Problemas para criar Web Services com Axis2 + TomCat 6 + Eclipse Galileo

Bom dia pessoal,

Estou estudando o livro "Web Services SOAP em JAVA", mas estou tendo problemas.

Criei o projeto CalculadorWS.
Pacote org.ws.calc
Classe Calculadora.java

Criei o services.xml dentro da pasta resources/META-INF

Criei o build.xml na raíz do projeto

<?xml version="1.0" encoding="UTF-8"?>
<project name="Calculadora" basedir=".">
    <property environment="env"/>
    <property name="AXIS2_HOME" value="C:\axis2-1.5.1"/>
    <property name="build.dir" value="build"/>
    <path id="axis2.classpath">
        <fileset dir="${AXIS2_HOME}/lib">
            <include name="*.jar"/>
        </fileset>
    </path>
    <target name="compile.service">
        <mkdir dir="${build.dir}"/>
        <mkdir dir="${build.dir}/classes"/>
        <javac debug="on" fork="true" destdir="${build.dir}/classes"
            srcdir="${basedir}/src" Classpathref="axis2.classpath">
        </javac>
    </target>
    <target name="generate.wsdl" depends="compile.service">
        <taskdef name="java2wsdl" Classname="org.apache.ws.java2wsdl.Java2WSDLTask"
            Classpathref="axis2.classpath"/>
        <java2wsdl className="org.ws.calc.Calculadora"
            outputLocation="${build.dir}" targetNamespace="http://org.ws/"
            schemaTargetNamespace="http://org.ws/xsd">
            <classpath>
                <pathelement path="${axis2.classpath}"/>
                <pathelement location="${build.dir}/classes"/>
            </classpath>
        </java2wsdl>
    </target>
    <target name="generate.service" depends="compile.service">
        <copy toDir="${build.dir}/classes" failonerror="false">
            <fileset dir="${basedir}/resources">
                <include name="**/*.xml"/>
            </fileset>
        </copy>
        
        <jar destfile="${build.dir}/Calculadora.aar">
            <fileset excludes="**/Test.class" dir="${build.dir}/classes"/>
        </jar>
    </target>
    <target name="clean">
        <delete dir="${build.dir}"/>
    </target>
</project>

Após rodar o build.xml é gerado a pasta build no meu projeto e dentro da pasta estão os arquivos Calculadora.aar e Calculadora.wsdl.
O livro pede para copiar o arquivo Calculadora.aar para o diretório C:\Tomcat 6.0\webapps\axis2\WEB-INF\services

Aí dou start no TOMCAT e abro no internet explorer o link http://localhost:8080/axis2/services/listServices

Aí aparece no browser a pagina do Apache:

Back Home | Refresh

Available services

--------------------------------------------------------------------------------

Faulty Services
C:\Tomcat 6.0\webapps\axis2\WEB-INF\services\Calculadora.aar

Aí clico no link acima e aparece o erro:

Segundo o livro, deveria aparecer o nome do meu serviço(Calculadora) e os seus métodos: somar, subtração, divisão e multiplicação.

Por favor,

vocês poderiam ajudar a resolver esse problema?

Muito obrigado

Aqui tem um material bom.

Aqui tem outros.
