RE: Handle images path in one place

[Neil Aggarwal]

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
