list navigation in struts

[tj...@autozone.com]

Hello..

I am in need of a struts Best Practice...   Here is a brief description of
the scenario:

1.  Display a list of items on a page in table format.  Default to show the
first 50 items.  This master list of items has 1000+ entries.  These
'items' are basically just columns from a relational table.
2.  Provide  '>>', '>', '<', '<<' buttons to allow navigation through the
list. Also provide a html text box to allow changing of the default 50
items in the list.
It would look something like this in HTML:
<input type="button" name="beginning" value="&lt;&lt;" />
<input type="button" name="prev" value="&lt;" />
<input type="text" name="numitems" size="3" maxlength="3" value="50" />
<input type="button" name="next" value="&gt;" />
<input type="button" name="end" value="&gt;&gt;" />
3.  This functionality will be used on many pages/actions throughout my web
application.

Questions...
Is it best to handle this logic in the Action classes?  How?
Should I add the functionality to a Base Action class?
Is DispatchAction useful here?
Is there a good example of this scenario available anywhere?
Is there a Best practice recommened for this scenario?


Thanks in advance for your help!

TJ,
Take a look at the displaytag library 
(http://www.displaytag.org/index.jsp)

or
the Pager Tag library at
http://jsptags.com/tags/navigation/pager/index.jsp

If you search the archives, you will also find lots of
discussions about this topic too.

Regards,

Richard
