They can live in any, and multiple, layers.

Lets see we have

Client Tier ---> Presentation Layer(JSP & Servlet, JSF,SPring Controller,Struts ) --> Business Layer(EJ beans) ---> Integration Layer (JDBC,JCA,JMS,Hibernate) --> ESI Layer

so if we have Spring POJO, JSF POJO,Hibernate POJO and Simple Java Beans use in JSP for MVC..

then tell me please where all these POJO will fit into the above layers...

Thanks in adance
