How to convert the class in the one package to same class in the other pack

Question

How to convert the class in the one package to same class in the other package
example:
BeanDTO.java
package cho3.hello.bean;
public class BeanDTO {
private String name;
private int age;
* @return
public int getAge() {
     return age;
* @return
public String getName() {
     return name;
* @param i
public void setAge(int i) {
     age = i;
* @param string
public void setName(String string) {
     name = string;
BeanDTO.java in other package
package ch03.hello;
public class BeanDTO {
private String name;
private int age;
* @return
public int getAge() {
     return age;
* @return
public String getName() {
     return name;
* @param i
public void setAge(int i) {
     age = i;
* @param string
public void setName(String string) {
     name = string;
My converter lass lokks like
public class BeanUtilTest {
     public static void main(String[] args) {
          try
               ch03.hello.BeanDTO bean=new ch03.hello.BeanDTO();
          bean.setAge(10);
          bean.setName("mahesh");
          cho3.hello.bean.BeanDTO beanDto=new cho3.hello.bean.BeanDTO();
          ClassConverter classconv=new ClassConverter();
          //classconv.
          System.out.println("hi "+beanDto.getClass().toString());
          System.out.println("hi helli "+bean.toString()+" "+bean.getAge()+" "+bean.getName()+" "+bean.getClass());
          Object b=classconv.convert(beanDto.getClass(),(Object)bean);
          System.out.println(b.toString());
          beanDto= (cho3.hello.bean.BeanDTO)b;
          System.out.println(" "+beanDto.getAge()+" "+beanDto.getName() );
          }catch(Exception e)
               e.printStackTrace();
But its giving class cast exception. Please help on this..

Do you mean "two different layers" as in separate JVMs or "two different layers" as in functional areas running within the same JVM.
In either case, if the first class is actually semantically and functionally the same as the second (and they are always intended to be the same) then import and and use the first class in place of the second. That's beyond any question of how to get the data of the first into the second if and when you need to.
Once you make the breakthrough and use one class instead of two I'd guess that almost solves your problem. But if you want to describe your architecture a little that would help others pin down want you're trying to do.
