Activate simple logging for a bundle [message #846132]

Dear all,

I am quite stuck Sad

...

I have created a bundle, but logging doesn't work and I don't know how I can activate it...

I have tried to use sl4j-api or just System.out.println, I searched through all log.log files, but my logging is nowhere. I have also tried to add a logback.xml file with logback configuration to the root of the jar, which however also didn't work...

Please, could anybody help me how to activate logging for a simple bundle (no par or plans)!

Did you edit config[uration]/serviceability.xml to enable an appropriate level of trace?

I didn't change anything from the default config. I added the following logback.xml to the root of the bundle (jar)...

<?xml version="1.0" encoding="UTF-8"?>

<configuration>

  <appender name="STOUT" class="ch.qos.logback.core.ConsoleAppender">
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>

  <root level="info">
    <appender-ref ref="STOUT" />
  </root>
</configuration>

I must admit, that I am no expert in the logback configuration, if you could tell me what to add to the defaul config would be great!

Please see the excellent logback manual, specifically this section.

My solution how I activited logging for a bundle is as follows:

Adding a logback.xml to the root of the bundle
Referencing the org.eclipse.virgo.medic.eventlog.EventLogger service within the spring container definition
Adding the Import Statement for the org.eclipse.virgo.medic.eventlog Package in the Manifest

if there is a better approach, please inform me...
