If pathParam is a bean you pass in through the request or any scope you could use
<bean:write> to output the value of the bean without resorting to scriplets.

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.

I am experiencing difficulty using tag libraries and the passing through of scripting variables in attributes. Specifically I'm trying to add an onclick value to an <html:img> tag but this is generic for any tag in the Struts libraries where the user can supply a value to an attribute.
When the following markup is used in a jsp: <img src="minor.gif" alt="" onclick="confirmAction(<%= pathParam %>);" /> <img src="minor.gif" alt="" onclick=<%= "\"confirmAction(" + pathParam + ");\"" %> /> The resulting HTML is: <img src="minor.gif" alt="" onclick="confirmAction(Foo);" /> <img src="minor.gif" alt="" onclick="confirmAction(Foo);" />
As you can see either one of the jsp versions 'work' to create a good onclick method.
But when the code is changed to use the <html:img> tag it doesn't work. That is with the following jsp markup: <html:img src="normal.gif" alt="" onclick="confirmAction(<%= pathParam %>);" /> <html:img src="normal.gif" alt="" onclick=<%= "\"confirmAction(" + pathParam + ");\"" %> /> The resulting HTML is: <img src="normal.gif" alt="" onclick="confirmAction(<%= pathParam %>);"> <html:img src="normal.gif" alt="" onclick="confirmAction(Foo);" />
While the first instance of <html:img> gets changed into the <img> markup the scripting variable pathParam does not get resolved. In the second case the scripting variable gets resolved but the <html:img> does not get changed into its appropriate <img>.
Why? And how do you get the correct behavior?
Any help is greatly appreciated. Lori Cook
