WCF Client Error “The connection was closed unexpectedly” Calling Java/WebSphere 7 Web Service

If you get the following exception calling a WebSphere web service from your .NET WCF Client (service reference):

System.ServiceModel.CommunicationException: The underlying connection was closed: The connection was closed unexpectedly. —>  System.Net.WebException: The underlying connection was closed: The connection was closed unexpectedly.

Try adding this code before the service call:

System.Net.ServicePointManager.Expect100Continue = false;

More info on the 100-Continue behavior from MSDN.
