How to programmatically set the loading path of dynamic libraries in java?

System.setProperty("java.library.path", "pathToLibs");

doesn't work because it seems either "java.library.path" is read only or JVM just ignores the property.

I know it can be done by setting PATH(in windows), LD_LIBRARY_PATH(in POSIX) or just use the command java -Djava.library.path=your_path.

But is there a programming way of doing this?

java.library.path is evaluated when the VM starts, so changing it later does not have any effect on loading native libraries. You can however use System.load(String filename); to specify the complete path to the native library you want to load, perhaps together with System.mapLibraryName(String) to add the platform specific file ending (e.g. .dll or .so).
