Show Log4J2 Output in Eclipse Console

Question

I've been unable to configure my Web app project to show LOG4J2 output in the Eclipse Console. It goes to some tomcat log location.

Tried all the threads and nothing helped.

First, suppose the LOG4J2.XML is originally here: ./appconfig/dev/log4j2.xml

I followed an example and added this folder as a Library under Class Path, but that didn't work.

Then I tried this example with a -D param for the config file,

Also tried adding it to the location which DeploymentAssembly will move to WEB-INF/classes,

Nothing helped, I'm not getting my Eclipse Console output for this app for log.info / log.error, except for Hibernate-only output.

LOG4J2.XML:

<?xml version="1.0" encoding="utf-8"?>
<Configuration>
    <Appenders>
        <Console name="console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{DATE} [%X{sessionId}] %X{userId} %-5p %c{1}(Line %L) - %m%n"/>
        </Console>

        <RollingFile name="file" fileName="/local/content/tomcat/idp/logs/idp.log" append="true"
                     filePattern="/local/content/tomcat/idp/logs/idp.log.%i">
            <PatternLayout>
                <Pattern>%d{DATE} [%X{sessionId}] %X{userId} %-5p %c{1}(Line %L) - %m%n</Pattern>
            </PatternLayout>

        <Logger name="net.sf.ehcache" level="trace" additivity="false">
            <AppenderRef ref="file"/>
        </Logger>

        <Root level="info">
            <AppenderRef ref="console"/>
            <AppenderRef ref="file"/>
        </Root>

</Configuration>

Answer 1

We figured it out. We had to remove additivity="false" from the Log4J2.xml.

Thus, the file is without additivity=false

<?xml version="1.0" encoding="utf-8"?>
<Configuration>
    <Appenders>
        <Console name="console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{DATE} [%X{sessionId}] %X{userId} %-5p %c{1}(Line %L) - %m%n"/>
        </Console>

        <RollingFile name="file" fileName="/local/content/tomcat/idp/logs/idp.log" append="true"
                     filePattern="/local/content/tomcat/idp/logs/idp.log.%i">
            <PatternLayout>
                <Pattern>%d{DATE} [%X{sessionId}] %X{userId} %-5p %c{1}(Line %L) - %m%n</Pattern>
            </PatternLayout>
            <Policies>
                <SizeBasedTriggeringPolicy size="10 MB"/>
            </Policies>
            <DefaultRolloverStrategy max="10"/>
        </RollingFile>
    </Appenders>

    <Loggers>
        <Logger name="gov" level="debug">
            <AppenderRef ref="file"/>
        </Logger>

        <Logger name="org.springframework.orm" level="info">
            <AppenderRef ref="file"/>
        </Logger>

        <Logger name="org.hibernate.sql" level="info">
            <AppenderRef ref="file"/>
        </Logger>

        <Logger name="org.springframework.web" level="debug">
            <AppenderRef ref="file"/>
        </Logger>

        <Logger name="org.hibernate.type" level="info">
            <AppenderRef ref="file"/>
        </Logger>

        <Logger name="net.sf.ehcache" level="trace">
            <AppenderRef ref="file"/>
        </Logger>

        <Root level="info">
            <AppenderRef ref="console"/>
            <AppenderRef ref="file"/>
        </Root>
    </Loggers>
</Configuration>
