解决Ubuntu下安装Flex_Builder_for_linux:java.awt.HeadlessException

今天在我的Ubuntu下安装flex_builder_for_linux:出现了下面的一个错误，一直没找到原因，因为我路径什么的都是配置好了的，但是就是无法安装，不管是在root下还是什么 。
错误：

Invocation of this Java Application has caused an InvocationTargetException. This application will now exit. (LAX)

我自己的JDK版本是1.6.0_24的，官方下载的最新版本，但是呢由于Ubuntu默认安装了open-jdk，所以导致了这次安装失败。

接下来，配置一下Ubuntu默认的jdk为我们自己手动安装的 jdk版本。

#sudo update-alternatives --install /usr/bin/java java 你jdk安装目录/bin/java 300
#sudo update-alternatives --install /usr/bin/javac javac 你jdk安装目录/bin/javac 300

接下来运行如下代码：配置你的jdk

#sudo update-alternatives --config java

运行后，选择你的jdk编号，回车就可一了，接下来继续安装你的程序吧，看看问题是否解决了呢 。
