Here’s a tip to demonstrate how to know from where a Java Class was loaded in Java.

Java Example

Here’s an example to load a Java class called “Address “, package in “com.mkyong.io“, and print out the location from where this class was loaded.

import java.net.URL;
import java.security.CodeSource;
import java.security.ProtectionDomain;
 
public class App{
 
	public static void main(String[] args) {
 
	try{
 
		Class cls = Class.forName("com.mkyong.io.Address");		
		ProtectionDomain pd = cls.getProtectionDomain(); 
		CodeSource cs = pd.getCodeSource(); 
		URL url = cs.getLocation();
		System.out.println(url.getFile());
 
	}catch(Exception ex){
		ex.printStackTrace();
	}
 }
}

Output

/E:/workspace/HibernateExample/target/classes/

The Java class “Address” is located at “E:/workspace/HibernateExample/target/classes/com/mkyong/io/Address.class”
