应该是Security Level的问题。
准备打开java控制面板进行设置，发现安装的并没有控制面板程序
- 如果在你的bin目录下没有这个jcontrol脚本，很可能是因为所使用的JDK版本较低（beta8.2以前都没有这个脚本）。不用惊慌，只是稍微费事一点，运行下面的命令即可，功能和jcontrol脚本是完全相同的：
$ /opt/j2sdk-image/jre/bin/java /
-Djavaplugin.user.profile= -Xbootclasspath/a:/opt/j2sdk-image/jre/bin/../lib/deploy.jar /
com.sun.deploy.panel.ControlPanel
没找到deploy.jar文件，网上下载后继续。
执行上述命令时出现错误：
java.lang.UnsatisfiedLinkError: com.sun.deploy.config.WinConfig.getPlatformUserHomeImpl()[B
at com.sun.deploy.config.WinConfig.getPlatformUserHomeImpl(Native Method)

暂时未找到解决方法。
