用WCF和Java编写的Web服务

Question

Can I write a web service that implements the same methods and returns the same custom objects using both C#/WCF and also Java Web Services? And if so, can I then access the web services using a single web reference but with different addresses?

I'm asking because I have to host a web service that has a GetCitations and GetTerms method for publically exposing our database content. We are on IIS, so I was going to do it with WCF. However, other partners in the project also have to host an equivalent service and they are all Java based.

We are then building a software app that needs to connect to any number of these services (as defined at runtime by a user). I am expecting that we can have one set of classes to connect to these services (but with different endpoitn addresses), but am not sure whether I'm right in expecting this to work.

Is this possible? And what considerations/restrictions are there?

Thanks.

Answer 1

It shouldn't be a problem, if you make sure that both services have equivalent wsdl files and you use http/soap binding.

I am not sure about using the binary (net.tcp) one with WCF, though. It might be a problem.

Answer 2

One way to do it is to use JAX-WS (Java 6) to expose a method as a web service.

The JAX-WS stack allows for automatically generating the correct WSDL at runtime.

The .NET team can then take that WSDL, and use standard tools to create a mock implementation of that WSDL. This mock implementation is then used as the actual .NET implementation, and you then use standard tools to generate the WSDL for that web service.

You now have to web services with the same semantics each with their own WSDL.

Answer 3

Java和.NET都可以实现SOAP兼容的Web服务，因此答案是肯定的，您可以编写实现相同WSDL的.NET和Java Webservice。
