org.apache.axis2.AxisFault：传输错误：404 错误：

如何解决org.apache.axis2.AxisFault：传输错误：404 错误：

我在 JAX WS 中编写了一个客户端代码来访问 informatica Webservice，这是一个服务器端代码。我正在使用基于 SOAP 的网络服务。客户端之前正在工作并且能够从服务器获得响应，但突然间我开始收到以下错误。我在下面附上代码和堆栈跟踪.. 我使用 wsimport 命令生成存根文件.. 非常感谢任何帮助。

代码******

PaymentMethodsByCustomerIdsV1PortType port = getPaymentMethodsByCustomerIdsV1Service();
PaymentMethodsByCustomerIdsV1Request request = new PaymentMethodsByCustomerIdsV1Request();

Map<String,Object> req_ctx = ((BindingProvider)port).getRequestContext();
req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,informatica_endpoint);
req_ctx.put(BindingProvider.USERNAME_PROPERTY,AppProperties.getInstance().getProperty("informatica.username"));
req_ctx.put(BindingProvider.PASSWORD_PROPERTY,AppProperties.getInstance().getProperty("informatica.password"));
HashMap<String,String> customerBankData = new HashMap<String,String>();
List<PaymentMethodsType> paymethodsTypelist;

request.setCustomerIds(customerNumber);
System.out.println("**** Endpoint URL *****" +informatica_endpoint);
PaymentMethodsByCustomerIdsV1Response response = port.paymentMethodsByCustomerIdsV1(request);
List<PaymentMethodsByCustomerIdsResponseType> ctr = response.getPaymentMethodsByCustomerIdsResponse();

下面的堆栈跟踪错误*
