  • Debugging iSeries Java Applications Remotely

    May 17, 2006 Mike Brown

    IBM has provided several approaches for debugging Java applications on the iSeries, such as the IBM iSeries System Debugger. However, if you are an experienced Java developer, yet not experienced with the iSeries, you might find these tools and their instructions for use a little intimidating.

    One alternative might be the Java Debugger (jdb) provided with most Java Development Kits. This is a command line utility that supports breakpoints, stepping through your application and examining objects. Unfortunately, IBM does not provide this tool on the iSeries.
