Metro client hangs when calling WCF webserver with wsHttpBinding - wcf

Question

I have generated a webservice client with a local wsdl using Metro 1.2 this way:
./wsimport.sh -extension -verbose -wsdllocation service.wsdl -s src -d target service.wsdl -Xendorsed
The wsdl uses SOAP 1.2 and wsHttpBinding. It's supposed to connect to a WCF server that's using NTLM as authentication method.
I have created an Authenticator to handle the NTLM authentication:
public class NtlmAuthenticator extends Authenticator
{
private String username = "";
private String password = "";
public NtlmAuthenticator(String username, String password) {
this.username = username;
this.password = password;
}
#Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password.toCharArray());
}
}
Which I set before each webservice method is called:
#WebEndpoint(name = "WSHttpBinding_ICustomerService")
public ICustomerService getWSHttpBindingICustomerService() {
ICustomerService service =
super.getPort(new QName("http://xmlns.example.com/services/Customer",
"WSHttpBinding_ICustomerService"), ICustomerService.class);
NtlmAuthenticator auth = new NtlmAuthenticator(username, password);
Authenticator.setDefault(auth);
return service;
}
If I use the wrong username/password, I get a 401 Unauthorized back, which is well and all, but when I use the correct username/password, the call hangs and I never get a response!
The request looks like this (captured it with netcat, so host is different, and no https):
POST / HTTP/1.1
Content-type: application/soap+xml;charset="utf-8";action="http://xmlns.example.com/services/ICustomerService/GetCustomer"
Password: [password]
Authorization: Basic [auth]
Username: [username]
Accept: application/soap+xml, multipart/related, text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
User-Agent: JAX-WS RI 2.1.7-b01-
Cache-Control: no-cache
Pragma: no-cache
Host: localhost:5500
Connection: keep-alive
Content-Length: 603
[xml follows]
I have also tried with wget 1.12 (heard that 1.11 had problem with NTLM), but it too never yields a response, just waits.
[...]
---request end---
[writing POST file customerRequest.xml ... done]
HTTP request sent, awaiting response...
I've seen that others have gotten this behaviour before, but I have not been able to find out why. Can anyone shed some light on this? JDK 1.6 on linux.

Answer 1

I found that I missed a line in my generated client code that enabled Addressing and pass it to the getPort super method:
WebServiceFeature wsAddressing = new AddressingFeature(true);
ICustomerService service =
super.getPort(new QName("http://xmlns.example.com/services/Customer",
"WSHttpBinding_ICustomerService"), ICustomerService.class,
wsAddressing);
Why metro didn't generate this is beyond me. The method looked like this in the end:
#WebEndpoint(name = "WSHttpBinding_ICustomerService")
public ICustomerService getWSHttpBindingICustomerService() {
WebServiceFeature wsAddressing = new AddressingFeature(true);
ICustomerService service =
super.getPort(new QName("http://xmlns.example.com/services/Customer",
"WSHttpBinding_ICustomerService"), ICustomerService.class,
wsAddressing);
NtlmAuthenticator auth = new NtlmAuthenticator(username, password);
Authenticator.setDefault(auth);
return service;
}
This in turn added a SOAP header to the message:
<S:Header>
<To xmlns="http://www.w3.org/2005/08/addressing">https://services.example.com/CustomerService.svc</To>
<Action xmlns="http://www.w3.org/2005/08/addressing">http://xmlns.example.com/services/ICustomerService/GetCustomer</Action>
<ReplyTo xmlns="http://www.w3.org/2005/08/addressing">
