I have developed a project with swing, maven with some native libraries. Now i have an issue with calling SO from java after generating jar from maven package. I included so in POM.xml. And it included that file inside jar.But it wont link both.

I had an error while executing jar like " Exception in thread "main" java.lang.UnsatisfiedLinkError: no projectso in java.library.path"

 <resources>
       <resource>
         <filtering>false</filtering>
         <directory>${project.basedir}/lib</directory>
         <includes>
           <include>my.so</include>
           <include>cv2.so</include>
         </includes>
       </resource>
   </resources>

And also want to add library folder and export it into jar.Is there any way to do it?

Your native library path is not correct for your program to run. see Call c function from Java

use -Djava.library.path=/path/to/libs to set the path before executing the program.

use System.loadLibrary("HelloWorld") to set the path in runtime

please take look at the link I post again.

  • Yaa, I did this in my code. Still i'm getting the same error after making jar – praveenkumar s Nov 09 '17 at 06:00
  • @praveenkumars print "java.library.path" in your log to make sure it's right – xxy Nov 09 '17 at 06:02
  • before built jar i'm getting the right path, after build the jar i'm getting the jdk lib path. How to resolve this? /home/hubino/torch/install/lib:/home/hubino/torch/install/lib::/usr/local/cuda-8.0/lib64:/home/hubino/Documents/software/cudnn/cudnn_5.1/lib64:/home/hubino/Videos/lib:/usr/java/packages/lib/amd64:/usr/lib/x86_64-linux-gnu/jni:/lib/x86_64-linux-gnu:/usr/lib/x86_64-linux-gnu:/usr/lib/jni:/lib:/usr/lib – praveenkumar s Nov 09 '17 at 06:08
  • Do you have any idea for changing this library path in jar? – praveenkumar s Nov 09 '17 at 09:28
