WCF app calling Java web service only serializes string members

I have a C# WCF service that is currently hosted in a Windows Forms application.  It communicates with two applications.  One application is an in-house managed C++ application that is fully WCF compatible and implements a callback interface for bidirectional communication.  That interface is working correctly.

The other application is a 3rd-party client's application written in Java.  It does not understand WCF, so I implemented a custom binding that uses Soap 1.2 to facilitate communicate from the Java app to my service.  That communication is working correctly.  Since a callback interface can't be supported, the 3rd-party client implemented a web service in Java to allow my service to 'call back' to his application.  This is where I'm having the problems.

The problem is that the body of the soap messages sent from my WCF service to the Java web service contain only string members of my types.  All 'int' and 'bool' members are missing.  This is not a WSDL issue - they are present in the WSDL and the auto-generated code created when the service reference is created contains all members - strings, ints and bools.

I've tried using both a web reference to access the Java web service and a service reference to reference the Java web service - I see the exact same result either way.

I did some googling and I know that I can switch from the DataContractSerializer to the XmlSerializer, but I really don't want to do that - my interface is large & there are a LOT of data contract items that would have to be reworked to use the XmlSerializer.

HELP!!!!  I have a real time-crunch to get this project completed and have run out of ideas.

I'm attaching a code snippet that contains the WSDL obtained from the Java web service & the SOAP that is generated (captured via tcptrace utility).  Note that I'm calling the method phoneNumbersRequest which takes a parameter of type OCPhoneNumbersRequest.

I have determined the solution to this issue.  When non-string class members are not marked as required, an additional xxxSpecified companion Boolean member is generated for each such member.  For instance, if a class contains an optional Int32 member named 'retries', when a WSDL is generated, the WSDL definition for the class will contain the 'retries' Int32 member and a 'retriesSpecified' Boolean member.

When using the class auto-generated from the WSDL, it is necessary to set both the retries member and the retriesSpecified member in order for the retries member to be serialized to the SOAP message.
