Log Configuration for a Web Dynpro application

[Former Member]

Hallo,

I have tried to configure the logging in the wd project but something is wrong couse no file is written.

In the wdDoInit of my view x.y.z.view.GetRunnableProcessView I have put the following:

//directs log messages to a file

logger.addLog(new FileLog(wdContext.currentPropertyElement().getLogFilename()));

//set severity

logger.setEffectiveSeverity(Severity.ALL);

logger.entering("entering string");

logger.exiting("exiting string");

My log-configuration.xml is the following:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE log-configuration SYSTEM "log-configuration.dtd">

<log-configuration>

<log-controllers>

<log-controller

effective-severity="PATH"

name="x.y.z.view.GetRunnableProcessView"/>

</log-controllers>

</log-configuration>

In the visualAdmin >> Log Configuration Properties, the ForceSingleTraceFile is set to "NO".

The problem is that in the Log Configurator service in Visual admin I don't find my location tree and no log file is written.

Could somebody help me please?

Thanks,

regards

Hallo,

the best way is to implement log4j. That is easy to implement and to configure.

Here is the link for download. http://logging.apache.org/log4j/1.2/download.html

Than you have to reference the log4j???.jar in your Application.

Next is to configure your properties (xml) file.

1. the root-logger level ERROR

log4j.rootLogger=ERROR, WD

1. now we attemp an appender to the conosole

log4j.appender.WD=org.apache.log4j.ConsoleAppender

#For this appende generade a Layout

log4j.appender.WD.layout=org.apache.log4j.PatternLayout

1. date shown in ISO-Format ISO-8601

log4j.appender.WD.layout.ConversionPattern=%d [%t] %-5p %c - %m%n

#for all class an packages "com.company.tests" the level DEBUG

log4j.logger.com.company.tests =DEBUG

********************

Implement this in your Application

PropertyConfigurator.configureAndWatch( "log4j.properties", 60*1000 );

put this in the begin others and end others

private static final Logger log = Logger.getLogger(<Your Company ControllerName>.class);

now you are able to log with

log.debug("Tests");

in your application

Take a look at this [doc|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/0c6ada90-0201-0010-4397-b6dcb6e661a2] for setting up and using sap logger.

Once configured, just use the already defined logger in WDP

eg: logger.errorT()
