JAX-rpx document literal type web services

Question

I was trying to create a Document centric Web service. I followed all the steps in the document "Patterns and Designs for Building Document based Web Services" available at java.sun.com. I created the XSD's and WSDL files (top down approach). i used the following command of wscompile tool to generate the java source code.
wscompile -import -d build/classes -keep -s build/src -model build/model.xml.gz
to publich the web service on a server.
When the tool generates the code, the parameters for the method are the elements of the schema, instead of being an object, specified in the WSDL.
// This class was generated by the JAXRPC SI, do not edit.
// Contents subject to change without notice.
// JAX-RPC Standard Implementation (1.1.2_01, build R29)
// Generated source version: 1.1.2
package com.galaxyplus.tranentry.services;
public interface IPurchaseOrder extends java.rmi.Remote {
    public com.galaxyplus.tranentry.services.PurchaseOrderStatus acceptPO(com.galaxyplus.tranentry.services.Address billTo, java.util.Calendar createDate, com.galaxyplus.tranentry.services.LineItem[] items, java.lang.String poID, com.galaxyplus.tranentry.services.Address shipTo) throws
         java.rmi.RemoteException;
}It was supposed to be
// This class was generated by the JAXRPC SI, do not edit.
// Contents subject to change without notice.
// JAX-RPC Standard Implementation (1.1_03, build R65)
package com.examples.docliteral;
public interface IPurchaseOrder extends java.rmi.Remote {
    public com.examples.docliteral.PurchaseOrderStatus
         acceptPO(com.examples.docliteral.PurchaseOrder parameters) throws
             java.rmi.RemoteException;
}Does any one have any inputs on this. I am using the same example as in the Document.
Thanks
