Javafx error on Ubuntu while using netbeans - linux

Question

When trying to run a basic javafx application on ubuntu linux, I am seeing the following error. The error appears while using either the commandline or netbeans to run the application.
Exception in thread "main" java.lang.RuntimeException: java.lang.UnsatisfiedLinkError: Can't load library: /home/venkat/.m2/repository/com/oracle/javafx/javafx/2.1.0-beta/i386/libglass.so

Answer 1

This exception is caused because maven is unable to find the native libraries on the classpath.
Netbeans
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/
Image
Command line
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/
The first two env variables above fix a classpath problem which is seen when javafx runtime cannot be found.
