Is it possible to pass Java data objects to  stored procedures?

I have a stored procedure framework that accepts in parameters and returns ouput..but now ..I have a huge data structure of 150 fields to be passed in as input parameters which makes it impossible to type all that in the SP as input.. How do I do this?

Quick answer...you can't. You will probably need to create a single value (like a huge comma separated string) that you would pass into the stored procedure.
Then, in the stored procedure, you would parse it and split it into little pieces.

You can also try having 150 parameters to the stored proc, however that might be a problem with some databases that will limit the number of parameters to a stored proc.

Even if it is possible, its not advisable either because then you limit yourself to only those databases which support Java objects. You won't be able to port or migrate to other databases. I would say keep the application layer generic of the database and let the DAO layer communicate with the database using stored procedures by passing data in the form of whatever complies with plain SQL specifications

You can pass Java objects to stored procedures but that would heavily tie your application to the database and I would say that is bad architecture:
