DCEVM的主要网站没有明确说明如何在Linux上安装DCEVM.在Linux中运行“java -jar installer.jar”(通过PuTTy访问时)给了我以下异常.
[admin@LINUXBox jdk1.7.0_55]$java -jar DCEVM-full-7u79-installer.jar java.awt.HeadlessException: No X11 DISPLAY variable was set,but this program performed an operation which requires it. at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:207) at java.awt.Window.<init>(Window.java:535) at java.awt.Frame.<init>(Frame.java:420) at javax.swing.JFrame.<init>(JFrame.java:224) at com.github.dcevm.installer.MainWindow.<init>(MainWindow.java:43) at com.github.dcevm.installer.Main.main(Main.java:46) Exception in thread "main" java.awt.HeadlessException: No X11 DISPLAY variable was set,but this program performed an operation which requires it. at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:207) at java.awt.Window.<init>(Window.java:535) at java.awt.Frame.<init>(Frame.java:420) at java.awt.Frame.<init>(Frame.java:385) at javax.swing.SwingUtilities$SharedOwnerFrame.<init>(SwingUtilities.java:1757) at javax.swing.SwingUtilities.getSharedOwnerFrame(SwingUtilities.java:1832) at javax.swing.JOptionPane.getRootFrame(JOptionPane.java:1697) at javax.swing.JOptionPane.showOptionDialog(JOptionPane.java:863) at javax.swing.JOptionPane.showMessageDialog(JOptionPane.java:667) at javax.swing.JOptionPane.showMessageDialog(JOptionPane.java:638) at com.github.dcevm.installer.Main.main(Main.java:51)
如果需要,我也准备使用安装了Desktop Linux的Virtual Box来尝试,然后我可以将(修补的JDK)复制到我原来的Linux框中.
那么,如何在Linux上安装DCEVM(对于Java 7)?我需要一台基于桌面的Linux吗?
编辑:
这是Sharad的第一个答案建议的几个命令的输出:
[admin@TESTBEDPEGSEARCH jdk1.7.0_55]$echo $DISPLAY [admin@TESTBEDPEGSEARCH jdk1.7.0_55]$java -version java version "1.7.0_55" Java(TM) SE Runtime Environment (build 1.7.0_55-b13) Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03,mixed mode)
EDIT2:
我在Windows中使用DCEVM相当长的时间.
