Consume Java Web Service from C# client

[Valeriu Filip]

Hello,

I have a java web service, and created a wsdl file from the java class;
based on the resulting wsdl file i generated the proxy C# class using
wsdl.exe utility and the result i included in my window app.
i am calling the web method but, i get no answer back, and after 1,2 minutes
i get something like 'Operation time out'. if i check on the server where it
runs the java web service, the method was called and parameters corectly
passed, so i don't understand why it does not return from the
function-procedure.
with a java client everything works.

thank you very much!

Have you got network traces of the incoming and outgoing messages?
Something like proxytrace will do, if you are going over HTTP ?

if the question, is if i am going over a proxy, then yes.
second i've made a test with a java service and my c# client in my local
network (no proxy between) and works fine.
the 'proxytrace' i never heard of; but i know tracert; still i don't see
what is the help.
i've also read other kind of problems, and i don't know if it is true and if
migth be my case: my proxy and the proxy that is in front of the java web
service use diff protocols (Http1.0 and Http1.1)

thanks.

Have you tried to force the .NET client that goes through the proxy to use
HTTP 1.0 , rather than HTTP 1.1 ? Or turn off Keep-Alive.

see here:
http://weblogs.asp.net/jan/archive/2.../28/63771.aspx
proxytrace is a tool based on tcptrace that helps trace web services
requests. http://www.pocketsoap.com/tcptrace/pt.aspx It may be of no use
to you, since you need a proxy anyway. But there are other webservice
network trace tools. Eg, Fiddler,
http://www.bayden.com/fiddler/ and HTTP Sniffer
http://www.effetech.com/sniffer/

tracert is something different

You may be able to twiddle the HTTP requests with one or more of these
tools, to try out the effects of turning on/off HTTP1.1 and Keep-alive.
