I'm guessing you didn't install the dll with the packaging type "dll" (use -Dpackaging=dll, the default is jar - http://maven.apache.org/plugins/maven-deploy-plugin/usage.html). Check your local repository and the pom for the dll. Regarding your earlier question, you sure can package it into a jar and JNA's supposed to extract it out from the jar automatically if not found on library path but that was exactly your original problem: either it wasn't working or java.library.path wasn't set properly. Even with JNA, it's recommended practice to have the library in an accessible location on the system ( https://jna.dev.java.net/javadoc/com/sun/jna/Native.html#loadLibrary(java.lang.String,%20java.lang.Class))
