Question

我正在从vb .net客户端使用java web服务。此服务返回一个对象（称为serviceResponse），该对象具有三个字段：一个整数和两个字节数组

Dim serviceResponse As MyWebService.serviceResponse = mVaultWebService.downloadData(inputBuffer)

当返回的数据量很小时，一切正常，但是当数据量很大时，我得到以下异常（在客户端）

Timeouts are not supported on this stream.

这是堆栈跟踪

这是Web服务的配置方式

Dim binding As New BasicHttpBinding()
binding.MessageEncoding = WSMessageEncoding.Mtom
binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic
binding.MaxReceivedMessageSize = Integer.MaxValue
binding.MaxBufferSize = Integer.MaxValue
binding.SendTimeout = New TimeSpan(0, 10, 0)
binding.ReceiveTimeout = New TimeSpan(0, 10, 0)
Dim address As New EndpointAddress(urlAddress)

mWebService = New MyWebService.WSClient(binding, address)
mWebService.ClientCredentials.UserName.UserName = username
mWebService.ClientCredentials.UserName.Password = password

我无法弄清楚导致此问题的原因，似乎绑定设置或某些配置属性未正确设置。关于如何解决这个问题的任何想法？
