Image Tag Library + scriplets

Question

I installed the jakarta imaging taglib to do some auto resizing of images. It works well aside from the fact that i cannot get my scriptlet to work in the img source.
<img:image src="/images/<% x_productImage %>"
        dir="generated
        name="<% x_productImage%>-new"
<img:resize width="900"/>
</img:image>It doesn't throw an error. And the when i view source it ignores the entire chunk of code and displays nothing at all.
Does anyone have any idea how i can get scriptlets to work?
Here is a link to the taglib if anyone is interested
http://jakarta.apache.org/taglibs/sandbox/doc/image-doc/intro.html
and here is the doc on it

Well attributes to a custom tag, you need to use scriptlet expressions <%= expr %>, not just plain scriptlet tags <% javaStatement; %>.
Also, when you want an attribute to be dynamic, make the whole attribute dynamic, rather than half and half, like you have with the src attribute on this tag. It saves problems in the end.
Something like this I think:
<img:image src="<%= "/images/" + x_productImage %>"
        dir="generated"
        name="<%=  x_productImage + "-new" %>">
  <img:resize width="900"/>
</img:image>Cheers,
