I am trying to use jsvc to launch my program on Ubuntu 12.10 with Java 7:
$ java -version
java version "1.7.0_15"
OpenJDK Runtime Environment (IcedTea7 2.3.7) (7u15-2.3.7-0ubuntu1~12.10)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
With the -debug flag, jsvc reports that it correctly finds and loads the JVM
shared lib:
/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server/libjvm.so
At the very end of the log, jsvc reports the following:
Java VM created successfully
Cannot find daemon loader org/apache/commons/daemon/support/DaemonLoader
java_init failed
I am not surprised that jsvc can't find DaemonLoader, since I only built the
native part of commons-daemon. However, I thought I understood from the docs
that I didn't need DaemonLoader if the entry point class on the jsvc command
line implemented the magic four methods. The public interface of my entry
point class looks like this:
public class JettyDaemon {
public void init(String[] args) { ... }
public void start() { ... }
public void stop() { ... }
public void destroy() { ... }
}
Why does jsvc not load and execute this class directly? Is there a way to get
jsvc to print diagnostics about the loading process? Or is it the case that
jsvc requires the DaemonLoader Java class to be available?
Thanks,
Ian
