Enabling Logging for Applications

There are two main steps in enabling logging for your application:

1. Identify a source code area (for example, a class Node ) and represent it with a Location object:

   Location loc = Location.getLocation("<package>.Node");

2. Input a trace message with specified severity:

   loc.entering(methodname);

   loc.debugT(methodname, message);

   loc.fatalT(methodname, message);

A very basic sample code shows these two steps:

package com.sap.fooPackage;
import com.sap.tc.logging.*;
public class Node {
   
private static final Location loc =
      Location.getLocation("com.sap.fooPackage.Node");
   
public void announce(Object o) {
      String method = "announce(java.lang.Object)";
      loc.entering(method);
      try {
         // do something...
         loc.debugT(method, "Connecting to …");
      } catch (Exception e) {
         loc.fatalT(
            method,
            "Error processing object {0}",
            new Object[] { o });
      }
      loc.exiting();
   }
}
         

The output is redirected to a ConsoleLog (terminal).

The output, formatted with TraceFormatter (default formatter for ConsoleLog ), looks like this:
