I think this decision is based only on the requirements of the project. Every of the above enumerated techs/frameworks have pros and cons (for example Gavin already posted here a list of cons post :-) ) which will help you decide upon the _best_ solution.

- EJB is not intended for persistence, but for components (which most of people seem to never understood). Some components need persistence, and so the EJB framework provide them a persistence service.

- Hibernate is for free/open source relational persistence

- JDO is for datastore-agnostic persistence (relational, but also mainframe, XML, etc.)

- Cayenne looks just like another Hibernate

In this forum I always assume/read when I see EJB, that there is in fact a reference to CMP.
 
It is sorta covered in the JavaRanch Style Guide.
