WCF Callback: Is it interoperable with Java?

No WSDualHttpBinding and CompositeDuplexBindingElement are not interoperable with Java.

No. WSDualHttpBinding and CompositeDuplexBindingElement are not interoperable with Java. Edit: As pointed by @x0n the original blog post referenced in my answer is not 100% correct.

There is a newer blog post describing the way how to achieve interoperability. As I understand it the approach is similar to using service with asynchronous response correlated through WS-Addressing (WCF doesn't support this exchange model in normal processing). WsDualHttpBinding uses some additional features like WS-ReliableMessaging and it also makes the service stateful.

I'm not sure if the described approach will work in all cases because it still talks about one-way messages but duplex communication in WCF can use both one-way and two-way message exchange patterns in both service and callback contracts.

NET Framework. – Ladislav Mrnka Oct 13 '10 at 13:12 1 Reviving an old question here, but actually, the wsdualhttpbinding binding is compatible with java stack (i've tested metro,) but the callbackcontract part is not (the declaration on the servicecontract.) A subtle difference.

You can use that binding, but on the java side you have to dig out the ws-addressing replyto header with a message handler and act on it. – x0n Sep 29 at 17:38.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
