解决方案

导致此异常是因为maven无法在类路径中找到本机库。

This exception is caused because maven is unable to find the native libraries on the classpath.

Netbeans

您可以通过在运行中添加JVM参数来解决问题个人资料。

You can solve the problem by adding JVM argument inside the run profile.

-Djava.library.path = / home / venkat / Programs / javafx / 2.1.0-beta / rt / lib / i386 /

命令行

如果您在尝试在命令行上运行应用时遇到同样的问题，则以下导出应修复它。

If you face the same problem while trying to run the app on the commandline, the following exports should fix it.

export JAVAFX_HOME=/home/venkat/Programs/javafx/2.1.0-beta

export CLASSPATH=\$JAVAFX_HOME/rt/lib/jfxrt.jar

export LD_LIBRARY_PATH=/home/venkat/Programs/javafx/2.1.0-beta/rt/lib/i386/

上面的前两个env变量修复了无法找到javafx运行时时出现的类路径问题。

The first two env variables above fix a classpath problem which is seen when javafx runtime cannot be found.
