[slf4j-user] blog entry on JCL

[Matt Raible]

Thanks - that works!  However, I'd expect the logging to look the same
as it did before.  Unfortunately, it looks like the method isn't
printed out - just "info", "debug", etc.  Here's my log4j.xml
configuration:

    <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern"
                value="%p [%t] %c{1}.%M(%L) | %m%n"/>
        </layout>
    </appender>

commons-logging:

WARN [main] UserAction.save(157) | User 'tomcat' already exists!
INFO [main] UserActionTest.endTransaction(284) | Rolled back
transaction after test execution
INFO [main] UserActionTest.startNewTransaction(318) | Began

SLF4J:

Thanks,
