Yes, you must also add the library path to the wrapper.conf configuration file. Use the parameter wrapper.java.library.path
.
Probably you already have something like the following line in the wrapper.conf file:
wrapper.java.library.path.1=[?path?]/w32service/
Add this line:
wrapper.java.library.path.2=D:/Mendix/KentekengegevensLeasemij/WEB-INF/lib/
When the first library path does not exist, replace the '2' by '1'.
