What is LD_LIBRARY_PATH and how to use it?

Question

I take part in developing a Java project, which uses some C++ components, thus I need Jacob.dll. (on Windows 7)

I keep getting java.lang.UnsatisfiedLinkError:

Answer 1

Well, the error message tells you what to do: add the path where Jacob.dll resides to java.library.path. You can do that on the command line like this:

java -Djava.library.path="dlls" ...

(assuming Jacob.dll is in the "dlls" folder)

Also see java.lang.UnsatisfiedLinkError no *****.dll in java.library.path
