我读过在Linux上运行Weka只需要两个步骤，即：

I've read that there are only two steps needed to run Weka on linux, that is:

将weka目录添加到CLASSPATH

运行 java -jar weka.jar

Add weka directory to CLASSPATH

Run java -jar weka.jar

运行上面的命令之后我得到：

After running above command I'm getting:

Exception in thread "main" java.lang.ExceptionInInitializerError Caused by: java.awt.HeadlessException at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:207) at java.awt.Window.<init>(Window.java:535) at java.awt.Frame.<init>(Frame.java:420) at javax.swing.JFrame.<init>(JFrame.java:218) at weka.gui.LogWindow.<init>(LogWindow.java:252) at weka.gui.GUIChooser.<clinit>(GUIChooser.java:215)
