Question

I’ve got a Maven project in NetBeans with various dependencies that allow me to plot some 3D charts/graphs (JOGL, Gluegen & JZY3D). These work fine if I run the project from NetBeans, but when I build the project into a JAR file, I get the following…

Exception in thread "Building 3D Scatter Plot" java.lang.UnsatisfiedLinkError: no gluegen-rt in java.library.path
    at java.lang.ClassLoader.loadLibrary(Unknown Source)
    at java.lang.Runtime.loadLibrary0(Unknown Source)
    at java.lang.System.loadLibrary(Unknown Source)
    at com.jogamp.common.jvm.JNILibLoaderBase.loadLibraryInternal(JNILibLoaderBase.java:442)

Is this an issue with Maven/NetBeans not building the JAR with all the correct dependencies or have I missed something here?

Answer 1

In my opinion, it is searching for a dll (gluegen-rt.dll), which should be in the java library path.

You could add a dll dependency (you’ll need to manually add it in your repo or Nexus):

<dependency>
    <groupId>gluegen-rt</groupId>
    <artifactId>gluegen-rt</artifactId>
    <type>dll</type>
</dependency>
