Answer 1

It looks like that the Axis client does not like the NTLM authentication challenge. See error message at the top:

Discarding unexpected response: HTTP/1.1 100 Continue

After which there is no XML for Axis to parse, which is why you're getting premature end of file.

In order to use NTLM with Axis (1.4), you'll have to use the CommonsHTTPSender instead of the standard transport:

<transport name="http" pivot="java:org.apache.axis.transport.http.CommonsHTTPSender">
</transport>

in your client-config.wsdd and then set up the NTLM username and password through the Stub object.

The "premature end of file" type errors from the xerces SAX implementation usually indicates that the SAX parser expected data, but got none (not null , but an initialized empty InputSource ). From the stack trace, it looks as if the axis SOAP handler expects a SOAP xml message to arrive, but the message is empty. My knowledge of ISS and its infrastructure is close to nil, can you get any log messages from the server?
