Solved: How do jacoZoom-generated Java-sources know where the native Library is located?

I generated java wrapper-classes for the DLL of the "Mercury Quality Center 9.0 API" (OTAClient.dll) with JacoZoom.
By default, the wrapped DLL file is located in "c:\program files\common files\Mercury Interactive\Quality Center",
but my application should have the OTAClient.dll file in its own directory (the default path may be not accessible).

I could not find any option in JacoZoom to set the path of the wrapped DLL.
And regarding the generated java-sources, I could not find any information on how the DLL is found by the java classes.
My application only works if the OTAClient.dll file is located in the standard directory, otherwise I get Exceptions that the DLL could not be found.

Does anyone know, how JacoZoom-generated Java-sources know where the native library is located?

I attached a code snippet showing a class generated by JacoZoom.
"vtblCall()" is a method from the jacoZoom library, but it seems to me that this method gets the requested information from the DLL.
As that jacoZoom library is not generated while wrapping the native library, in my opinion, the parameters must be the key to the DLL and its method.
But I have no idea how.

Can anyone help me?
