Schema generation problem with JAXB

[metro-3]

Hi,

I am using annotations to customize the XML schema generated by JAXB. I have a scenario where there are multiple occurances of the same element name "product" but not at the same level. In the example below I have a "product" under "Result" which is of type "ProductA". I also have a "product" under "Store" which is of type "ProductB". But the schema generated by JAXB creates a single "product" with type "xs:anyType" (In schema1.xsd). This is causing problem during marshalling and unmarshalling.

Is there a way to configure JAXB to not use references ([i]<xs:element ref="ns1:product"/>[/i]) to other schema but rather define the element in the main schema itself (like: [i]<xs:element name="product" type="productA" minOccurs="0"/>[/i])?? That would solve my problem.

[u]Following are the java files being used for this example:[/u]
[b]1) ProductA.java:[/b]
public class ProductA {
}
[b]2) ProductB.java:[/b]
public class ProductB {
}
[b]3) Store.java:[/b]
@XmlType(name = "Store")
public class Store {
    private ProductB product;

    @XmlElement(name = "product", type = ProductB.class, required = true, namespace = "java:com.test")
    public ProductB getProduct() {
        return product;
    }

    public void setProduct(ProductB product) {
        this.product = product;
    }
}
[b]4) Result.java:[/b]
@XmlType(name = "Result")
public class Result {
    private ProductA product;
    private Store store;

    @XmlElement(name = "product", type = ProductA.class, required = true, namespace = "java:com.test")
    public ProductA getProduct() {
        return product;
    }

    public void setProduct(ProductA product) {
        this.product = product;
    }

    @XmlElement(name = "store", required = true, namespace = "java:com.test")
    public Store getStore() {
        return store;
    }

    public void setStore(Store store) {
        this.store = store;
    }
}

[u]Following are the schema files generated by JAXB:[/u]
[b]1) schema1.xsd:[/b]
<xs:schema version="1.0" targetNamespace="java:com.test" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:import schemaLocation="schema2.xsd"/>
  <xs:element name="product" nillable="true" type="xs:anyType"/>
  <xs:element name="store" type="Store"/>
</xs:schema>
[b]2) schema2.xsd:[/b]
<xs:schema version="1.0" xmlns:ns1="java:com.test" xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:import namespace="java:com.test" schemaLocation="schema1.xsd"/>

  <xs:complexType name="Store">
    <xs:sequence>
      <xs:element ref="ns1:product"/>
    </xs:sequence>
  </xs:complexType>

  <xs:complexType name="productB">
    <xs:sequence/>
  </xs:complexType>

  <xs:complexType name="Result">
    <xs:sequence>
      <xs:element ref="ns1:product"/>
      <xs:element ref="ns1:store"/>
    </xs:sequence>
  </xs:complexType>

  <xs:complexType name="productA">
    <xs:sequence/>
  </xs:complexType>
</xs:schema>

In other words is it possible to configure JAXB to not generate multiple schemas but to generate just one schema file?

Thanks for your time and I appreciate any suggestions.
