vi /opt/oracle/fmw11_1_1_5/wlserver_10.3/common/bin/commEnv.sh
add this to WEBLOGIC_CLASSPATH:
${CLASSPATHSEP}/opt/oracle/fmw11_1_1_5/wlserver_10.3/server/lib/slf4j-api-1.7.5.jar${CLASSPATHSEP}/opt/oracle/fmw11_1_1_5/wlserver_10.3/server/lib/logback-core-1.0.13.jar${CLASSPATHSEP}/opt/oracle/fmw11_1_1_5/wlserver_10.3/server/lib/logback-classic-1.0.13.jar
and copy the JARs:
cd /opt/oracle/fmw11_1_1_5/wlserver_10.3/server/lib/
this only if you have Nexus, otherwise.... copy them manually:
wget http://nexus.nespresso.com/service/local/repositories/adobe-ext/content/ch/qos/logback/logback-core/1.0.13/logback-core-1.0.13.jar

I provide a custom XPath to log :
package com.acme.osb.logging;
import org.apache.xmlbeans.XmlObject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
* Used by OSB to report an Event
*
* @author NNVernetPI
*
*/
public class MessageTrackerSLF4J {
public static String logMessage(String technicalMessageid,
String businessId, String eventType, String interfaceName,
XmlObject payload) {
Logger projectLogger = LoggerFactory.getLogger(interfaceName);
StringBuilder sb = new StringBuilder();
if (projectLogger.isDebugEnabled()) {
sb.append(" ::InterfaceName:: ").append(interfaceName)
.append(" ::Payload:: ").append(payload.xmlText())
.append(" ::BusinessID:: ").append(businessId);
} else {
sb.append(" ::TechnicalMessageID:: ").append(technicalMessageid)
.append(" ::BusinessID:: ").append(businessId)
.append(" ::InterfaceName:: ").append(interfaceName)
.append(" ::EventType:: ").append(eventType)
.append(" ::ServerName:: ")
.append(System.getProperty("weblogic.Name"));
}
projectLogger.info(sb.toString());
String logmessage = "Info Message Logged for:: " + interfaceName;
return logmessage;
}
public static String errorLogger(String technicalMessageid,
String businessId, String interfaceName, XmlObject payload,
String priority, XmlObject fault) {
Logger projectLogger = LoggerFactory.getLogger(interfaceName);
StringBuilder sb = new StringBuilder();
sb.append("::TechnicalMessageID:: ").append(technicalMessageid)
.append(" ::InterfaceName:: ").append(interfaceName)
.append(" ::BusinessID:: ").append(businessId)
.append(" ::Payload:: ").append(payload.xmlText())
.append(" ::Priority:: ").append(priority)
.append(" ::FaultDescription:: ").append(fault.xmlText())
.append(" ::ServerName:: ")
.append(System.getProperty("weblogic.Name"));
projectLogger.error(sb.toString());
String responseMessage = "Error Message Logged for:: " + interfaceName;
return responseMessage;
}
}
which I expose as XPath this way:
<xpf:function>
<xpf:name>LOG_SLF_errorLogger</xpf:name>
<xpf:comment>logs an error</xpf:comment>
<xpf:namespaceURI>http://www.acme.com/acme2/xquery/xquery-functions</xpf:namespaceURI>
<xpf:className>com.acme.osb.logging.MessageTrackerSLF4J</xpf:className>
<xpf:method>java.lang.String errorLogger(java.lang.String, java.lang.String, java.lang.String, org.apache.xmlbeans.XmlObject, java.lang.String, org.apache.xmlbeans.XmlObject)</xpf:method>
<xpf:isDeterministic>false</xpf:isDeterministic>
<xpf:scope>Pipeline</xpf:scope>
<xpf:scope>SplitJoin</xpf:scope>
</xpf:function>
<xpf:function>
<xpf:name>LOG_SLF_messageTracker</xpf:name>

Since I have activated the jmxConfigurator, I can reload the logback.xml configuration file by connecting with JMX:
jconsole -J-Djava.class.path=C:\Oracle\MIDDLE~1\JDK160~1\lib\jconsole.jar;C:\Oracle\MIDDLE~1\JDK160~1\lib\tools.jar;C:\Oracle\Middleware\wlserver_10.3\server\lib\wlfullclient.jar -J-Djmx.remote.protocol.provider.pkgs=weblogic.management.remote -debug
and connect as:
service:jmx:iiop://myserver.acme.com:8001/jndi/weblogic.management.mbeanservers.runtime
The advantage is that I can also set programmatically the logger level for each logger, via JMX.
see here the doc, the first argument is the loggerName, the second is the level
A note: reloadByFileName() requires the FULL PATH : /opt/oracle/domains/osbpl1do/config/osb/logback.xml
