XMLDB Web Services being consumed by VB .Net

Hi,

I posted this question under the XML Database community and have been referred here.

I have created a web service that returns a collection of records that needs to be consumed .Net using VB code.

The details of the web service, wsdl and problem are as follows: 

Create XMLDB Web Service:

1. Create a user defined object type that will serve as a record.

2. Create a user defined table type that will hold these records.

3. Create a user defined object type that will hold the table type.

4. Create the pl/sql function that will populate and return the object containing the table.
