Setting and Getting Variables

[Dave Westerman <dl...@us.ibm.com>]

I am having a lot of trouble getting my head around how to access the 
different variables in Struts and JSP, and it's causing me all kinds of 
problems.

All I am trying to do is set a variable in my page from a variable in my 
Action class, in order to use it at various places in my page.

<s:set var="backgroundImage" 
value="'background-image:url(\"%{customImageFileUrl}\");'" />

The result is:
customImageFileUrl = /social/aggregator/sitetemp/site1/i_bg-hdr-sma.jpg
backgroundImage = background-image:url("%{customImageFileUrl}"); 

I've tried '#' instead of '%', and it also takes that as a literal. I've 
tried '$' instead of '%', and also using <s:property>, but both of those 
give me JSP compile errors.

Is there some way to put the value of 'customImageFileUrl' from my action 
class into a variable that I can use in the page?

Thanks!

What about using
<s:set var="backgroundImage"
value="'background-image:url(' + customImageFileUrl + ');'" />

<s:property value="backgroundImage"/>
