Logger making cumulative entries

Are u using any static variables or trying to append the same entry to StringBuffer? can you post the code?

Java Snippet:

...
public class AEF4690AccessBean{
...
     public AEF4690AccessBean() {

          String thisClassname = this.getClass().getName();
          Logger log = ((JSpaLogger)JSpaServletListener.sc.getAttribute("SystemLog")).createLogger(thisClassname );
          log.entering(thisClassname,"AEF4690AccessBean()");
...
}

------------------------------------

log after 1st call:

Sep 23, 2005 1:00:15 PM com.softechnics.AEF4690AccessBean AEF4690AccessBean()
FINER: ENTRY

log after 2nd call:

Sep 23, 2005 1:00:15 PM com.softechnics.AEF4690AccessBean AEF4690AccessBean()
FINER: ENTRY
....
Sep 23, 2005 1:00:15 PM com.softechnics.AEF4690AccessBean AEF4690AccessBean()
FINER: ENTRY
Sep 23, 2005 1:00:15 PM com.softechnics.AEF4690AccessBean AEF4690AccessBean()
FINER: ENTRY


log after 3rd call:

Sep 23, 2005 1:00:15 PM com.softechnics.AEF4690AccessBean AEF4690AccessBean()
FINER: ENTRY
....
Sep 23, 2005 1:00:15 PM com.softechnics.AEF4690AccessBean AEF4690AccessBean()
FINER: ENTRY
Sep 23, 2005 1:00:15 PM com.softechnics.AEF4690AccessBean AEF4690AccessBean()
FINER: ENTRY
...
Sep 23, 2005 1:00:15 PM com.softechnics.AEF4690AccessBean AEF4690AccessBean()
FINER: ENTRY
Sep 23, 2005 1:00:15 PM com.softechnics.AEF4690AccessBean AEF4690AccessBean()
FINER: ENTRY
Sep 23, 2005 1:00:15 PM com.softechnics.AEF4690AccessBean AEF4690AccessBean()
FINER: ENTRY

etc....

Let me modify the above snippet to the exact code (in trying to keep it simple, it's possible I ommitted something important here):

...
public class AEF4690AccessBean{
...
     Logger log = null;
...
     public AEF4690AccessBean() {

          String thisClassname = this.getClass().getName();
          if (log == null) {
               log = ((JSpaLogger)JSpaServletListener.sc.getAttribute("SystemLog")).createLogger(thisClassname );
          }
          log.entering(thisClassname,"AEF4690AccessBean()");
...
}

Very odd. It's as if the data is being kept in a buffer, written to the log file, but then not being cleared from the buffer...

I'm unfamiliar with this "Logger" class you're using -- is it custom? Is there some kind of flush() method with it?

Also, by redefining the log instance each time (ie., by removing the "if ( log == null )" line), then does this fix the problem? (I know this probably leaves some efficiency issues that would need to be resolved, but it would probably give us a better idea of what's causing the current problem..

This is the Logger class that comes with the J2SE 1.4 API. Nothing custom.

I'll try instantiating a new Logger with each call. Same thought I just had - which is why I modified the snippet.

Your creating a new logger for *every* instance of your class, you only need one

So each instance of AEF4690AccessBean has its own logger.. how are you invoking the method that is being traced?

objects.. you and I are on the same page.. but it is strange that the loggers of a class all know about each other..

I am curious about the invocation class though.. are you instantiating a new AEF4690AccessBean each time and so after three calls you have three beans?

I was, but thanks to you and Objects I've plugged that hole.

Thanks.

glad to see you have it worked out.. sad to see I didn't get any points.. LOL!

One final question, if I may:

The Logger javadoc recommends a logger for each class, which I created. I assumed this meant a log file for each logger - not what I'd really want, but I was learning. As it turns out, there is only one log file. Are all loggers (for each class) sharing the one log file?

Every Class has this:

          if (log == null) {
               log = ((JSpaLogger)JSpaServletListener.sc.getAttribute("SystemLog")).createLogger(<Classname>.class.getName());
          }

Then each method within the Class has this:

          log.entering(<Classname>.class.getName(),"<thisMethodName>()");
