) {
this.countryprocessedcount = asCountryprocessedcount;
}
protected String countrytotalcount = null;
public String getCountrytotalcount() {
return countrytotalcount;
}
public void setCountrytotalcount(String asCountrytotalcount) {
this.countrytotalcount = asCountrytotalcount;
}
Hope this provides some insight into your problem.
