Hi, Could you tell me where I can add my GO.gif icon for the "GO" button I set up in StyleSheet.java? I checked the different files and can't seem to find an example. It's weird that I was able to compile just fine and did not get a javax.swing.ImageIcon NullPointerException without that .gif file included (as you mentioned). I made sure that visad.jar was at the very end of my classpath so that probably isn't the problem. Also, when you say to not run it by typing "java -jar visad.jar", how exactly should I run it? I was just opening up a new VisAD spreadsheet all over again. Thanks for your help, Michelle Michelle Kam (408) 742-2881 Lockheed Martin Space Systems Co.

The only thing I can think of is that perhaps when you execute "java visad.ss.SpreadSheet", it could be running a different version of the application. This could occur (I think) if you have a CLASSPATH that includes visad.jar before other folders that contain your modified version of the SpreadSheet. Or perhaps you are running "java -jar visad.jar" to execute the SpreadSheet, in which case it would use the SpreadSheet.class file within visad.jar instead of your recompiled version. -Curtis At 07:07 PM 6/6/2003, you wrote: >Hello, > >I sent an email asking about how to link a particular file with a button >added to the toolbar on the top of the spreadsheet.
