How to export all the product data using ycommerce webservices?

Hi , The ycommerce webservices export full (../products/export/full) is not retrieving all the product data.Its just returning category code (and uri) and product code (and uri) for all the 40 created products. How to retrieve all the product data as well the composed type data in this export? And also even if the @Produces(application/xml) is anotated to the method, the response is always Json. How to get XML response? Kindly help me to resolve this issue. Thank you.
