将Java对象/类从一个类加载器复制到另一个类加载器(Copy java object/class from one classloader to another classloader)

 嗨有没有办法从一个类加载器（例如'made'类Point）复制一个类加载上下文（atrributes等）到另一个类加载器？ 
 
 清楚，例如：我有一个对象指向CL 1.现在运行在另一个CL2上，我想在CL 3中创建这个对象。 
 
 一些obj： 
 
class Point {
int x;
int y;
public Point() {}
//getters and setters
 
 风景： 
 
... 
class CL2 {

// Running on CL 2
...
// Point obj from CL 1
Object point = gotFromCL1();

// Want to create the object on Cl2
Object pointCL2 = point.conversion();
 
 但是我不能使用sun.reflection（不可用），并且序列化不起作用，因为CL2自动使用CL 1“重建”对象。 
 
 我所做的一个解决方案是做一个“100％”的java反射rconstruct，基本上从CL2获取对象的字段并设置新的obj。 
 
 PS：它需要在Java 1.4.2上运行：'（ 

Hi is there a way to copy one class loaded context (atrributes etc) from one classloader (for instance a 'made' class Point) to another classloader?
 
Making clear, Example: I have an object Point on CL 1. Now running on another CL2, I want to creat this object in CL 3.
 
Some obj:
 
class Point {
int x;
int y;
public Point() {}
//getters and setters
 
Scenery:
 
... 
class CL2 {

// Running on CL 2
...
// Point obj from CL 1
Object point = gotFromCL1();

// Want to create the object on Cl2
Object pointCL2 = point.conversion();
 
But I can't use sun.reflection (not available) and serialization doesn't work since CL2 automatically "reconstruct" the object with CL 1. 
 
One solution that I tought was do an "100%" java reflection rconstruct, basically getting the fields of object from CL2 and setting up on the new obj.
 
PS: It needs to run on Java 1.4.2 :'(
