trying to troubleshoot: WinFX service, Axis2 RC1 client using netTcpBinding and tcp transport respectively

I have a simple WinFX service that uses a bindingConfiguration on the netTcpBinding to turn off security. I can easily call this from a WinFX client, but I'm trying to communicate from an Axis2 RC1 client over TCP. The request is coming in [I can see if in SvcTraceViewer], I'm getting a System.ServiceModel.ProtocolException, which contains a System.IO.InvalidDataException. The innerException is: Expected record type 'Version', found '60'. at System.ServiceModel.Channels.ServerModeDecoder.Decode(Byte[] bytes, Int32 offset, Int32 size)

I'm just trying to do Java 2 WinFX interop over TCP. This should be possible, right If so, how can I turn off any MS-specific stuff in the netTcpBinding so that the incoming message from Java is accepted

Thanks in advance for any help. Please let me know if more information is needed.
