C# calling JAVA web service - results are null

[Guest]

I have a simple c# app that calls a Java (AXIS) web service to perform some
operations. The call works fine (the java code fires and the operations are
executed), but the response is always null. Other applications (besides the
c# ones) are able to execute the web service and get the proper response.

I put a SOAP sniffer on the call and the response was:
193
<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><synchronousInvokeResponse
xmlns="http://DefaultNamespace"><processID xsi:type="xsd:long"
xmlns="">205</processID></synchronousInvokeResponse></soapenv:Body></soapenv:Envelope>
0

</Message>

I'm not sure where the 193, 0 and </Message> came from but I suspect that it
was caused by some chunking issues.

The response header is as follows:
<HTTPHeaders>
<content-type>text/xml;charset=utf-8</content-type>
<transfer-encoding>chunked</transfer-encoding>
<date>Wed, 26 Apr 2006 19:07:26 GMT</date>
<server>Apache-Coyote/1.1</server>
</HTTPHeaders>


Any thoughts on how I can get the c# application to properly recognize the
response? Unfortunately I can't change the Java web service.


The Java web service WSDL is as follows:

that's really wiered. what does the java web service send back? Is it a
custom type or something else? If it is a custom type, you may want to have
your code create an object of the custom type. I can't really say that an
exception is thrown because the exception would be wrapped in a
soapexception object and your code would fall over dead on your side. you
say that if you call the same service from a none c# app, you get back the
correct results? the mystery deepens...

The java web service retruns a xsd:long object, so I wouldn't think that it
would be a problem
