Problem with logging

[Mike Semlitsch]

Hello Ranchers,

I have a basic problem with logging. My TestClass containing the main method does logging well. An object of my TestedClass which is created from the TestClass doesn't log anything, why?

package test.db;
 
public class TestClass {
   public static void main (String[] args) {
      Logger myLogger = Logger.getLogger("suncertify.db");
      myLogger.setLevel(Level.ALL);
      myLogger.severe("Info from Logger");  //This information is logged
 
      TestedClass testedClass = new TestedClass();
   }
}
 
------------------
 
package suncertify.db;
 
public class TestedClass {
   private transient Logger myLogger = Logger.getLogger("suncertify.db");
 
   public TestedClass() {
      myLogger.severe("Info from Logger");  //This information is NOT logged
   }
}

Thanks for any help.

Well, I can see both messages with code you posted.
You can try to flush logger at the end of main method.

Hi,

this topic has been asked before. you need to create a FileHandler . Example:

   
log = Logger.getLogger("package.className");
fh = new FileHandler("path/to/log");
log.addHandler(fh);

you can set formatter and other properties as well.

hope that helps.

Thanks for your answers.

You are right John! I've tested the classes I posted and it works. :-)

I've reduced the lines of code of the classes but I've made a mistake. In the TestedClass I use 'myLogger.finer("Finer-Info from Logger")' and this finer logging doesn't work, although I set the Log-Level to 'Level.ALL' in the TestClass.

By default, console output starts from.. INFO (I guess).

try

Logger.getLogger("").getHandlers()[0].setLevel(Level.ALL);

or edit $JRE_HOME/lib/logging.properties file in your JRE directory.

Thank you!

The default settings of the "logging.properties" were the reason. Using a FileHandler shows every log entry.
