Java agent to transfer lotus notes documents to sqlite doesn't find library

I am currently using sqllite-jdbc-3.8.11.1.jar in my Java beans to update records in a local sqlite db. That works perfectly fine but the problem is when I try to use the same jar file in a Java agent I get this error message:

java.lang.Exception: No native library is found for os.name=Windows and os.arch=x86_64

I checked the jar file and the dll is definitely there.

I have included the jar file in the build path. I added it also as archive in the Java agent but I can't find a reason why it would work in the XPages runtime but not in a Java agent runtime.
