Struts : How to iterate until a value is reached

I am calculating the number of pages in a search screen in an Action class. I need to iterate from 1 to to display page numbers with links, and I can't find a way to do this with <s:iterator>

The java equivalent code will be, Please let me know where there is a way to achieve this in a JSP with struts 2.0 tags.

    for ( int i = 1; i <= pageCount; i++ ) {
        // print page no
    }

Thanks in advance.

http://struts.apache.org/2.x/docs/iterator.html

Use the "begin" and "end" attributes of the <s:iterator> tag for easy-to-read loops.

You can also play OGNL games, like:

<s:iterator status="stat" value="(5).{ #this }">

which will loop five times.

Values can come from an action property as normal.

For using a look in the JSP side of your S2 application you have the way to use Struts2 Iterator tag.

This iterator tag take a collection as input source of iteration. If you are using S2 version 2.1.7 or higher, you can take the advantage of begin, end and step attributes.All you need to have a collection in your Action class with its getter and setters and in your JP you have to do something like

<s:iterator value="days">
  <p>day is: <s:property/></p>
</s:iterator>

For details refer to the tag documentation

You are free to use S2 if tag inside the iterator tag to place various conditions as per your requirements
