How about JSTL?

<c:forEach items="mybean" var="index" varStatus="stat">
<c:select>
<c:when test="${stat.count %2 == 0}">
stuff for even row
<c:\when>
<ctherwise>
stuff for odd row
<c:\otherwise>
</c:select>
</c:forEach>

But I need to iterate over a Hashmap..
In which I am having a bean,contains properties like..name and
hashmap.

So i have to use <foreach> inside a <foreach>...

and also inside the condition i need to make use of the bean
properties.

One more think..

can't we use expression language inside struts tag?..

like below

<bean:define id="mybean" value="${(k%2)==0}"/>

currently i am trying to use like this but its not working...

do u know any other way of implementing this..


Once again thank u..

You can nest forEach loops

Yes. If your servlet container supports servlets 2.4, then this is no
problem at all. Servlets 2.4 allows you to put EL anyplace in your JSP
page. If you're using an earlier container (like WebLogic 2.8, which
we're just now transitioning off of), you can use the Struts EL
libraries, which come with the Struts package.

I did it by using a property in the bean, for example:
<div class='<bean:write name="rotateColor" property="colorClass" />'>

rotateColor is loaded as a class and passed in through request and is
defined as such:

private String colorClass = "even";

public String getColorClass() {
colorClass = colorClass.equals("odd") ? "even" : "odd";
return colorClass;
}

public void setColorClass(String colorClass) {
this.colorClass = colorClass;
}

I am using servlet 2.4...only still it is not working..then
I did google n found that we can't use a customtags as customtag
attributes..
