how to print stacktrace in log using logging

Former Member — Thu, 28 May 2009 05:08:41 GMT

Hi All ,

I am using logging in my webdynpro application

I hv written following java class for logging

***************************************java class Starts *******************************

public class ReferenceApplicationEJBLogger {

private static final Location LOCATION = Location.getLocation("com.apl");

private static final Category CATEGORY = Category.getCategory(Category.APPLICATIONS, "Reference Application");

static{

LOCATION.setMinimumSeverity(CATEGORY, Severity.INFO);

LOCATION.setMaximumSeverity(CATEGORY, Severity.ALL);

CATEGORY.addLog(new FileLog("./log/application/hrhelpdesk/edmProject.%g.trc"));

}

public static void logException (Exception eMessage){

logThrowable(eMessage);

eMessage.printStackTrace();

}

public static void logThrowable (Throwable eMessage){

CATEGORY.logThrowableT(Severity.WARNING, LOCATION, eMessage.getLocalizedMessage(), eMessage);

}

public static void logWarning (String logWarning, Exception eMessage) {

CATEGORY.warningT(LOCATION, logWarning, new Object[]{eMessage});

}

public static void logInfo (String logString){

CATEGORY.infoT(LOCATION, logString);

}

public static void logWarn (String logString){

CATEGORY.warningT(LOCATION, logString);

}

***********************************Java class ends here **********************************

and inside my webdynpro applicaiton i have written following code in side catch block

ReferenceApplicationEJBLogger.logInfo("Error occured in application" );

log is getting written in to defined locaiton ./log/application/hrhelpdesk/edmProject.%g.trc

but i also want to print e.printStackTrce() in above mentioned location along with message "Error occured in application".

How to go about it ? Thnx in advance

Regards

Let me understand first, are you looking at printing the complete exception log?

catch (Exception e) {

StringWriter sw = new StringWriter();

PrintWriter pw = new PrintWriter(sw);

e.printStackTrace(pw);

System.out.println(sw.toString().toUpperCase());

}

Tested, it works.

ya it worked for me also. but still it is writing data to location created for my application and also in ./log folder in trc file. I don't want to put it to ./log in trc file. I want to write only in location created for my application

The standard log files content is controlled by server. For that you will have to setup in Visual admin log service. I dont remember the name of the service, but there you can set the logging level to info/error etc...
