This talk looked at Sun's claim of "Write Once, Run Anywhere" backed with actual experience. Tek-Tools has been working on a Storage Resource Management (SRM) product. Part of this project has been to develop a platform independent Java agent, which has to run on Windows NT, Windows 2000, Netware and various UNIX versions. Along the way, all kinds of surprising problems related to Java platform independence were discovered and overcome including Windows Blue Screens of Death (yes, Java code can cause a BSOD!) and Linux defunct processes. The talk will discuss these issues and solutions in technical detail.
