Getting error when trying to expose the java class as webservice

Question

I am new to webservices and ESB.
I have two custom schemas. LegacyCustomer.xsd and CommonCustomer.xsd. I am compiling these schemas using JAXP. I am trying to map one custom data to another data using java class. I am trying to expose this java class into webservice.
public class Test implements Serializable {
private static final long serialVersionUID = 1L;
public Test() {
public CustomerType transform (CustomerDataType custDataType) {
CustomerType custType = new CustomerType();
custType.setCustomerId(custDataType.getCustomerId());
return custType;
Schemas used are:
Input Schema:
<schema targetNamespace="http://xmlns.oracle.com/Esb/CustomerData" xmlns:cust="http://xmlns.oracle.com/Esb/CustomerData" xmlns="http://www.w3.org/2001/XMLSchema">
     <element name="CustomerData" type="cust:CustomerDataType"/>
     <complexType name="CustomerDataType">
          <sequence>
               <element name="CustomerId" type="string"/>
</sequence>
     </complexType>
</schema>
Output Schema:
<schema targetNamespace="http://xmlns.oracle.com/Esb/CustomerProvision" xmlns:CU="http://xmlns.oracle.com/Esb/CustomerProvision" xmlns="http://www.w3.org/2001/XMLSchema">
     <element name="Customer" type="CU:CustomerType"/>
     <complexType name="CustomerType">
          <sequence>
               <element name="CustomerId" type="string"/>
          </sequence>
     </complexType>
</schema>
When I try to do this I am getting following error
CustomerType of method transform cannot be serialized into xml, and no custom serializer has been defined for it.
Why do we need custom serializer here? And if this is mandatory how can we define this custom serializer?

Thanks for your reply...
I tried second option that you specified first. I did the transformation of objects using xslt. It is working fine.
But I couldn't able to do this using first method...,
When I tried to compile the schema using jaxp it is actually creating classes without the private variables. and hence it is not able to recognize those variables to generate the wsdl.
But I am not sure how to generate the classes with those private variables and getter and setters (to generate wsdl specification it seems to be mandatory one).
Can you please tell me how can we do the schema compilation (other than xml beans and jaxp.... I tried both)?
