Custom loading class

[pb2000]

Hello,
I have problem with ObjectInputStream.ReadObject() method.
Code below

FileClassLoader externalLoader = new FileClassLoader(currentTaskDir);
Class c = externalLoader.loadClass(className);
Method mlist[] = c.getDeclaredMethods();
Object[] objectsPassed = null;
objectsPassed = (Object[])ois.readObject();
Object examinedObj = objectsPassed[0];
String methodName = (String)objectsPassed[1];
 

in main directory I have directory "currentTaskDir" with class "ClassName".class.
Class c is loaded with custom loader from currentTaskDir directory.
Nevertheless, reading ObjectInputStream takes into account only classes from classpath. I do not want to add currentTaskDir to classpath, because of further reloading class.
objectPassed is group of String and ClassName (c). How can I cast ois.ReadObject() to String and c?

Thank You for answers. I will be grateful for them.
Paul
