About JPOS Drivers for Windows and Linux

Overview

The POS application is either a Java application or an applet that uses one or more JavaPOS devices. An application accesses the JavaPOS device through the JavaPOS Device Interface, which is specified by Java interfaces.

Each JavaPOS device is a combination of these components:

  • JavaPOS Device Control is a Java class that provides the interface between the application and the device category. It contains no graphical component and is therefore invisible at runtime and conforms to the JavaBeans API. The Device Control was designed so that all implementations of a device category's control are compatible. The Device Control can be developed independently of a Device Service for the same device category. They may even be developed by different companies.
  • JavaPOS Device Service is a Java class that is called by the Device Control through the JavaPOS Device Service Interface. The Device Service is used by the Device Control to implement JavaPOS-prescribed functionality for a physical device. It can also call special event methods provided by the Device Control to deliver events to the application.
  • The JPOS driver included with the Zebra Scanner SDK for Windows provides JNI (Java Native Interface) mechanisms to scanner and scale devices (CSJPOSScanner.dll and CSJPOSScale.dll) for the JavaPOS Device Service layer to interface with the CoreScanner driver.
