I have problems implementing ImageIcon

[Jonathan Carter]

I have the following code working on my PC (Jbilder jdk1.3) ( but when I try
and run it on my linux server I get the attached error (jdk 1.2.2)

I am trying to get the height and width of an image from the server's disk.

Can anyone help ?

Jonathan

My code looks like this :
=========================
public void gwImageSize(String T_IMG) {
ImageIcon img;
img = new ImageIcon(T_IMG);
width = img.getIconWidth();
height = img.getIconHeight();
}

The error looks like this :
===========================

for interest, the JSP looks like this :

isThreadSafe="false" %>
<jsp:useBean id="GWF" class="gwdb.gwFormat" scope="session"/>

<%
GWF.gwImageSize("/usr1/www/filestore/scrap/t3.jsp");
%>
