Hi Nacho,
The this configuration of logback works for you?
I've tried to do the same, with the following versions of
logback: logback-classic-0.9.24.jar, logback-core-0.9.24.jar,
slf4j-api-1.6.1.jar
With the following configuration of backlog.xml:
cat WEB-INF/classes/logback.xml
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<!-- <pattern>%-5level %logger{0} - %msg%n</pattern> -->
<pattern>%-5level %logger{36} - %msg%n</pattern>
</encoder>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>ERROR</level>
<onMatch>DENY</onMatch>
<onMismatch>ACCEPT</onMismatch>
</filter>
</appender>
<appender name="STDERR" class="ch.qos.logback.core.ConsoleAppender">
<target>System.err</target>
<encoder>
<pattern>%-5level %logger{0} - %msg%n</pattern>
</encoder>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>ERROR</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
</appender>
<root level="INFO">
<appender-ref ref="STDOUT" />
<appender-ref ref="STDERR" />
</root>
And I'm getting the following exception when my code tries to create a new
Logger:
Failed to instantiate [ch.qos.logback.classic.LoggerContext]
Reported exception:
java.lang.NoClassDefFoundError: java.net.InetAddress is a restricted class.
Please see the Google App Engine developer's guide for more details.

Now, before I go dig any further into how to work around this, could you
please share your experience with this issue?
Thanks,
Maxim.
