C++Builder: Link error when calling a method from a Jar file

I'm developing a mobile app using C++ Builder Berlin 10.1 which use a Jar library to scan barcodes. With Java2OP, I obtained a Delphi Bridge File to use the functions of the Jar. I translated it to C++ and include it to my project with the associated Jar. Here are my files:

When I tried to use the functions like this :

    TJATScanLib* scan = new TJATScanLib();
    _di_JATScanLibClass scanner = scan->JavaClass->init();

C++ Builder raised this link error :
