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/Linux6.0)是与OpenJDK一起安装的，它不包含sun包。我修复了这个问题，当我更新/etc/alternatives目录中的链接java*时。对于debian来说很简单，可以用命令来实现：

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