Hi,
I think that these 2 alternatives have their own set of merits and
de-merits. And your decision to choose one over another would typically
depend upon the following factors:
1. BUDGET / Time to GO Live:
If you are a little short on budget then I would highly recommend you to
re-use the existing SPs as development efforts for re-developing the entire
functionality presently residing in SPs will be greatly reduced. You can
probably wrap these SPs with JDBC constructs in very short time and built
an application in very short time.
2. Scalability / Security / Transaction Management / ETC:
If these issues concern you more then the obvious choice would be to
re-write the entire application in EJBs.
Regards,
Milind

Please respond to

SO to conclude...
If we have SPs already defined we shouldn't go for ENTITY BEANS

You will have to use wrapper/facade in SLSB/SFSB from which you can take
advanatage of the transactions and security. You can manage the transaction
in SPs also and propagate errors to the session bean methods.
Scalability issue will then shift to session beans.
