FAQ #7 - How to configure ADF diagnostics logging in standalone WLS using JDeveloper 11g R1


In FAQ #6 - How to fine tune ADF diagnostics logging in JDeveloper 11g R1 we’ve seen how to configure diagnostics logging for the integrated WLS in JDeveloper. Configuration of diagnostics logging for the standalone WLS can be done in a similar fashion. Let’s take a look.

For some basic information regarding ADF diagnostics logging refer to FAQ #6 - How to fine tune ADF diagnostics logging in JDeveloper 11g R1. We will repeat some of the introductory information here as it applies to the standalone WLS.

ADF diagnostics logging is controlled via the usage of the jbo.debugoutput parameter. Using this parameter with the console value, i.e. -Djbo.debugoutput=console, produces diagnostic logs directly in the JDeveloper Log console window when deploying and running an application on the integrated WLS in JDeveloper. When set to the ADFLogger value, diagnostics are routed through the standard J2SE Logging API and are controlled through the logging.xml configuration file. For the standalone WLS this file can be found in the %MIDDLEWARE_HOME%\user_projects\domains\%DOMAIN_NAME%\config\fmwconfig\servers\%SERVER_NAME% for the Windows operating systems.

%MIDDLEWARE_HOME% is the installation directory of the standalone WLS, %DOMAIN_NAME% and %SERVER_NAME% are the WLS domain and server that we are configuring. For information on how to setup the standalone WLS, take a look at FAQ #1 – How to configue the standalone WebLogic server for deploying ADF applications from JDeveloper 11g R1 (

Let's locate the logging.xml file in the above directory and drag and drop it on JDeveloper.

JDeveloper will open the file and display it in the Overview tab.

In order to produce detailed diagnostic logs for the ADF BC oracle.jbo classes, we need to set the log Level to at least FINE. Let's set it to the most detailed level FINEST - TRACE:32 if using ODL Log Levels - for the oracle.jbo logger. Also let's ensure that the odl-handler log handler is configured to generate diagnostics for all log levels. To verify, select the odl-handler in the structure window and ensure that the level attribute is set to ALL.

Lastly we need to specify the -Djbo.debugoutput=adflogger -Djbo.adflogger.level=FINEST parameters when starting the standalone WLS, so let's open the setDomainEnv.cmd domain environment settings script in the %MIDDLEWARE_HOME%\user_projects\domains\%DOMAIN_NAME%\bin directory and add the following line:

set JAVA_OPTIONS=%JAVA_OPTIONS% -Djbo.debugoutput=adflogger -Djbo.adflogger.level=FINEST

That's all there is to it! Now let's start the standalone WLS, deploy and run our application. Take a look at FAQ #3 - How to deploy an ADF application on a standalone WebLogic server directly from JDeveloper for information on how to deploy an application onto WLS.

You should see those familiar ADF BC oracle.jbo diagnostic logs come flying in the WLS log window!


ADF Diagnostics Logging for the standalone WLS is done through the logging.xml file in a similar fashion as for the integrated WLS. It is a powerful feature that allows us to fine tune the log generation of our application and much more.

Until the next time, keep on JDeveloping!


  1. how could i specify the Custom formatter and handler

    I tried in one of the way

    formatter='java.util.logging.SimpleFormatter' here even the file is not creating it.

    In a programmatic way i was able to do it, here i given the example

    public static void log(final Level level, final Class obj, final String method, final String message, final Object... params)
    FileHandler cfh;
    cfh = new FileHandler("E:\\11.3\\Oracle\\jdev\\system11.\\DefaultDomain\\servers\\DefaultServer\\logs\\mylog.txt");
    cfh.setFormatter(new java.util.logging.SimpleFormatter());

    ADFLogger aDFLogger = ADFLogger.createADFLogger(obj);
    aDFLogger.logp(level, obj.getName(), method, message);
    aDFLogger.entering(obj.getClass().getName(), method, message);
    catch (IOException e)
