I also had the same problem. It was resolved by putting below .dll into ../java(version)/jre/bin folder:

AspriseOCR.dll, AspriseJTwain.dll, DevIL.dll, ILU.dll

you have to add the dll path into your System path. you can use following code to add dll file into your system path

    System.setProperty( "java.library.path", "DriveName:/native/dll-folder/" );
    Field fieldSysPath = ClassLoader.class.getDeclaredField( "sys_paths" );
    fieldSysPath.setAccessible( true );
    fieldSysPath.set( null, null );
