cannot get SLF4J working with glassfish 4

Question

I have configured glassfish 3 to use SLF4J in the past by using the SLF4J JUL bridge and it worked fine. The problem I'm having now is that if I use my same setup, SLF4J complains about there being duplicate SLF4J bindings on the classpath and after searching, glassfish itself contains those reference.

How do I get SLF4J working? I tried making my dependency upon the SLF4J-API as provided, and then removed LogBack Classic since glassfish already contains some logback code. Doing those things doesn't yield any successful results.

This may helps you

Download Glassfish 4, SLF4J and Logback

Stop gf4

$GF_INSTALL\bin>asadmin stop-domain

and then

Copy

• jul-to-slf4j-1.7.5
• slf4j-api-1.7.5
• logback-core-1.0.13
• logback-classic-1.0.13

to

$GF_INSTALL/glassfish/lib/endorsed

Create logback.xml in

$GF_INSTALL/glassfish/domains/domain1/config

containing

<configuration debug="true" scan="true">
    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
        <file>/tmp/gf_server.log</file>
        <append>true</append>
        <encoder>
            <Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{52} - %msg%n</Pattern>
        </encoder>
    </appender>
    <root>
        <level value="INFO"/>
        <appender-ref ref="FILE"/>
    </root>
</configuration>

Modify

$GF_INSTALL/glassfish/domains/domain1/config/logging.properties

and replace

handlers=java.util.logging.ConsoleHandler
handlerServices=com.sun.enterprise.server.logging.GFFileHandler
java.util.logging.ConsoleHandler.formatter=com.sun.enterprise.server.logging.UniformLogFormatter
com.sun.enterprise.server.logging.GFFileHandler.formatter=com.sun.enterprise.server.logging.ODLLogFormatter

com.sun.enterprise.server.logging.GFFileHandler.flushFrequency=1
java.util.logging.FileHandler.limit=50000
com.sun.enterprise.server.logging.GFFileHandler.logtoConsole=false
com.sun.enterprise.server.logging.GFFileHandler.rotationLimitInBytes=2000000
com.sun.enterprise.server.logging.GFFileHandler.excludeFields=
com.sun.enterprise.server.logging.GFFileHandler.multiLineMode=true
com.sun.enterprise.server.logging.SyslogHandler.useSystemLogging=false
java.util.logging.FileHandler.count=1
com.sun.enterprise.server.logging.GFFileHandler.retainErrorsStasticsForHours=0
log4j.logger.org.hibernate.validator.util.Version=warn
com.sun.enterprise.server.logging.GFFileHandler.maxHistoryFiles=0
com.sun.enterprise.server.logging.GFFileHandler.rotationOnDateChange=false
java.util.logging.FileHandler.pattern=%h/java%u.log
java.util.logging.FileHandler.formatter=java.util.logging.XMLFormatter

with

handlers=org.slf4j.bridge.SLF4JBridgeHandler
handlerServices=com.sun.enterprise.server.logging.GFFileHandler
java.util.logging.ConsoleHandler.formatter=com.sun.enterprise.server.logging.UniformLogFormatter
com.sun.enterprise.server.logging.GFFileHandler.formatter=com.sun.enterprise.server.logging.ODLLogFormatter
com.sun.enterprise.server.logging.GFFileHandler.file=/tmp/server.log
com.sun.enterprise.server.logging.GFFileHandler.rotationTimelimitInMinutes=0
com.sun.enterprise.server.logging.GFFileHandler.flushFrequency=1
java.util.logging.FileHandler.limit=50000
com.sun.enterprise.server.logging.GFFileHandler.logtoConsole=false
com.sun.enterprise.server.logging.GFFileHandler.rotationLimitInBytes=2000000
com.sun.enterprise.server.logging.GFFileHandler.excludeFields=
com.sun.enterprise.server.logging.GFFileHandler.multiLineMode=true
com.sun.enterprise.server.logging.SyslogHandler.useSystemLogging=false
java.util.logging.FileHandler.count=1
com.sun.enterprise.server.logging.GFFileHandler.retainErrorsStasticsForHours=0
log4j.logger.org.hibernate.validator.util.Version=warn
com.sun.enterprise.server.logging.GFFileHandler.maxHistoryFiles=0
com.sun.enterprise.server.logging.GFFileHandler.rotationOnDateChange=false
java.util.logging.FileHandler.pattern=%h/java%u.log
com.sun.enterprise.server.logging.GFFileHandler.formatter=com.sun.enterprise.server.logging.UniformLogFormatter
com.sun.enterprise.server.logging.GFFileHandler.alarms=false

Add this two new JVM options to

domain->configs->config->java-config

in

$GF_INSTALL/glassfish/domains/domain1/config/domain.xml

<jvm-options>-Djava.util.logging.config.file=${com.sun.aas.instanceRoot}/config/logging.properties</jvm-options>
<jvm-options>-Dlogback.configurationFile=file:///${com.sun.aas.instanceRoot}/config/logback.xml</jvm-options>

then start gf4 again

$GF_INSTALL\bin>asadmin start-domain
