Exception in thread "main" java.lang.NoClassDefFoundError: gnu/io/CommPortIdentifier

[aj22r]

I have RXTXcomm.jar in C:\Program Files (x86)\Java\jdk1.8.0_131\jre\lib\ext and rxtxSerial.dll in C:\Program Files (x86)\Java\jdk1.8.0_131\jre\bin but it still gives me the error

Please follow the installation instructions in http://rxtx.qbang.org/wiki/index.php/Installation_for_Windows
Also check that the SimpleJBurn is executed by the java version you have the rxtx lib installed for.
Hope that helps.

I have librxtx installed in my system but get the same error. Ah, I'm using Linux:
