  hello
  

  
  i have a servlet which manipulate gif images
  it works on my local machine (WinXP)
  but when i try to run it on a linux server (with apache)
  it fails.
  

  
  knowing that in the first execution i have the following error
  

  
  "Cant connect to X11 window server using :0.0` as the value of the DISPLAY variable."
  

  
  And after i always still have the following error:
  

  
  "java.lang.NoClassDefFoundError: sun/awt/motif/MToolkit
         at org.apache.jserv.JServConnection.processRequest(JServConnection.java:
  320)
         at org.apache.jserv.JServConnection.run(JServConnection.java:188)
         at java.lang.Thread.run(Thread.java:475)"
  

  
  i think that this problem occurs in my servlet when executing this instruction:
  

  
  Image awtImage = Toolkit.getDefaultToolkit().getImage (...)
  

  
  the Xserver is already activated on my linux server
  the enviroment variable DISPLAY has the value:
  

  
  DISPLAY=:0
  

  
  do you have any idea?
  thanks
