Question

I have an xsd (for basecamp xml) that contains

<xsd:complexType name="ProjectType">
    <xsd:sequence>
        <xsd:element name="announcement"
                     type="TypedNilableStringElementType"
                     maxOccurs="1" 
                     minOccurs="1">
        </xsd:element>
        <xsd:element name="created-on"
                     type="TypedDateElementType" 
                     maxOccurs="1"
                     minOccurs="1">
        </xsd:element>
        <xsd:element name="id"
                     type="TypedIntegerElementType" 
                     maxOccurs="1"
                     minOccurs="1">
        </xsd:element>
        <xsd:element name="last-changed-on"
                     type="TypedDateTimeElementType" 
                     maxOccurs="1"
                     minOccurs="1">
        </xsd:element>
        <xsd:element name="name" 
                     type="xsd:string" 
                     maxOccurs="1"
                     minOccurs="1">
        </xsd:element>
        <xsd:element name="show-announcement"
                     type="TypedBooleanElementType" 
                     maxOccurs="1"
                     minOccurs="1">
        </xsd:element>
        <xsd:element name="show-writeboards"
                     type="TypedBooleanElementType" 
                     maxOccurs="1"
                     minOccurs="1">
        </xsd:element>
        <xsd:element name="start-page" 
                     type="xsd:string"
                     maxOccurs="1" 
                     minOccurs="1">
        </xsd:element>
        <xsd:element name="status" 
                     type="xsd:string" 
                     maxOccurs="1"
                     minOccurs="1">
        </xsd:element>
        <xsd:element name="company"
                     type="SimpleCompanyType" 
                     maxOccurs="1" 
                     minOccurs="1">
        </xsd:element>
    </xsd:sequence>
</xsd:complexType>

and

<xsd:element name="project" 
             type="ProjectType">
</xsd:element>

I’m looking at http://java.sun.com/javaee/5/docs/tutorial/doc/bnbah.html and can’t understand what I’m doing differently from the sample schema in Table 17-13 where there is an element named purchaseOrder of type PurchaseOrderType. According to the tutorial, running xjc on the schema, one will get a PurchaseOrder.java interface and PurchaseOrderType.java interface.

When I run xjc on my schema I only get a ProjectType.java class, and when the xml actually consists of a single <project ...></project> element, this won’t parse because there is no Project.java class/interface to match.
