For example:

if (firstname==lastname)
    { some action... }

To perform tests and loops you can use the Struts logic tags. What you are looking for are the <logic:equal> and <logic:iterate> tags. These work easily if you want to test or loop over properties of action form beans, thanks to their property attribute.

You could also use the <c:if> and <c:forEach> tags of JSTL for operations like these (these are generic tags that don’t depend on Struts).
