Hello Clément,
Here is the sample code I have to get the log service:
___________________________
@Requires
private LogService log;
@Requires
private LogReaderService lrs;
@Validate
public void start(){
lrs.addLogListener(new LogListener() {
public void logged(LogEntry entry) {
System.out.println("log "+entry.getMessage());
}
});
log.log(LogService.LOG_DEBUG, "starting");
}
____________________________
I also have the org.apache.felix.log bundle as the log implementation.
But still no logs on the console !
Have I missed something ?
