Lori,
notice I took this to the struts list. The struts tags don't support
runtime expressions. There is a subset of struts tags that supports
EL (expression language). You might try the following approach:
<c_rt:set var="pathParam" value="<%= pathParm %>"/>
<html-el:img ... onclick="${pathParam}"/>
However, it'd be even better if you didn't need the first line. There
are times when scriplet expressions must be used (static variables),
but you should try to avoid them when you can.
