Help wanted to diagnose an xsd error in running Java code generator

[Shaoguang Cong]

I'm fairly new to jaxme and tried first to run an example. I copied the Ant task from "The JaxMe 2 manual" and modified a little with the paths.  I also added a <project> tag to the ant build file because it gives an error  "Unexpected element "target" target" when I first compiled it.   I don't know why it complains my XSD about "the type bookType is not defined."   It looks the bookType is defined.  Here's the error message:   "build.xml" 31: At file:/C:/jaxme/books.xsd, line 11, column 93: At file:/C:/jaxme/books.xsd, line 11, column 93: Invalid element: The type bookType is not defined. at line 31   The schemas file is pasted below.  The Ant file is pasted at the end too.   Thank you for any help.   Shaoguang   <?xml version="1.0" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"   targetNamespace="com.jaxme"   jaxb:version="1.0">   <xs:element name="Collection">     <xs:complexType>       <xs:sequence>         <xs:element name="books">           <xs:complexType>             <xs:sequence>               <xs:element name="book" type="bookType" minOccurs="1" maxOccurs="unbounded" />             </xs:sequence>           </xs:complexType>         </xs:element>       </xs:sequence>     </xs:complexType>   </xs:element>   <xs:complexType name="bookType">     <xs:sequence>       <xs:element name="name" type="xs:string" />       <xs:element name="ISBN" type="xs:long" />       <xs:element name="price" type="xs:string" />       <xs:element name="authors">         <xs:complexType>           <xs:sequence>             <xs:element name="authorName" type="xs:string" minOccurs="1" maxOccurs="unbounded" />           </xs:sequence>         </xs:complexType>       </xs:element>       <xs:element name="description" type="xs:string" minOccurs="0" />       <xs:element name="promotion">         <xs:complexType>          <xs:choice>            <xs:element name="Discount" type="xs:string" />            <xs:element name="None" type="xs:string" />          </xs:choice>         </xs:complexType>       </xs:element>       <xs:element name="publicationDate" type="xs:date" />       <xs:element name="bookCategory">         <xs:simpleType>         <xs:restriction base="xs:NCName">           <xs:enumeration value="magazine" />           <xs:enumeration value="novel" />           <xs:enumeration value="fiction" />           <xs:enumeration value="other" />         </xs:restriction>         </xs:simpleType>       </xs:element>     </xs:sequence>     <xs:attribute name="itemId" type="xs:string" />   </xs:complexType>     <xs:simpleType name="bookCategoryType">     <xs:restriction base="xs:string">       <xs:enumeration value="magazine" />       <xs:enumeration value="novel" />       <xs:enumeration value="fiction" />       <xs:enumeration value="other" />     </xs:restriction>   </xs:simpleType> </xs:schema>   // Ant file   <?xml version="1.0" ?> <project name="generic" default="task1" basedir="."> <target name="task1">  //<target name="taskdef">         <path id="com.jaxme">         <pathelement location="C:\ws-jaxme-0.5\ws-jaxme-0.5\lib\jaxme2-0.5.jar"/>         <pathelement location="C:\ws-jaxme-0.5\ws-jaxme-0.5\lib\jaxmejs-0.5.jar"/>         <pathelement location="C:\ws-jaxme-0.5\ws-jaxme-0.5\lib\jaxmexs-0.5.jar"/>         <pathelement location="C:\ws-jaxme-0.5\ws-jaxme-0.5\lib\jaxmeapi-0.5.jar"/>       </path>             <taskdef name="xjc"         classname="org.apache.ws.jaxme.generator.XJCTask"         classpathref="com.jaxme"/>              <xjc schema="c:/jaxme/books.xsd"  target="c:/jaxme/src">         <produces includes="com/jaxme/*.java"/>       </xjc>     </target> </project>
