My log is not working

[davidpadilha]

Hello folks!

I have a jar file inside the war file that contains a log4j.properties inside META-INF ( already have tried to put one level above META-INF ):

# Root logger option
log4j.rootLogger=INFO, file

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender

#Redirect to Tomcat logs folder
#log4j.appender.file.File=${catalina.home}/logs/logging.log

log4j.appender.file.File=c:\\export\\logs\mylog.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

When i run maven to compile my projects, it runs unit tests and the log messages goes to file "mylog.log" but when i deploy on Wildfly 8.0 and try to log something, it only logs on server.log.

I'm missing some configuration but i couldn't figure what is missing.

I have read the documentation and added the tag <use-deployment-logging-config value="false"/> to standalone.xml but still not working. I already have tried to put the log4j.properties inside the war file but still not working.

Anyone could give me a hand to make my log works?

Thank in advance.

Hello,

   Can you attach a sample application which demonstrate your issue.  I tested with a simple WAR [1] which has a simple servlet with log4j.properties and it is able to log properly in it's own custom log.

   The WAR which i used has the following structure.

Log4j2DemoWebApp.war

|-- index.jsp

`-- WEB-INF

    |-- classes

    |   |-- log4j.properties

    |   |-- MyServlet.java

    |   `-- servlets

    |       `-- MyServlet.class

    |-- jboss-deployment-structure.xml

    |-- lib

    |   `-- log4j-1.2.16.jar

    `-- web.xml

The jboss-deployment-structure.xml  is used in order to exclude the log4j APIs which are offered by WildFly and to use the log4j jar which is placed inside the WEB-INF/lib.

<jboss-deployment-structure>
  <deployment>
    <exclusions>
      <module name="org.apache.log4j"/>
    </exclusions>
  </deployment>
</jboss-deployment-structure>

The log4j.properties us as following:

log4j.rootLogger=INFO, file

# Direct log messages to a log file

log4j.appender.file=org.apache.log4j.RollingFileAppender

log4j.appender.file.File=${jboss.server.log.dir}/test.log

log4j.appender.file.MaxFileSize=10MB

log4j.appender.file.MaxBackupIndex=10

log4j.appender.file.layout=org.apache.log4j.PatternLayout

log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

I think you're misunderstanding the use-deployment-logging-config attribute. Setting that to false tells the logging subsystem not to scan your deployment for your log4j.properties file. From what it looks like if you were to place your log4j.properties WAR/META-INF or WAR/WEB-INF/classes directory then it should work and leave the use-deployment-logging-config set to true it should work.

Also make sure you're not including log4j in your WAR/WEB-INF/lib directory either.

You can now do this in WildFly without having to exclude log4j, though that way still works. See https://docs.jboss.org/author/display/WFLY8/Logging+Configuration#LoggingConfiguration-Attributes and https://docs.jboss.org/author/display/WFLY8/How+To#HowTo-HowdoIuselog4j.propertiesorlog4j.xmlinsteadofusingtheloggingsubsystemconfiguration%3F for more details.

I've done all the process again and now it's working.

I was trying to make it work only using a log4j.properties inside the jar that is a dependency from my war. When i have moved the log4j.properties to war file, everything works.

Thanks for the help.
