Some native libraries reference other dynamically linked libraries.
Java will locate the initial JNI library using the Java library path,
but the secondary libraries are loaded using the default mechanism for the platform.
On Windows,
the system will first look in the current working directory
(The location of the wrapper.exe),
then it will look in the Windows system32 directory
and the Windows directory.
Finally, it will search the entire system PATH.
If both DLLs are located in your application's lib directory,
it may be necessary to add its location to your system path as follows.
The set.PATH is for Windows
and the set.LD_LIBRARY_PATH makes the configuration file cross platform
so it works on Unix systems as well.
set.PATH=..%WRAPPER_FILE_SEPARATOR%bin%WRAPPER_PATH_SEPARATOR%%PATH%
set.LD_LIBRARY_PATH=..%WRAPPER_FILE_SEPARATOR%bin%WRAPPER_PATH_SEPARATOR%%LD_LIBRARY_PATH%

Note that placing the secondary library on the PATH
rather than in the current working directory
has a risk that an old version of the library could be encountered first
in the Windows system32 directory
if it was installed by another application.
This is due to the order in which the system looks for the file.
This problem has been seen when working with SAP's JCO libraries
if other SAP applications are also installed on the system.
