Erik:
This did not seem to work for me. The varuable is not being
substituted. I am using TOmcat 5.0.25 so it should implement
JSP 2.0.
Here is what I have in my JSP:
<% String buttonImageUrl =
PathUtil.getImagePath(request,"layout/homeButtonOver.gif");
pageContext.setAttribute("buttonImageUrl",buttonImageUrl);
String overImageUrl =
PathUtil.getImagePath(request,"layout/homeButtonOver.gif");
pageContext.setAttribute("overImageUrl",overImageUrl);
%>
<td><html:link action="/home.do" target="_top"
onmouseover="setImage('homeButton','${pageContext.overImageUrl}')"
onmouseout="setImage('homeButton','${buttonImageUrl}')" ><html:img
imageName="homeButton" src="${buttonImageUrl}" border="0"
width="140" height="52" /></html:link></td>
When I look at the source of the generate page, I get this:
<td><a href="/pricetracker/home.do" target="_top"
onmouseover="setImage('homeButton','${pageContext.overImageUrl}')"
onmouseout="setImage('homeButton','${buttonImageUrl}')"><img
src="${buttonImageUrl}" name="homeButton" height="52" width="140"
border="0"></a></td>
It is taking the variables as literals.
Any ideas?
Thanks,
Neil

Subject: Re: Handle images path in one place
Using the expression language, you can build paths like this:
<html:img src="${somePath}/images/foo.jpg"/>
The "somePath" variable could be an application scope attribute
(ServletContext attribute). I have done this before by writing a
(Struts) plugin that gets "somePath" from web.xml (init-param) and
stores it as a ServletContext attribute. Then it's availabe (as
shown above) in all tags in all your JSPs.
Not sure if there is a better way but that works. You can change
your image URL prefix simply by editing web.xml.

Hello,
I'm writting a web application using J2EE where several
pages can contains the same images.
I would like to have the path to these images into one place
an if possible into the same place for all images.
For instance in a file and have a tag to access like this
<html:img alias="dog">
like this I can move my images from one folder to another, I
will have only one file to update....
Does somebody use something similar?
TIA
