log4j configuration in hazelcast.

[srikalyan swayampakula]

Hi Everyone,

I am trying to configure hazelcast to use log4j with log4j.properties/log4j.xml nothing seems to be working. I am getting this error

INFO: Using configuration file at /Users/srikalyan.swayampakula/tools/hazelcast/hazelcast-3.2.3/bin/hazelcast.xml

log4j:WARN No appenders could be found for logger (com.hazelcast.instance.DefaultAddressPicker).

log4j:WARN Please initialize the log4j system properly.

log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

I am runnning the following command

java -server -Xms1G -Xmx1G -Djava.net.preferIPv4Stack=true -cp ../lib/hazelcast-3.2.3.jar:../lib/log4j-1.2.17.jar -Dlog4j.configurationFile=./log4j.xml com.hazelcast.examples.StartServer

with hazelcast containing 

<properties>

<property name="hazelcast.logging.type">log4j</property>

</properties>

and this is my log4j.xml file

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration debug="true"

                     xmlns:log4j='http://jakarta.apache.org/log4j/'>

   <appender name="consoleAppender" class="org.apache.log4j.ConsoleAppender">

      <layout class="org.apache.log4j.PatternLayout">

         <param name="ConversionPattern" value="%d{dd MMM yyyy HH:mm:ss} %5p %c{1} - %m%n"/>

      </layout>

   </appender>

   <appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">

      <param name="append" value="false"/>

      <param name="file" value="out/learning.log"/>

      <layout class="org.apache.log4j.PatternLayout">

         <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n"/>

      </layout>

   </appender>

   <root>

      <level value="DEBUG"/>

      <appender-ref ref="consoleAppender"/>

      <appender-ref ref="fileAppender"/>

   </root>

</log4j:configuration>

Please let me know if I am doing something wrong.

Thanks in advance.

Can you add the following to the commandline:

-Dlog4j.debug

This should give you additional logging debug information.

And try to use the following syntax for the logfile

-Dlog4j.configurationFile=file:/log4j.xml 

I think the lack of file:/ prefix is causing the problem.

Personally I don't configure log4j from the config file, but do it on the commandline:

-Dhazelcast.logging=log4j

This is more reliable.

Thanks peter,

Running this worked 

{code}

java -server -cp /usr/lib/hazelcast/hazelcast.jar:/usr/lib/hazelcast/log4j.jar -Dhazelcast.config=/etc/hazelcast/hazelcast.xml -Dlog4j.configuration=file:///etc/hazelcast/log4j.properties -Dhazelcast.logging.type=log4j com.hazelcast.examples.StartServer

{code}

Problem was it was looking for configuration not configurationFile.

Just adding the note here so that it would be useful for future use.
