can we interact with RPG pgm without changing the code. i guess we can use adapter class for the purpose but i haven't grasp the idea how to trap the screens and it's values moreover how to give data to the rpg pgm. which it expects to get from the user through the display files. you talked about jdqm/400 could you give some details about it. my general query is how to wrap around the existing rpg code. thanks , Rahul email@example.com on 09/01/99 02:03:42 AM Please respond to JAVA400-L@midrange.com To: JAVA400-L@midrange.com cc: (bcc: Rahul Dwivedi/LTITLVSH) Subject: RE: doing things backwards >Thanks, Joe. At least now I know. Actually data queues seem like a >reasonable alternative. ---------- Actually, data queues can be used pretty profitably, especially if you're willing to write a batch server. If you submit the Java program (actually submitting a call to QSH) and have it wait on a data queue for requests, you'll only have to suffer through JVM initialization once, and from then on the systems runs pretty well. If you download PBD1.2P, there's a package JDQM/400 which consists of Java classes which wrapper RPG programs which in turn wrapper the data queue APIs. Why this indirection? Because it allows RPG and Java to talk to one another in either direction. Java clients on the workstation can talk to RPG servers on the AS/400, or RPG clients on the AS/400 can talk to submitted Java servers on the AS/400, or any combination in between. To create a Java server, you simply subclass the JdqmServer class, put in your own run() method, and you're off to the races. There's a fully functional demo program, as well as the appropriate RPG and CL programs in a library (in a save file). Go to http://www.zappie.net/java/techniques/pbd.htm to download it.
