Exception in thread "main" java.lang.NoClassDefFoundError: javax/comm/NoSuchPortException

Caused by: java.lang.ClassNotFoundException: javax.comm.NoSuchPortException

	at java.net.URLClassLoader$1.run(URLClassLoader.java:217)

	at java.security.AccessController.doPrivileged(Native Method)

	at java.net.URLClassLoader.findClass(URLClassLoader.java:205)

	at java.lang.ClassLoader.loadClass(ClassLoader.java:319)

	at java.lang.ClassLoader.loadClass(ClassLoader.java:264)

	at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:332)

Could not find the main class: BlackBox. Program will exit.
