There are only two "native daemon" configurations I'm interested in: - embedded in Apache 2 with a JNI connector - used through jsvc on Unix, and some similar wrapper on Win NT (or jsvc.exe using Cygwin; it works :)) With Daemon, from the C code, all you have to do is, as Pier pointed out: - Call init - Use setuid to downgrade to nobody - Call start - Wait for a stop signal, at which point you call stop At this point, I do not see the need for any use of native code from the Java side.
