no rxtxSerial in java.library.path thrown while loading gnu.io.RXTXCommDriver in Mac OS 10.12.2

I am developing an application in Java using Eclipse IDE. My os is Mac OS 10.12.2 . My application is using the RXTX library (gnu.io.*) for serial communication, added in my pom.xml

<dependency>
            <groupId>org.rxtx</groupId>
            <artifactId>rxtx</artifactId>
            <version>2.1.7</version>
</dependency>

I have added also librxtxSerial.jnilib file in project by doing this (project->Properties->java buld path->addjars). whenever I run my code it gives me this 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

Solution

  • You have to add the location of the folder that contains librxtxSerial.jnilib as Native library location:

    1. Right-click project and choose Properties
    2. In Java Build Path, in the Libraries expand the RXTX JAR node
    3. Select the subnode Native library location: (None) and click Edit
    4. Enter the folder location that contains librxtxSerial.jnilib and click OK
