We’ve been experiencing the same problem using Sun JVM 1.3.1_07 on W2K servers. We’ve had partial success. By placing the correct Jvm and JvmArgs Registry settings, (HKEY_LOCAL_MACHINE\Software\System\CurrentControlSet\Services\WmIS), we can at least get IS to show up as an NT Service. However, it is still not operational (Can’t point an wM Administrator page to it). We think that we just have to be more careful with the settings. If that is the case, we’ll let you know.
