Getting the location of class file

[Kashif Iqbal Khan]

Is there anyway I could find the path of the class file that is being executed.

[David O'Meara]

In code, turn the fully qualified class name into a file path, then use getResource() from the ClassLoader and print out the URL it returns. If you keep it as a URL, it will even show the location in JARs.
eg to find com.javaranch.davo.MyClass

import com.javaranch.davo.MyClass;
String filePath = "/com/javaranch/davo/MyClass.class";
URL location = MyClass.class.getResource( filePath );
System.out.println("Location: "+location);

That may need debugging, I wrote it off the top of my head.

If you're just trying to figure out the working directory of some Java application, then the "user.dir" System property might do the trick.

public class Foo
{
  public static void main (String [] args) throws Exception
  {
    System.out.println(System.getProperty("user.dir"));
  }
}
