Creating custom logger files for your portlet and also default logger file for server

Creating custom logger files for your portlet and also default logger file for server .

Disabling console appender .

Step 1:Create a  ext portlet  using liferay IDE .

Step 2: create a META-INF folder under ext-impl/src   (src) and  create a portal-log4j-ext .xml  add log4j.dtd file

   Example: portal-log4j-ext .xml 

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

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

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

      <!-- additional custom logging -->

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

            <param name="File" value="${catalina.base}/logs/srikanthcustom.log"/>

             

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

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

            </layout>

      </appender>

     

      <!-- general application log -->

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

            <param name="File" value="${catalina.base}/logs/liferay.log"/>

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

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

            </layout>

      </appender>

<!—Custom portlet logging -->

      <category name="com.test.sample">

            <priority value="INFO" />

            <appender-ref ref="file"/>

      </category>

     

     

     

<!-- default logging -->

      <root>

            <priority value="INFO" />

            <appender-ref ref="liferayFile"/>

      </root>

</log4j:configuration>

Explaination: The above code will create a 2 log file under server(tomcat)\logs

1:liferay.log as default log file,It appends all the default logs .

2: srikanthcustom.log (newsroom in example below)file,this file appends only logs from the package which are metioned in the category,as shown below.

<category name="com.test.sample">

            <priority value="INFO" />

            <appender-ref ref="file"/>

      </category>

     

Note: Once you create the ext portlet ,after deploying wait for few seconds and then restart the server to see the effects.
