How to copy properties from a bean to another bean in different class?

Use BeanUtils:

import org.apache.commons.beanutils.BeanUtils;

UserBean newObject = new UserBean(); 
BeanUtils.copyProperties(newObject, oldObject);

Check out the Dozer Framework - its an object to object mapping framework. The idea is that:

• Usually it will map by convention.
• You can override this convention with a mapping file.

. . therefore mapping files are as compact as possible. Its useful for many cases, such as mapping a use-case specify service payload on to the reusable core model objects.

When delivering the SpringSource training courses we used to point out this framework very often.

Edit:

These days try MapStruct.
