temp fix for NTML authentication & axiom serialization error
Hi guys,
I had to make my client work, so I digged into the code and "fixed" it. It's
just something for me to bypass the problem. Maybe someone could take a look
and provide a real fix?
Basically, first is "NTLM scheme can't use UsernamepasswordCredential"
error.
I changed the AbstractHttpSender.java. I use NTCredential when there is
"realm" defined. I am sure there is
if (basicAuthentication.getRealm() == null)
{
defaultCredentials = new UsernamePasswordCredentials(
basicAuthentication.getUsername(),
basicAuthentication.getPassword());
}else
{
defaultCredentials = new NTCredentials(
basicAuthentication.getUsername (),
basicAuthentication.getPassword(),
basicAuthentication.getHost(),
basicAuthentication.getRealm());
agent.getState().setCredentials(new AuthScope(
basicAuthentication.getHost(),
basicAuthentication.getPort(),
null), defaultCredentials);
return;
}
However, I still got this error.
ERROR [main] (WSS.java:53) - problem accessing the parser. Parser already
accessed!; nested exception is:
javax.xml.stream.XMLStreamException: problem accessing the parser.
Parser already accessed!; nested exception is:
org.apache.axis2.AxisFault: problem accessing the parser. Parser already

Parser already accessed!; nested exception is:
org.apache.axis2.AxisFault: problem accessing the parser. Parser already
accessed!; nested exception is:
javax.xml.stream.XMLStreamException: problem accessing the parser.
Parser already accessed!
The error came from the handshake (The second time call to
HttpMethodDirector.java inside HttpClient package) After further digging, I
found it's not really Axis core module's issue. The error came from Axiom.
It failed in StAXBuilder.java:
public Object getParser() {
if (parserAccessed) {
throw new IllegalStateException(
"Parser already accessed!");
}
I really don't want to find out why, but tried to see whether serializing
into a string would work. So I added the following call to
org.apache.axiom.om.impl.llom.OMElementImpl.java::internalSerialize();
try
{
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
this.serialize(buffer);
buffer.close();
System.out.println(buffer.toString());
}catch(Exception e)
{
System.out.println(e.getMessage());
}
Magically, it "fixed" the problem! Now the authentication went through and
everything works fine!
Here I attached the two files. Can someone please look into the problem?

Ajith,
I tried it. The NTLM seems to be working. However, OM part is still not. Has
it been fixed in last night's build?
My "fix" of the OMElement doesn't work for some other situations. It throw
NULLPointer exception while processing some other returns. Shall I file
another bug?
Thanks,
Jeff

Re: [Axis2] temp fix for NTML authentication & axiom serialization error

Hi Saminda,
Is this the perfect solution. The reason is that if you look at HttpClient
code, you will notice that whether to use Basic or NTLM, it is resolved at
runtime. (There is a message of "NTLM scheme selected" or something like
that.
Let's say the user specifies "domain/user, password", I guess the best
solution is to dynamically decide whether to use NTLM and Basic. In another
words, with the same input, based on handshake response from server, the
client decide whether to use NTCredential or UsernamePasswordCredential.
Another benefit is that if Kerberos or Digest is supported, then the user's
code doesn't have to change. Otherwise user (like me) has to write
HttpTransportProperties
>
> .DigestAuthentication dgiestAuthentication =
> new HttpTransportProperties().new
> DigestAuthentication();
Plus, it's the server admin who decides what auth scheme to use, or
simultaneous allow multiple. If the client code/configuration has to change,
it's very inconvenient.

Jeff

Re: [Axis2] temp fix for NTML authentication & axiom serialization erro
Posted by Saminda Abeyruwan <sa...@gmail.com>.
Axis2 uses HttpClient's NTLM support. Your code snippet looks good, and
wonder if you have given the credentials according to
http://commons.apache.org/httpclient/authentication.html#NTLM
In addition to the above, you've need to set
auth.setAllowedRetry(true);
Please comment out
auth.setHost("hostname");
auth.setPort(80);

