let me try this...
u use VLHdlr normally for read only data, so preferably not for ejbs...okay ..but it doesnt prevent u...i mean for scalability reasons u may have ejbs.
regarding DAOs and VOs in class diagrams, i think it again boils down to the questions posed by Rethna and Raj in earlier threads - whether there shud be tech depndcy. in class diag...i feel in 1st pass u conc on identidfying domain objects and gradually u can have
J2EE dependent class provided the PROBLEM situation demands a J2EE soln (which in all likelihood would be the case... with

)
Can we have more opinions here???
