We are re-engineering an older application into being web based. The original application is written in COBOL and uses wireless devices that communicate with the UNIX host. The processing actually happens on the UNIX in COBOL and only the screens and associated data are passed to the radios. We need to do this in the newer technologies. There is an underlying UNIX COBOL based system as well. When we are done, this system will be a 5-tier architecture, web-based written in JAVA. Any information or hints out there on what we do with the wireless side?