Hi
I am trying to use a webservice written in .net, for Sharepoint Portal.
Am using axis2-1.3
Have generated WebService client using eclipse pluggin
In the generated class ServiceServiceSoapStub looks like this,
//.....snippet
OperationClient _operationClient =
_serviceClient.createClient(_operations[0].getName())
//.....
_serviceClient.addHeadersToEnvelope(env);
_messageContext.setEnvelope(env);
HttpTransportProperties.Authenticator auth = new
HttpTransportProperties.Authenticator();
auth.setUsername("username");
auth.setPassword("password");
auth.setDomain("domain");
auth.setHost("hostname");
auth.setPort(80);
_operationClient.getOptions().setProperty(org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE,auth);
_operationClient.addMessageContext(_messageContext);
System.out.println(((HttpTransportProperties.Authenticator)_operationClient.getOptions().getProperty(org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE)).getUsername());
//execute the operation client
_operationClient.execute(true);
// .....
I am getting 401 exception

Can we use options for NTML authentication and set it to OperationClient
object?
Or is there something I am missing out here :(

Hi Jeff, Dims, Paul and all,
To do NTLM Authentication one has to do the following now,
...
<snippet/>
HttpTransportProperties.NTLMAuthentication ntlmAuthentication =
new HttpTransportProperties().new NTLMAuthentication();
ntlmAuthentication.setUsername("axis2");
// other credentials.
options.setProperty(
org.apache.axis2.transport.http.HTTPConstants.NTLM_AUTHENTICATION,
ntlmAuthentication);
...
To do Basic Authentication one has to do the following,
...
<snippet/>
HttpTransportProperties.BasicAuthentication basicAuthentication =
new HttpTransportProperties().new BasicAuthentication();
basicAuthentication.setUsername("axis2");
basicAuthentication.setPassword("axis2");
options.setProperty(
org.apache.axis2.transport.http.HTTPConstants.BASIC_AUTHENTICATION,
basicAuthentication);
...
Jeff, please try it and let us know the results. Will update the docs asap.
Thank you
Saminda

Hi Dims,
Thanks a lot!
When would it be patched? And what's the plan for the next stable release?

Jeff,
Yep. that's the one. Basically http client tries to send the data and
when it fails tries to send it again. serializeAndConsume by design
does not cache the information (does not build the om tree). This is
good news just replacing one for the other. We'll take this account
and may be add a flag for this behavior.
Thanks,

Hi Paul,
I assume you meant the
element.serializeAndConsume(bytesOut, format);
in public byte[] writeBytes()
right? No, that didn't work. However, following your lead, I changed the
same function in
private void handleOMOutput(OutputStream out, boolean doingMTOM)
throws XMLStreamException {
format.setDoOptimize(doingMTOM);
element.serializeAndConsume(out, format);
}
to
private void handleOMOutput(OutputStream out, boolean doingMTOM)
throws XMLStreamException {
format.setDoOptimize(doingMTOM);
element.serialize(out, format);
}
That fixed it. Maybe we are using different versions so the line count is
different? Please confirm.
This is great!

We have an idea :-) Can you help us test if its any good?
Can you please try this fix:
At line 194 in org.apache.axis2.transport.http.SOAPOverHTTPSender.
Please change
element.serializeAndConsume(out, format); to
element.serialize(out, format);
If that works for you then we can craft a proper fix around this.
Thanks

Hi Ajith and Paul,
Yes, it sounds right: Parser was accessed when not supposed to be, so a
calling sequence might be the reason.
Thanks for taking care of this so promptly. Let me know if there is anything
else I can help with. (Such as a particular build I can test?)

hi,
Ooops, hit the send by mistake. Please ignore the last post
The reason for this is that the OMElement.serializeAndConsume() has
been called twice
It is not supposed to be! So my guess is the NTLM authentication pat
has to call OMElement.build() first

Thanks for the update. We took a look at it (Saminda and me) and the
update you made to AbstractHttpSender is great. We will add it into
the core tree.
However we still don't understand why you are getting into the second
issue and the need to patch OMElementImpl.
Can you please give us some more information about how you are using
Axis2 and the scenario?
Thanks,
Paul

Hi Jeff,
Thank you for testing out the NTLM authentication scheme on Axis2. Will
apply the patch asap. Please be kind enough to test it out and let us
know the results.
Thank you
