Client/Server Based Application Using a C/Java Interface

摘要

Since 1995, the Naval Research Laboratory (NRL) at the Stennis Space Center (NRLSSC) has been developing and enhancing a software application that allows naval AV-8B and F/A-18 aircraft mission planners and aircrew to design and build digital aeronautical chart coverages for cockpit moving-map displays. The application, known as the Moving-Map Composer (MMC), currently is implemented in the X-Windows graphical user interface (GUI) language and the C programming language. Currently, MMC is only supported on Compaq Alpha computers running the OpenVMS operating system. This limitation requires end users to acquire Alpha stations, which are more expensive than standard Intel-based PC platforms. This paper will discuss reengineering methods being developed by NRLSSC to transform the existing MMC application to a Java and C-based program that will execute on many different hardware platforms and operating systems, including Linux, Windows NT and OpenVMS.
