Have your action class build a collection or array of Strings representing the days of the month and put that collection in request scope. Then, in your JSP, use the <htmlptions> tag to show that collection as a group of options. Here is a link to the Struts documentation that explains how to use this tag.

No

In the jsp I have to just populate the option values from 1 to 30

I can make use of for loop for that

without that are there any specific struts tags for that?

while you can use a for loop in a scriptlet to do this, it is not a good practice to do so. Best practice for building Struts web applications recommends putting as much logic as possible in the Action class, and putting only display logic in the JSP. That's why I would consider the method I presented in my previous post as "best practice".

However, if you want to create options with a loop, I'd suggest using the JSTL <c:forEach> tag. The <logic:iterate> tag only iterates over an existing collection, so it wouldn't work in this case.
 
I agree. Here's the link: http://aspose.com/file-tools
