Calling C# web service (soap.tcp) from Java

[TayBill]

I have C# based webservice that is hosted in a NT service. Programmatic access to the web service is of the form: soap.tcp://localhost:11141/ProcessorWebService

(The more traditional way to implement C# webservices is to put them in asp.net (.asmx) files and hosted by IIS. Access to these services is of the form: http://localhost/webservicetest/service.asmx. For various reasons, I don’t want to do that.)

I can successfully connect to my web service by from C# by:
1. Creating a C# proxy for the webservice by running WseWsdl.exe against the URL.
2. Make calls using the proxy’s.
My initial problem: How do I connect to the service from Java?
Problems I’ve encountered
1. How to create a proxy in Java?
a. I want to use wsimport against a WSDL file. But, since I don’t have a .asmx based service, I can’t just call <url>?WSDL to get it.
2. Even if I create a Java proxy (which I’ve done via some judicious hacking), I can’t seem to successfully connect to the service, when the URL is of the form soap.tcp://localhost:11141/ProcessorWebService.
a. The big difference her is using soap.tcp as the protocol, instead of HTTP. Also note that I’m going to a non traditional port. Still—I can get all of this to work from C#.

Here’s an example of my trivial program:
ProcessorWebService pws = new ProcessorWebService();
ProcessorWebServiceSoap pwss = pws.getProcessorWebServiceSoap(); ((javax.xml.ws.BindingProvider)pwss).getRequestCon text().
put(javax.xml.ws.BindingProvider.ENDPOINT_ADDRESS_ PROPERTY, "soap.tcp://localhost:11141/ProcessorWebService");

String resultFromHelloWorld = pwss.helloWorld();
It fails on the call to pwss.helloWord(); with the following:
"Unsupported endpoint address: soap.tcp://localhost:11141/ProcessorWebService"

My real questions:
Is it even possible to connect Java to a webservice hosted in a NT service?
Does anyone have any good pointers, or examples. (I’ve searched around a lot, but I’m a novice at Java, so easily could have missed something.)

If upgrading to WCF is an option, you can use SOAP/TCP as a non-HTTP transport that is Java interoperable. SOAP/TCP is available in WCF-Xtensions.

Interesting idea, but my organization is probably too cheap to buy that package.

I don't think that you need to purchase anything to accomplish what you need. Check out this article on Developing Web Services. There is a section there that describes how to implement a client that consumes a web service using Java. It's pretty cool stuff... You create a stub, dynamic proxy, or use Dynamic Invocation Interface to consume your service. It's all described in that article with code examples.

Most of this stuff depends on a WSDL so I hope that you didn't create a RESTful web
service...because I'm not sure how you would use them in Java.

Here's another article that is pretty helpful: Creating a Simple Web Service and Client with JAX-WS.

You should probably search the sun website for Java related development :)
It's kind of like MSDN but not quite as...robust.

Unfortunately, the link you provided is an all Java solution. I'm constrained that my service is written in C# AND is hosted in an NT service (as opposed to the more traditional asmx page in IIS).

I'm starting to think that the big clue that I "can't get there from here", is that I can't fine a way to generate WSDL from my solution. All the solutions I find, including the one you referenced, rely on a WSDL file being available.

I misunderstood your problem. I thought that you didn't know how to consume a web service in Java....

I haven't worked much with web services in .NET before but have you tried "publishing" the web service to a server?
