How can I configure the logging/How to turn off debugging messages

Configuring logging for the Pentaho-Report-Designer

The Pentaho Report-Designer ships with Log4J and therefore can be configured by placing a "log4j.xml" file into the "$(PRD-Installation-Dir)/resources" directory. In Pentaho Report-Designer 3.6, a properly configured log4j-configuration file exists already.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

Configuring the logging system for Pentaho Reporting Classic 0.8.10 and later

Since version 0.8.10, we use Apache-Commons-Logging for all Logging activities. If Log4J is on the Classpath, Apache-Commons-Logging will automatically use this logsystem and all logging activities must be configured via Log4J.

For development purposes, it can be useful to reroute all logging to System.err instead. For this, you need to have two properties file on your classpath:

In commons-logging.properties you configure the logging system to be used. The following configuration forces commons-logging to use System.err for all logging.

org.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog

The log-level and log-filters can now be configured using a file called simplelog.properties.

org.apache.commons.logging.simplelog.defaultlog=trace
org.apache.commons.logging.simplelog.log.org.pentaho.reporting=trace
org.apache.commons.logging.simplelog.log.com.opensymphony.oscache=warn
org.apache.commons.logging.simplelog.log.net.sf.ehcache=warn
org.apache.commons.logging.simplelog.showlogname=true

Configuring the logging system for Pentaho Reporting Classic 0.8.9 and older

Logging is controlled by the JFreeReport configuration. You can tweak the configuration by creating a 'jfreereport.properties' file, putting that into the root of your classpath (the 'default' package, or for instance WEB-INF/classes, if you're in a Servlet-Container).

The Log-Level is controlled by the property 'org.jfree.base.LogLevel', which can have the one of the following values: 'Debug', 'Info', 'Warn', 'Error'. The log-level should be at least at Warn so that you receive information on non-critical errors (like missing column names, etc.) which do not cause the reporting to fail, but may indicate an error in the report definition file.

# The minimum loglevel that is logged.
org.jfree.base.LogLevel=Info

In the very unlikely case that you dont want to log to System.out and want to use a different logging mechanism, you can switch the logger implementation using the configuration as well.

To use Log4J, use

org.jfree.base.LogTarget=org.jfree.logger.log4j.Log4JLogTarget

We also support Jakarta-Commons (org.jfree.logger.jcl.JakartaLogTarget) and JDK14 style logging (org.jfree.logger.java14.Java14LogTarget). These log-target implementation can be found in the JCommons-Logging package. (Downloadable at http://www.jfree.org/jcommon/download/ )
