Thanks for the reply, Laurie! This suggestion of yours works perfectly!
(Although, I had to change var="url" to id="url")
<s:url id="url" value="%{item.imageURL}"/>
${url} </img>
Your other suggestion doesn't work. I'd like to know why this doesn't work,
as this was what I first tried (I mentioned this in my original post, btw)
${item.imageURL} </img>
Results in this exception (Glassfish v2 RC, Struts 2.0.9, JDK 1.6.02,

Could you explain why the EL triggers this exception? Is that a bug or am I
doing something wrong?
Also, what is the ${myObj.property} and %{myObj.property} EL syntax called?
Where can I read documentation on it?
