Protege OntoGraf 插件无法工作

Question

我正在 Protege IDE 中开发本体，但插件 OntoGraf 对我不起作用。请帮我解决这个问题。下面你会看到堆栈跟踪：

Answer 1

不幸的是我需要使用 Sun 的 Java 来使用这个插件。我的 Linux 发行版（Debian GNU/Linux 6.0）安装了 OpenJDK，它不包含 sun 软件包。
当我更新目录 /etc/alternatives 中的链接 java* 时，我解决了这个问题。
对于 debian 来说很简单，使用命令即可：

 update-alternatives --config java
 update-alternatives --config javac
 update-alternatives --config javaws
 update-alternatives --config jar
 end etc..
