The typical approach would be to do the database query first, and store
the result in a collection. This way you can get any error handling out
of the way, before you start rendering the view, and you also know how
many records you will have going in. (And avoid rendering a inexcusably
long page to your users.-)
Using that approach, the Struts custom tag library has an Iterate tag
that you could use. In this example, meetings is now a collection (in
any scope) of meeting beans, with code and description properties. It
also uses another handy Struts tag, Bean.
<logic:iterate id="mtg" name="meetings">
<tr>
<td>Meeting Code <td> <bean:write name="mtg"
property="code">
<td>Meeting Description <td> bean:write name="mtg"
property="description">
</tr>
</logic:iterate>
Struts is actually a framework, but the custom tags have uses in almost
any Model 2 application. < http://jakarta.apache.org/struts >
Just a suggestion. Your mileage may vary.

hello fellas
have run into a small prob. I have made a custom tag that accesses a
database and prints the same. What i need is that, as the theory says,
to be
able to seperate the processing logic with presentation logic. My tag
looks
as follows :
<html>
<mtp:meetings >
<tr>
<td>Meeting Code <td> /* i want title to appear here> */
<td>Meeting Description <td> /* Description */
</tr>
</mtp:meetings>
</html>
Now, i am to get to repeat the <tr><td> to repeat for as many records
as i
have. However, where i am stuck is to get the data to appear in the
place of
comments -- any suggestions ?!!
