I made simple java gtk-software and got it compiled. When I try to run it, it
fails. Tryed on Fedora Core 4, and it worked on it.

Compiled with: javac -classpath
/usr/share/java/gtk2.8.jar:/usr/share/java/glade2.12.jar Main.java

Runned with: java --classpath
/usr/share/java/gtk2.8.jar:/usr/share/java/glade2.12.jar:. Main
java --classpath
/usr/share/java/gtk2.8-2.8.3.0.20060301.rh1.jar:/usr/share/java/glade2.12-2.12.2.0.20060301.rh1.jar:.
org.manet.Main

Error message when runned:
