Hi,
I am using Axis 2 to communicate with a server which has ntlm authentication.
When I am invoking web service methods which do not involve any attachment, it
is working fine. Using TCP packet capturing, I can even see the NTLM
authentication happening via challenge/response handshaking. One problem that I
see here is that for every method invocation the ntlm authentication is
occuring which is a kind of redundancy. I think this is happening because
pre-authentication feature is not built into Axis 2 or common httpclient.
But the more serious problem is happening when I am trying to post data as
attachment. The entire SOAP request is sent as a multipart MIME-encoded
request. The first part is the SOAP envelope, and the second part is the
attachment. But as it seems to me the ntlm authentication handshaking is
getting into way and the client is not responding accordingly and is continuing
with its multipart post. I am using Axis 2-1.1.1 version. The authentication
code used is like below:
HttpTransportProperties.Authenticator auth = new
HttpTransportProperties.Authenticator(); auth.setUsername("Admin");
auth.setPassword("<password>"); auth.setRealm(""); auth.setDomain("");
auth.setHost("<ip-addr>"); auth.setPort(80);
options.setProperty(HTTPConstants.AUTHENTICATE, auth);
options.setProperty(HTTPConstants.HEADER_CONNECTION_KEEPALIVE,Constants.VALUE_TRUE);
options.setTo(targetEPR);
options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
options.setProperty(Constants.Configuration.ENABLE_MTOM,Constants.VALUE_TRUE);
options.setProperty(Constants.Configuration.CONTENT_TYPE,
Constants.BASE_64_CONTENT_QNAME); ServiceClient servClient = new
ServiceClient(); servClient.setOptions(options); OMElement result =
servClient.sendReceive(method);
I am new to Axis and authentication. Any suggestion would be of great help.
