Calling Stored Procedure w/JPublisher generated classes

Question

Hi,
We are trying to pass Oracle nested tables as input/output parameters to several of our stored procedures to support bulk binding operations in the database from our applications. We have some database defined types and stored procedures that use these as input/output parameters which have been tested and working at the database level. I managed to get JPublisher to create these classes and compile fine, but I am not sure exactly how to register these classes as parameters with the stored procedure Java call. Any assistance is appreciated.
Here is a sample of the db types/procedures:
TYPE USER_APP_TYPE IS OBJECT
    User_ID             VARCHAR2(50), -- input fields
    App_ID              VARCHAR2(50),
    App_Type            VARCHAR2(50),
    App_Obj_ID          VARCHAR2(50),
    Status              VARCHAR2(30),   -- output fields
    Desc_String         VARCHAR2(255),
    Comments            VARCHAR2(255)
TYPE USER_APP_LIST IS TABLE OF USER_APP_TYPE;
CREATE OR REPLACE
PACKAGE BODY PKG_MOD_BULK
AS
    PROCEDURE LOOKUPAPPBYUSER_BULK(
        p_InOutRS   IN OUT  USER_APP_LIST)
    IS
        BEGIN
        ... do work - fill in output fields ...
        END LOOKUPAPPBYUSER_BULK;
END PKG_MOD_BULK;So using JPublisher 3 classes were generated with constructors and getter/setter methods:
UserAppType.java
UserAppTypeRef.java
UserAppList.java
My consumer POC code looks like this:
public class BulkBindingDemo
    @SuppressWarnings("CallToThreadDumpStack")
    public static void main(String[] args) 
        Connection conn = null;
        try
            String UserName = "user";
            String Password = "pass";
            // Load JDBC driver
            Class.forName("oracle.jdbc.OracleDriver");
            conn = DriverManager.getConnection("jdbc:oracle:thin:@mydatabse.com:1521:mysid", UserName, Password);           
            // Create instances of custom database UDT classes.
            UserAppList myAppList = new UserAppLicList();
            UserAppType[] myAppArr = new UserAppType[2];
            // Populate UDTs          
            myAppArr[0] = new UserAppType("bob" ,"acct","fiscal","1FG452ABC",null,null,null,null,null,null,null);
            myAppArr[1] = new UserAppType("joe","hr","benefits","89JTYG671",null,null,null,null,null,null,null);
            myAppList.setArray(myAppArr);                                               
            // Not sure how to set parameter as input/output.
            CallableStatement cs = conn.prepareCall("BEGIN MY_SCHEMA.PKG_MOD_BULK.LOOKUPAPPBYUSER_BULK(?); END;");
            cs.setObject("p_InOutRs", myAppLicList);
            cs.execute();
            ResultSet rs = cs.getResultSet();
            // Get results - null fields from above should be populated
            if (rs.first())
                myAppList = (UserAppList)rs.getObject("p_InOutRs");
                myAppArr = myAppList.getArray();
                System.out.println("status:   " + myAppArr[0].getStatus());
                System.out.println("desc str: " + myAppArr[0].getDescString());
                System.out.println("comments: " + myAppArr[0].getComments());
                // additional fields here..
            //MyObject[] myObjectAry = (MyObject[])p_myObjectArray.getArray();
            //cs.registerOutParameter(1,Types.CHAR);                      
        catch (Exception e)
            e.printStackTrace();
        finally
            if (conn != null)
            try { conn.close(); }
            catch (Exception e) {}
}So this code will compile and run up to the stored procedure call itself, but I'm not sure how to set the parameters for in/out with these generated classes. Any ideas?

Anyone? Still haven't figured this one out...
