I tried to follow the orientation below to control eclipselink log using commonslog/log4j configuration:

http://wiki.eclipse.org/EclipseLink/Foundation/Logging (Using Log4J)

I was not able to turn on and off eclipselink messages changing log4.properties or log4.xml file.
The only way to do this was changing persistence.xml (eclipselink.logging.level) to FINE or SEVERE.

My log4.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd" >
<log4j:configuration>
	<appender name="stdout" class="org.apache.log4j.ConsoleAppender">
		<layout class="org.apache.log4j.PatternLayout">
			<param name="ConversionPattern" value="%d{ABSOLUTE} %5p %c{1}:%L - %m%n" />

		</layout>
	</appender>
	<logger name="org.eclipse.persistence">
		<level value="info" />
	</logger>
	<root>
		<priority value="error"></priority>
		<appender-ref ref="stdout" />
	</root>
</log4j:configuration>

My persistence.xml properties:


			<property name="eclipselink.logging.logger" value="org.eclipse.persistence.logging.CommonsLoggingSessionLog"/>
			<property name="eclipselink.logging.level" value="severe" />

You might try debugging the code you are using in the shouldLog() method. It seems it is somehow not returning the value from the log4j logging correctly.

You are right. The level is comming from persistence.xml and not from log4j.xml.
I put the following line in the beggining of should log method

debug("CommonsLoggingSessionLog.shouldLog : IN : category : " + category + " : " + level + " >>=" + getLogWrapper(category).getLevel() + " " + getLevelString(level) + ">>=" + getLevelString(getLogWrapper(category).getLevel())) ;

And the result is

CommonsLoggingSessionLog.shouldLog : IN : category : sql : 3 >>=7 FINE>>=[b]SEVERE[/b]

When I change to level in persistence.xml from SEVERE to FINE, the result is:

CommonsLoggingSessionLog.shouldLog : IN : category : sql : 3 >>=3 FINE>>=[b]FINE[/b]

And the log message of sql is shown using the format specified in log4j.xml. So, the format is obtained correctly, but the level not.

I'm using the same code of CommonsLoggingSessionLog published in
http://wiki.eclipse.org/EclipseLink/Foundation/Logging

What can I do to change this behaviour?

Thanks. Mauro.

Unfortunately I had to change the implementation of CommonsLoggingSessionLog to make it work the way I expected.

In the method addLogger I changed the line:

this.CATEGORY_LOGGERS.put(loggerCategory, new LogWrapper(this, loggerCategory, LogFactory.getLog(loggerNameSpace)));

By this line:

this.CATEGORY_LOGGERS.put(loggerCategory, new LogWrapper(this, loggerCategory, LogFactory.getLog("org.eclipse.persistence" + "." + loggerCategory)));

And in the method shouldLog I added the 3 lines below

default:
                final LogWrapper lw = getLogWrapper(category);
                if (lw.getLog().isDebugEnabled()) { // added
                  return true;  // added 
                } // added

It is not the best solution, but it is working according to my requirementes.

I would appreciate using the original code if I could identify where is the problem.

Thanks.
