Counter using Struts Taglibs

[Vinay <vi...@mdp.net>]

Hi All,
    How can I define counters using Struts EL tag libraries for printing purposes in JSP pages



Here is an example

<table border="1">
 <c:forEach var="transid" items="${trans.transactions}">
 <tr>
  <td><c:out value="${transid.acctno}"/></td>
  <td><c:out value="${transid.testcode}"/></td>

if($transid.testcode=="ts"  ) tscount=tscount+1;   

  <td><c:out value="${transid.srcfac}"/></td>
   <td><c:out value="${transid.dateofservice}"/></td>
   <td><c:out value="${transid.htkey}"/></td>

 </tr>
 </c:forEach>
 
</table>

In the above code i would like to print the total and number of iterations the for loop performed.

I would also like to do some condition to inside the for loop to print another specific counter

like 
eg:--
    if($transid.testcode=="ts"  ) tscount=tscount+1;   



I am novice and  have recently started using these tag libraries.Is there a link or web site which has tutorials on how to use the tag libraries.



Any help appreciated

thanks

It looks like you're really asking about JSTL tags, not Struts.

You can use <c:set> to increment a variable, as in

 <c:set var="counter" scope="session" value="${counter + 1}"> />

The JSTL specification is available at http://java.sun.com/products/jstl.
If that's too technical for you at the moment, there are also several
books on JSTL; more info on mine is available at the URL below.
