Class Daemon

java.lang.Object

com.google.enterprise.adaptor.Daemon

All Implemented Interfaces:

Daemon

public class Daemon
extends Object
implements Daemon

Allows running an adaptor as a daemon when used in conjunction with procrun or jsvc.

Example execution with jsvc:

jsvc -pidfile adaptor.pid -cp someadaptor-withlib.jar \
    com.google.enterprise.adaptor.Daemon package.SomeAdaptor

Example registration with prunsrv, the procrun service application:

prunsrv install someadaptor --StartPath="%CD%" ^
  --Classpath=someadaptor-withlib.jar ^
  --StartMode=jvm --StartClass=com.google.enterprise.adaptor.Daemon ^
  --StartMethod=serviceStart --StartParams=package.SomeAdaptor
  --StopMode=jvm --StopClass=com.google.enterprise.adaptor.Daemon ^
  --StopMethod=serviceStop

Where someadaptor is a unique, arbitrary service name.

Typical setups will also want to provide extra arguments with procrun:

prunsrv ... ^
   --StdOutput=stdout.log --StdError=stderr.log ^
   ++JvmOptions=-Djava.util.logging.config.file=logging.properties
