Java Database Connectivity (JDBC)

I need to pass in a complex object (object with nested array of objects) into a oracle stored procedure.

We are using JDBC 9.2.0.1 drivers...

Note i am able to retrieve a complex object successfully using an oracle struct however i am not able to pass in the struct.

I do not want to use JPublisher as we are not using SQLJ.
I have looked through the documentation on using default structs and am getting an error when i try and create the struct...

I have created an array of objects with a sub array
and i create a struct descriptor however when i create the actual oracle struct

like

oracle.sql.Struct = new oracle.sql.Struct( structDesc,conn,complexobject)

I get a "java.sql.SQLException: Internal Error: Unable to resolve name"

Do i have to create STRUCTS for the nested object first ?

And then nest that STRUCT within the PARENT STRUCT to pass in complex objects ???

Any help would be much appreciated...
