Chuk-Munn Lee of Sun Microsystems Troubleshoots Java SE 6 Deployment

This article is adapted from a talk that Sun Microsystems Java technology evangelist Chuk-Munn Lee presented at Sun Tech Days in Sydney, Australia, in March 2008. Based in Singapore, Lee works frequently with individual developers and software vendors, helping them to architect and prototype both their server and desktop-based Java applications. His more recent work has focused on Swing-based client applications. He also keeps ISVs up-to-date on the latest developments in the Java platform and what's on the horizon.

The talk explored ways to troubleshoot running Java applications, with a focus on Java SE 6.
