Hello, The Linux install kit is an Install4j application. As you can see from the stack trace the installer does not find the core Java class library (java.swing.*) of the Java virtual machine. I think your JVM installation is corrupt. Can you run a graphical Java application with that JVM ? Also please run the installer with a JVM from Sun Microsystems. The GNU libgcj Java virtual machine (which includes the libgcj.so library) cannot run <oXygen/> because it does not provide a standard encryption algorithm used to verify the license key. This was discussed also on the <oXygen/> forum where the supported and unsupported JVMs were discussed recently: http://www.oxygenxml.com/forum/ftopic1887.html Regards, Sorin Thomas Zastrow wrote:

Hi there,

I can't install Oxygen 7.2 on Kubuntu Dapper Dake. There is a Java-installation and the variables JAVA_HOME and JAVA are pointing to it. After starting oxygen.sh I get the error:

zastrow@schleppi:~/downloads/progs$ ./oxygen.sh Starting Installer ... java.lang.NoClassDefFoundError: javax.swing.JOptionPane at java.lang.Class.initializeClass(libgcj.so.7) at com.install4j.runtime.installer.Installer.reportExeption(Unknown Source) at com.install4j.runtime.installer.Installer.main(Unknown Source) at java.lang.reflect.Method.invoke(libgcj.so.7) at com.exe4j.runtime.LauncherEngine.launch(Unknown Source) at com.install4j.runtime.Launcher.main(Unknown Source)

Best,
