Thanks a lot..but here we are having hundreads of classes..
in this case any solution is there
This might help you getting started:
helpers/FooBar.java
=====
package helpers;
public class FooBar {
public static void main(String[] args) {
System.out.println("Hello World");
System.out.println("Hello World");
org.slf4j.LoggerFactory.getLogger(Me.callerClass()).info("Hello
World");
org.slf4j.LoggerFactory.getLogger(Me.callerClass()).info("Hello
World");
}
}
=====
helpers/Me.java
====
package helpers;
public class Me {
public static String callerClass() {
StackTraceElement[] stackTrace =
Thread.currentThread().getStackTrace();
int level = 0;
while
(stackTrace[level].getClassName().equals(Me.class.getCanonicalName()) ==
false) {
level = level + 1;
}
// level is now *HERE*
StackTraceElement element = stackTrace[level + 1];
return element.getClassName();
}
}
====
When FooBar is run, it generates this output:
===
Hello World
Hello World
0 INFO helpers.FooBar Hello World
0 INFO helpers.FooBar Hello World
===
Hence you should be able to globally replace instances of
"System.out.println" / System.err.println with
"org.slf4j.LoggerFactory.getLogger(helpers.Me.callerClass()).info" in
your text files and have something working.
This requires Java 5 and is slower than actually creating a static
logger instance but allows you to postpone the actual nitty gritty stuff
for later.
