为了使用RPC web服务，首先我必须调用web方法'Authentication'，然后我应该能够调用其他web方法。我已经尝试实现一个spring web客户端来使用这个服务，但是有些事情是非常错误的。
这个服务最初是为php用户设计的，他们提供的示例客户端代码如下:
$soap = new SoapClient('http://www.2972.ir/wsdl?XML');
if ($soap->Authentication('user', '123456')) {
echo $soap->getCredit();
}
'authentication'方法成功时将返回1，否则返回-1。'getCredit'方法返回显示用户当前余额的浮点数。
现在我在Java中的实现:
@Service
public class MessageService implements IMessageService {
@Autowired
private IranSMSPanelPortType webService;
public String doSomething() {
int status = webService.authentication("user", "123456");
System.out.println("# status: "+status);
return String.valueOf(webService.getCredit());
}
我得到的状态码等于'1'，但在调用第二个web方法时，我得到这个异常:
javax.xml.ws.soap.SOAPFaultException: You are not authorized
很明显，在php中调用'authentication'方法与在java中调用它没有相同的效果。于是我又调查了一下，发现在'authentication' web方法的响应cookie中设置了一些东西。
下面是响应的概览:

可以看到PHPSESSID已经被赋值了!这个参数很可能是用来处理授权的。
给定以下Spring Web Service配置，我如何实现相同的结果?
<bean id="smsWebService" class="org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean">
<property name="serviceInterface" value="com.iransmspanel.IranSMSPanelPortType" />
<property name="wsdlDocumentUrl" value="http://www.2972.ir/wsdl?XML" />
<property name="namespaceUri" value="http://www.iransmspanel.com/" />
<property name="serviceName" value="IranSMSPanel" />
<property name="portName" value="IranSMSPanelPort" />
</bean>
如果需要处理身份验证，我欢迎web服务客户端的其他实现。
我最终设法解决了这个问题，使用自定义的SAOP-Handler并手动从消息Http Headers中提取PHPSESSID。
