I'm somewhat a novice to J2EE. I don't know if DAO's can be used in a CMP based design. I'm planning on using DAO's for searches (such as flight search, seat availability search) etc and CMP entity beans for creating the itinerary.

Is it out of the norm to use CMP entity beans + DAOs?

You can use:

1. SLSB + DAO for Search operations

2. CMPs for persistence.

CMP + DAO is not a valid combination because code for CMP is generated by the EJB Container at the time of deployment so how would you plug in your DAO with CMP.

3. If you want you can use BMP + DAO for persistence.

Hope this helps
