way to print in alp order??

Hi,

How can I sort items, items='${company.sites}' in alphabetical order and print them?
Do I need to sort it in Java class first?

<c:forEach items='${company.sites}' var="site">
  <tr><td><ul><li class="${site.name}">
               <a href="${site.url}" target="_blank" class="${site.tag}">${site.name}</a>
            </li>
         </ul></td>                          
    <td style="width:25%">${site.lastUpdate } </td></tr>
</c:forEach>

i guess you need to sort the collection in servlet, before you get to jsp

If you can show me an example code, it will be very helpful.
If you could show me one that is not too hard!

I have a basic java question, ${company.sites}
I can see the Site class but I can't find the Sites class.
I can't find where Sites collection is.
How does this servlet syntax work?
I have this Java project and trying to understand what it is doing and fix bugs if I can..

you can simply include this scriptlet in your code

<%
List list = (List)session.getAttribute("company.sites");
Comparator comp = .... //comparator class defined to sort the sites
Collections.sort(list, comp);
%>

OK.
I came to understand that Com
Company class {
Company company;
...

public List<String> getOwnerNames() {
List<String> owners = LuceneConfig.getOwnernames();
return Collections.sort( owners );

}

public List<Site> getSites() {
List<Site> xsites = LuceneConfig.getSites();
return Collections.sort(xsites); <=== I need help this part...
}

There is no Collections.sort() so are you saying I need to use Comparable <Site> =...?

Also, tell us how you want to sort the List of sites. On the name = site.getName() ?
