RE: using javax.swing.ImageIcon with servlet

You should launch X otherwise you can't get a graphics context 
whether on or off screen. 
I think.

Subject: using javax.swing.ImageIcon with servlet


Hello,

  In my servlet I use the package javax.swing.ImageIcon to get the size
of an image. But apparently, this package need a X11 display. On my server
I don't have X launched. Do you see how to solve this ? Do I need to use
another package ?

  Here is my error:

Error: 500

Location: /bib
Internal Servlet Error:

java.lang.InternalError: Can't connect to X11 window server using
'<mon serveur>:10.0' as the value of the DISPLAY variable.
