How can I get Jsvc to find the DaemonLoader?
apache-commons, daemon, java, jsvc, service
Solution
You probably found the solution by now, but just in case someone stumble over this in the future, what I had missed in mine is that current directory defaults to '/', so you have to specify it if you want to use relative paths.
sudo jsvc -jvm server -cwd /path/to/my/daemon/ -cp commons-daemon-1.0.15.jar:./api-monitor.jar ApiMonitorDaemon
Note: my OS is ubuntu 12.10
Problem
I have the `commons-daemon-x.jar` in the `classpath`. The Jsvc is successfully launching the Java VM. But `jsvc` is reporting that it cannot find the daemon loader class even though it is in the `classpath`. Does anyone know how to solve this problem? I’m running Mac OS X 10.8.3. Thanks. Here's an excerpt of the `jsvc` debug output: ``` ... +-- DUMPING JAVA VM CREATION ARGUMENTS ----------------- | Version: 0x010004 | Ignore Unrecognized Arguments: False | Extra options: 1 | "-Djava.class.path=commons-daemon-1.0.15.jar:./api-monitor.jar" (0x00000000) +——————————————————————————— ...
