Ooo, didn't know I could use an iterator like that, I have always
defined the var. Thanks for the tip, however do you not find that other
way easier for readability? Just thinking an outsider might be left
wondering where "price" came from.. Maybe I am missing the point.

I've never used the iterator tag like that, the standard way to use the
Struts 2 Iterator would be:

<s:iterator value="products">
  <span class="product-name"><s:property value="name
<http://product.name/>
"/></span>
  <span class="product-price">&pound;<s:text
name="format.currency"><s:param
value="price"/></s:text></span>
</s:iterator>

Since the iterator tag puts the current value on the top of the stack,
there's no reason to define a variable to hold it.  It's much simpler to
just use the value stack to pull the values from.  Don't know if this
might
help or not.
