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
[code]package org.ws.calc;
public class Calculadora {
// Efetua a soma de dois números
public double Soma(double i, double j){
double resultadoSoma;
resultadoSoma = i + j;
return resultadoSoma;
}
// Efetua a subtração de dois números
public double Subtracao(double i, double j){
double resultadoSubtracao;
resultadoSubtracao = i - j;
return resultadoSubtracao;
}
// Efetua a multiplicação de dois números
public double Multiplicacao(double i, double j){
double resultadoMultiplicacao;
resultadoMultiplicacao = i * j;
return resultadoMultiplicacao;
}
// Efetua a divisao de dois números
public double Divisao(double i, double j){
double resultadoDivisao;
resultadoDivisao = i / j;
return resultadoDivisao;
}
}
[/code]
Criei o services.xml dentro da pasta resources/META-INF
<?xml version="1.0" encoding="UTF-8"?>
<service name="Calculadora" scope="application" targetNamespace="http://org.ws/">
<description>
Calculadora Service
</description>
<messageReceivers>
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"

</messageReceivers>
<schema schemaNameSpace="http://org.ws/xsd"/>
<parameter name="ServiceClass">org.ws.calc.Calculadora</parameter>
</service>
Criei o build.xml na raíz do projeto
<?xml version="1.0" encoding="UTF-8"?>
<project name="Calculadora" basedir=".">

<property name="AXIS2_HOME" value="C:\axis2-1.5.1"/>

<target name="generate.service" depends="compile.service">
<copy toDir="${build.dir}/classes" failonerror="false">

</fileset>
</copy>
<!-- Nesta parte devemos fornecer o nome do arquivo aar -->
<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
