Re: Handle images path in one place

[Erik Weber]

Sorry, I was using the html-el tag, not the html tag:
<html-el:img src="${somePath}/images/foo.jpg"/>
I think you should be able to do what you want without the el tags if 
you are using JSP 2.0, but to be honest, someone else needs to jump in 
and bail me out here on that. I think it's a configuration problem. (web 
app 2.3 v 2.4 or something?)

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

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
