Iterate certain number of times?

[dh...@lexmark.com]

Hi.

Am wanting to iterate a certain number of times, based on a value in my form
bean, to create a set of page links for the number of pages the user can view
(similar to at the bottom of most search engine results).

How do I do this with Struts?  Obviously I am not iterating over a collection.
But surely it is possible - what am I missing?

Many thanks,

Dave

Try the pager taglib from jsptags.com
http://jsptags.com/tags/

I know its not that elegant, but generate an array of page numbers in your
ActionForm based on the count

private int pageCount;

public String[] getPages() {

  String[] pages = new String[pageCount];

  for (int i = 0; i < pageCount; i++) {
    int j = i + 1;
    pages[i] = ""+j;
  }

  return pages;

}

Alternatively, write your own Tag which will look up a specified value in
your bean and loop the appropriate number of times.

Hi,

There's a good pager taglib at jsptags.com. I've used it in a struts app and
does the job quite well when embedded in the iterate tags.

<logic:iterate>
   <pg:item>
 	Item Details
   </pg:item>
</logic:iterate>

Hope it helps,
karl
