OMapper
Automate your bean mappings seamlessly
...Supports mapping composed user class objects and array fields.
It is NOT an ORM Framework like Hibernate, but it facilitates object to object mapping between different design layers. So, say if hibernate or axis generates DTO's and you want to map them to your own beans , so at that point this framework can be used.
Please refer to the wiki for usage guidelines.
Key Benefits :
=> Smaller code foot-print
=> Faster development time
=> One time mapping creation
=> Easy to debug
=> Reduces the bugs due to missed mappings for large DTOs
