首次在 Ubuntu 中使用 Java Web Start - 致命启动异常

我已经使用 Ubuntu 一段时间了，Java Web Start 应用程序在当前版本或任何以前的版本中都从未“正常工作”，所以我一直忽略它们，直到现在。但是，现在我需要让它们在 Firefox 中工作。当我在这样的页面上时：http://www.oracle.com/technetwork/java/demos-nojavascript-137100.html 我希望能够按照建议单击演示并运行它们。

我正在运行带有 Gnome 3 的 Ubuntu 11.10 和/或带有 OpenJDK 6、OpenJDK 7 和 Sun Java 6 的 Linux Mint 12（64 位）。我的默认设置当前为：/usr/lib/jvm/java-6-openjdk/jre/bin/java

$ whereis javaws
javaws: /usr/bin/javaws

/etc/alternatives/javaws->/usr/lib/jvm/java-6-openjdk/jre/bin/javaws

这是我尝试运行 Java Web Start 应用程序时收到的错误：

已解决：显然 Sun Java javaws 可以工作。在 Firefox 中：

编辑 > 首选项 > 应用程序 > “Java Web Start 应用程序” > 其他：

/usr/lib/jvm/java-6-sun/jre/bin/javaws
