RE: Setting up XML configuration problems

[Mark Womack]

Title: Message

What error are you getting?  You might want to make the CONFIG_FILE a system property, that way you can change it at runtime.  My guess is that "config.xml" is not a valid path to the file.  You might need to fully qualify it like "file:c:/config.xml".

 

Also, just as a note, where you assign an int value to your LEVEL_* constants, instead of using a value like 0, 1,2, etc, you might want to use the built in int values from the defined Priority classes like this:

 

 public static final int DEBUG = Priority.DEBUG_INT;

That way you can use the value to map it to the defined Priority later, like this:

 

 public void log(int priority, Object message) {
  category.log(Priority.toPriority(priority), message);
 }

 

 It helps you avoid the switch statement.  But you seem to have info at a lower priority than debug, so using the defined priorities may not work too well for you...

Subject: Setting up XML configuration problems

Hello All,

 

I'm trying to set up my log4j configuration through an xml file.  My problem is that it's not connecting to my xml file.  Can anyone please provide a second and look at my code to see what my problem is below? 

 

I do appreciate any help!

 

Have a good one,

Steven

//  My Logger File 

public class Logger
{
 private static final String CONFIG_FILE = "config.xml";

 

 public static final int LEVEL_INFO  = 0;
 public static final int LEVEL_DEBUG  = 1;
 public static final int LEVEL_WARN  = 2;
 public static final int LEVEL_ERROR  = 3;
 public static final int LEVEL_FATAL  = 4;

 

 static void init( String configFile )
 {
  DOMConfigurator.configure( CONFIG_FILE );
 }

 

 public static void log( String classType, String message )
 {
  log( classType, LEVEL_DEBUG, message );
 }

 

 public static void log( String classType, int logLevel, String message )
 { 
  Category cat = Category.getInstance( classType );

 

  Category root = Category.getRoot( );
  int loggingLevel = root.getPriority( ).toInt( );

 

  switch(loggingLevel)
  {
  case LEVEL_INFO:
   cat.info( message );
   break;
  case LEVEL_DEBUG:
   cat.debug( message );
   break;
  case LEVEL_WARN:
   cat.warn( message );
   break;
  case LEVEL_ERROR:
   cat.error( message );
   break;
  case LEVEL_FATAL:
   cat.fatal( message );
   break;
  }
 }
}

 

My XML File:
