Eclipse VM Argument and external JAR file error

Question

I just added "-Djava.library.path=" to the "VM Arguments" under Run Configuration in Eclipse and everything works fine until I tried to add an external JAR file. I get the following error:

java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path thrown while loading gnu.io.RXTXCommDriver
Exception in thread "main" java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path

Am I not setting something properly in Eclipse?

Answer 1

Appearently that external library has a dependancy with another class gnu.io.RXTXCommDriver . Perhaps you will need to add that library to class path.

Answer 2

The exception indicates that the class gnu.io.RXTXCommDriver tries to load a native library, which would be named rxtxSerial.dll on Windows and rxtxSerial.so on Linux, and the JVM cannot find it in the directories listed in java.library.path. Have you tried to add a JAR containing the library to java.library.path? I don't think that's possible, it has to be a directory containing the extracted library file.
