The records shown in the table are retrieved by calling a ILE RPG program on the AS/400. The subfile component contains one page maximum (full dynamic) Every user action is translated into calling a driver program with an input parameter containing program code, request code, view(index), key values first and last record, ... The driver calls the program needed which receives a request code (e.g. "PageDown") after which - key and other values are parsed - the file gets positioned at the correct position - the number of records are read (if possible) and values parsed - the result is send back as an output parameter The table component parses the record values and return codes (EOF, BOF, ...) to show the result on the screen. Without realizing this at the beginning this concept slowly developped into a framework which allows us to write overview-detail programs rather quickly. We made RPG skeleton sources and a java framework to be used whenever new programs have to be written. The only thing left to do is to write a generator that will generate java and rpg source code (using the framework) for overviews, details, commands, statistics and other types of programs. We only need some extra time...

I am attempting to write a java application that would display a customer list loaded from a db2 file. When the uses selects a customer it will then bring them to a customer detail screen. My question is, what is the best way to load this list. The method I used was just a dow not eof loop that appended items to a JList. This worked fine for my testing, with minimum records, but when you start to get into thousands and even hundreds of thousands of records it takes quite a long time to load. I don't expect to be able to get subfile load speeds(can I?) but there must be methods to allow the speeding up of this process. Has anybody ever done anything like this? Any help would be greatly appreciated Robert Upshall Professional Software of Amarillo (806) 358-8928 rupshall@psasoft.com _______________________________________________ This is the Java Programming on and around the iSeries / AS400 (JAVA400-L) mailing list To post a message email: JAVA400-L@midrange.com To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/cgi-bin/listinfo/java400-l or email: JAVA400-L-request@midrange.com Before posting, please take a moment to review the archives at http://archive.midrange.com/java400-l. -- [ ras01.jpg of type image/jpeg deleted ]
