Hi Ram,
thanks a lot for your long answer. I imagine I can obtain the same
result launching client & server with different -Dlog4j.configuration
option (pointing to their own log4j file) . Right ?
Thanks alot
Francesco
Hi Francesco,
Since you are having single property file which appends
to JMSAppender both your client and MDB consumes the same file so it
does happens infinite loop...load prop file which appends to JMSAppender
from client and load prop file which write to a file in MDB.
E.g
In your client pgm load the following
String resource = "/client_config.xml";
URL configFileResource Logger.class.getResource(resource);
System.out.println("configFileResource
:"+configFileResource);
DOMConfigurator.configureAndWatch(configFileResource.getFile(),10);
In your MDB load the following
String resource = "/server_config.xml";
URL configFileResource Logger.class.getResource(resource);
System.out.println("configFileResource
:"+configFileResource);
DOMConfigurator.configureAndWatch(configFileResource.getFile(),10);
Where client_config.xml contains the following prop which call
JMSAppender
client_config.xml
<?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="JMS"
class="org.apache.log4j.net.JMSAppender  ">
<param name ="TopicBindingName" value="name"/>
<param name ="InitialContextFactoryName"
value="weblogic.jndi.WLInitialContextFactory"/>
<param name ="TopicConnectionFactoryBindingName"
value="weblogic.examples.jms.TopicConnectionFactory"/>
<param name ="ProviderURL" value="url">
</appender>
<root>
<appender-ref ref="JMS" />
</root>
</log4j:configuration>
Where server_config.xml contains the following prop which write to a
file
server_config.xml
<?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="FILE" class="org.apache.log4j.RollingFileAppender ">
<param name="File" value="C:\\xyz.log"/>
<param name="MaxFileSize" value="3KB"/>
<param name="MaxBackupIndex" value="2"/>
<layout class="org.apache.log4j.PatternLayout ">
<param name="ConversionPattern" value="%d [%t]
%-5p %c - %m%n"/>
</layout>
</appender>
<root>
<level value ="debug"/>
<appender-ref ref="FILE" />
</root>
</log4j:configuration>
I hope this help

Subject: Using a JMS Appenger together with a File Appender
Hi all,
I'm trying to write an app where all application logs are sent to a JMS
queue and in turn a MDB consumes the message and writes the
logs in a DailyFileAppender.
This is the core of my log4j.xml, which doesn't work because log message
sent by the
MDB are re-sent again in the JMS queue in an infinite loop :-( ) How do
I write it correctly ?
Thanks alot
Francesco

<category name="ejb.MdbLoggerEJB">
<priority value="DEBUG" />
<appender-ref ref="FILE"/>
</category>
<root>
<level value="DEBUG"/>
<appender-ref ref="JMS"/>
