java.library.path - Default Java library path?

Question

I understand that you can set the Java library path with an option (-Djava.library.path=/path/to/libs) before executing the program, but is there a place on the system where Java looks if you don't set it manually?

Answer 1

Its default value depends on the operating system:

• On Windows, it maps to PATH
• On Linux, it maps to LD_LIBRARY_PATH
• On OS X, it maps to DYLD_LIBRARY_PATH
