Implementing Log4J on PCF related Java class

Step1:

Create a java project in Eclipse with name  GETCLUSQMGR.

Step2:

By default  we have a "src" folder  under  this folder  create a package by name com.logger.test and place the java classes with PCF,Logger  business logic.

Step3:

Create a source folder by name "resource" and add log4j2.xml file under it.

Step4:

Now the folder structure of the java project  will look like below

Step5:

Add the below code to ClusQmgr.java

package com.logger.test;

import java.io.IOException;

import org.apache.logging.log4j.Logger;

import com.ibm.mq.constants.CMQC;

import com.ibm.mq.constants.CMQCFC;

import com.ibm.mq.constants.MQConstants;

import com.ibm.mq.headers.pcf.PCFException;

import com.ibm.mq.headers.pcf.PCFMessage;

import com.ibm.mq.headers.pcf.PCFMessageAgent;

import com.ibm.mq.headers.MQDataException;

public class ClusQmgr

{     

static final Logger    logger      = CodeLogger.getLogger(ClusQmgr.class.getName());

public static void main (String [] args) throws MQDataException,PCFException, MQDataException,IOException

    {

              logger.debug("PCFMessageAgentCreation Start");

               PCFMessageAgent agent = new PCFMessageAgent("EB310000");

               logger.debug("Inquiring Cluster Queue Managers");

                PCFMessage pcfCmd = new PCFMessage(CMQCFC.MQCMD_INQUIRE_CLUSTER_Q_MGR);

                  pcfCmd.addParameter(CMQC.MQCA_CLUSTER_Q_MGR_NAME,"*");

      

                  logger.debug("Cluster Queue Managers Details");

                PCFMessage[] pcfResponse =agent.send(pcfCmd);

        System.out.println("**QueueManager**Host**Port**");

         String ClustQmgr=" ";

         String[] ConDetails;

         String Hostname=" ";

         String Port=" ";

 for (PCFMessage pcfMessage : pcfResponse)

{

     ClustQmgr=pcfMessage.getParameterValue(CMQC.MQCA_CLUSTER_Q_MGR_NAME).toString().trim();

      ConDetails=(pcfMessage.getParameterValue(MQConstants.MQCACH_CONNECTION_NAME).toString().trim()).split("\\(",2);

     Hostname=ConDetails[0];

     Port=ConDetails[1].substring(0,ConDetails[1].length()-1 );

      System.out.println("*****"+ClustQmgr+"*******"+Hostname+"*********"+Port+"**********");

      logger.debug("Values"+"**"+ClustQmgr+"**"+Hostname+"**"+Port+"**");

                    

       }

    logger.debug("End of PCF Details");

}

}

Step6:

Add the below code to CodeLogger.java

package com.logger.test;

import org.apache.logging.log4j.LogManager;

import org.apache.logging.log4j.Logger;

import org.apache.logging.log4j.core.config.ConfigurationFactory.ConfigurationSource;

import org.apache.logging.log4j.core.config.Configurator;

public final class CodeLogger {

     

private static final String   LOG4J_CONFIG_FILE = "log4j2.xml";

     

static

{

ConfigurationSource source = new ConfigurationSource();

source.setInputStream(CodeLogger.class.getClassLoader().getResourceAsStream(LOG4J_CONFIG_FILE));

Configurator.initialize(CodeLogger.class.getClassLoader(), source);

}

     

public static Logger getLogger(String name)

{

return LogManager.getLogger(name);

}

}

Step7:

Add the below properties  to log4j2.xml

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

<configuration>

<properties>

<property name="logFileDir">C:\\LOG4J\\</property>

<property name="logFileName">logger</property>

</properties>

<appenders>

             

<RollingFile name="RollingFile" fileName="${logFileDir}${logFileName}.log"

                     filePattern="${logFileDir}$${date:yyyy-MM}/${logFileName}-%d{yyyy-MM-dd}-%i.log.gz">

<PatternLayout pattern="[%d{ISO8601}] [%t] %-5p %c{6} - %msg%n" />

<Policies>

<TimeBasedTriggeringPolicy />

<SizeBasedTriggeringPolicy size="1 MB" />

</Policies>

</RollingFile>

</appenders>

<!-- Logging done on particular package bases "com.logger.test"-->

<loggers>

<logger name="com.logger.test" additivity="false" level="DEBUG">

<AppenderRef ref="RollingFile" />

</logger>

</loggers>

</configuration>

Step8:

Add the below jars to the Java Build Path of the project

log4j-api-2.0-rc1.jar, log4j-core-2.0-rc1.jar

Step9:

OutPut of the logger file will look like below
