I’ve been struggling a bit with Java on Windows when I have needed to load a native library required by the application I’m currently working on (believe it or not a Java desktop application. Yes they still exist! 🙂 There are several options:
- Load from an explicitly specified absolute path using the System.load call.
- Make sure the DLL is in one of the paths listed in “java.library.path”
Handy tip: if running IntelliJ grab the code from and use it for a new Scratch file. It’s an easy way to get the value for your java.library.path.
- Modify the Windows system PATH environment variable to include the folder where the DLL is stored.
- Passing the “java.library.path” on the command line to the java runtime by using the -D option.
