Usage Example

It's very easy to use, just like the way you use the original LogService.

Step1: import

import com.atlanssia.osgi.logservice.LogServiceExt;

Step2: Get the extended service from context in your bundle, and start use:

    ServiceReference ref = context.getServiceReference(LogServiceExt.class.getName());
        LogServiceExt log = null;
        if (ref != null)
        {
             log = (LogServiceExt) context.getService(ref);

            log.log(LogService.LOG_INFO, "Logged:hello atlanssia!");

            log.error("Log a exception", new Exception("Im a exception from Atlanssia"));
        }

Step3: Make sure the bundle logservice-x.x.x-SNAPSHOT.jar started before this bundle.

After all, take a look at the log file, it looks as below(with logback):
