Find from which jar a class was loaded

In order to find at runtime where from file system a class was loaded, following command would be useful:

System.out.println(<myjavaclassname>
               .class.getProtectionDomain()
                  .getCodeSource().getLocation());

Output will be something like this:
file:/C:/TestWorkSpace/lib/MyLibrary.jar

It can be helpful while debugging some class loading problems.
