JAXB xjc.sh NOT generating Interfaces

[whitteng]

I have been going through the Sun JAXB tutorial:

http://java.sun.com/webservices/docs/1.6/tutorial/doc/index.html

and using xjc.sh to compile the sample po.xsd shcema:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="purchaseOrder" type="PurchaseOrderType"/>
<xsd:element name="comment" type="xsd:string"/>
<xsd:complexType name="PurchaseOrderType">
<xsd:sequence>
<xsd:element name="shipTo" type="USAddress"/>
<xsd:element name="billTo" type="USAddress"/>
<xsd:element ref="comment" minOccurs="0"/>
<xsd:element name="items" type="Items"/>
</xsd:sequence>
<xsd:attribute name="orderDate" type="xsd:date"/>
</xsd:complexType>

<xsd:complexType name="USAddress">
<xsd:sequence>
<xsd:element name="name" type="xsd:string"/>
<xsd:element name="street" type="xsd:string"/>
<xsd:element name="city" type="xsd:string"/>
<xsd:element name="state" type="xsd:string"/>
<xsd:element name="zip" type="xsd:decimal"/>
</xsd:sequence>
<xsd:attribute name="country" type="xsd:NMTOKEN"
fixed="US"/>
</xsd:complexType>

<xsd:complexType name="Items">
<xsd:sequence>
<xsd:element name="item" minOccurs="1"
maxOccurs="unbounded">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="productName"
type="xsd:string"/>
<xsd:element name="quantity">
<xsd:simpleType>
<xsd:restriction base="xsdositiveInteger">
<xsd:maxExclusive value="100"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="USPrice" type="xsd:decimal"/>
<xsd:element ref="comment" minOccurs="0"/>
<xsd:element name="shipDate" type="xsd:date"
minOccurs="0"/>
</xsd:sequence>
<xsd:attribute name="partNum" type="SKU"
use="required"/>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>

<!-- Stock Keeping Unit, a code for identifying products -->
<xsd:simpleType name="SKU">
<xsd:restriction base="xsd:string">
<xsdattern value="\d{3}-[A-Z]{2}"/>
</xsd:restriction>
</xsd:simpleType>

</xsd:schema>


It is SUPPOSED to generate:

Public interface
Comment.java

Public interface
Items.java

Public class
ObjectFactory.java

Public interface
PurchaseOrder.java

Public interface
PurchaseOrderType.java

Public interface
USAddress.java

Implementation of Comment.java.
CommentImpl.java

Implementation of Items.java
ItemsImpl.java

Implementation of PurchaseOrder.java
PurchaseOrderImpl.java

Implementation of PurchaseOrderType.java
PurchaseOrderTypeImpl.java

Implementation of USAddress.java
USAddressImpl.java


it DOES generate:
Items.java ObjectFactory.java PurchaseOrderType.java USAddress.java

I am only using things from the tutorial - none of my own stuff. Can
someone explain
what the difference is - why no interface files are being generated.

Thanks,
