hi all,
i just tried extending java.lang.ClassLoader.
Then i tried loading the same class (TestLoader) using my loader as mentioned in javageeks.com
But the class loader that loaded TestLoader is getting used again.
TestLoader's findClass is'nt getting called at all!
I have the code here.
findClass just opens the .class file and reads in the bytes.
can comeone suggest something as to why the second tiem around my sutom class laoder did'nt get used.
regards
karthik.
import java.io.*;
public class TestLoader extends ClassLoader{
protected TestLoader(){
super(TestLoader.class.getClassLoader());
System.out.println("TestLoader");
}
public Class findClass(
String name) throws ClassNotFoundException{
String file = "d:\\java\\ClassLoaders" + name + ".class";
byte[] classBytes = null;
Class retClass = null;
try{
FileInputStream fis = new FileInputStream(file);
classBytes = new byte[fis.available()];
fis.read(classBytes);
retClass= defineClass(name,classBytes,0,classBytes.length); }catch(Exception e){
e.printStackTrace();
throw new ClassNotFoundException("class not found");
}
return retClass;
}
public static void main(String[] args)throws Exception{
TestLoader loader = new TestLoader();
System.out.println(loader.getClass().getClassLoader());
TestLoader l = null;
Class c=loader.loadClass("TestLoader");
l = (TestLoader)c.newInstance();
System.out.println(l.getClass().getClassLoader());
}
}
