This topic applies to FRE for Linux and Windows .
To effectively use all functionality provided and ensure developing the cross-platform applications, ABBYY FineReader Engine includes the Java wrapper, which you can find in the distributive package. This wrapper is suitable for any platform supported by ABBYY FineReader Engine and allows you to implement the ready-to-use Java classes intended for working with the Engine library. These Java classes can be used directly from Java applications. However, using Java wrapper has specifics for each platform, see the table below to learn about platform difference.
