consuming webservice with java

hans51 · 2009-01-23

Hello,

i try to consume a nav2009 webservice with java.
My problem is the authentification on the Webserver, when I call the service then i get the message
"HTTP/1.1 401 Unauthorized"

When i open the WSDL over Firefox or IE6 i get a blank Page.
I've try to debug it with FireBug and i have the same Error (401 Unauthorized).

It works only correct with IE7 and C#.

I found nothing in the MSDN or NAVdocumentation aboute the Authentification on the Webserver.

Does any body know how the Authentification works?
Use Microsoft NTLMv2 for Authentification?
Is it possible to config the Webserver Authentification?

regards
Hans51

The WebServices are usig WIndows Authentication to authenticate the user. It means that the account used for connectig must have permissions in NAV. In VS in C# the webservice have property "UseDefaultCredentials" or "Credentials" to set the credentials which are used when connecting. May be something like this will be in the Java...

On my blog you will find a couple of samples on how to access web services from Javascript - it isn't exactly what you are looking for - but it shows how to access WS from something different than C# (where the add web reference tends to help you a lot).

Yes i have Credentials in Java and i have try any auth.-methods to connect to the webserver.
I get every time the error message:

HTTP/1.1 401 Unauthorized
Content-Length: 0
Server: Microsoft-HTTPAPI/1.0
WWW-Authenticate: Negotiate

The Problem is not the Webservice, i can create the Stubs proper.
The best way is to diable the Authentification, my Server is in a DMZ.
Is it possible to use a IIS/Tomcat to publish the Webservices, or disable the Auth. by the configfile of NAV Webserver?

I'm in a similar situation (I have a client trying to use Java to consume NAV 2009 web services, I know next to nothing about Java personally) and am currently working through it with Microsoft support. Their advice so far is to provide an example here...

http://java.sun.com/javase/6/docs/techn ... -auth.html

And utter the cryptic phrase "Where our implementation is using Http SPNEGO Negotiate".

Best of luck, please post an update here if you get any further!

Hello. In order to see the webservice in Firefox, you need to follow the following direction

Out of the box the Firefox negotiate authentication is disabeled, to make it work you have to configure your Firefox Browser to use the negotiate authentication first.

1. Start firefox, enter about:config to the address field.
2. choose the network.negotiate-auth.trusted-uris parameter, set this value to the domain or machine name you want to activate Negotiate for.

}

just shoot in the dark but have you tried

httpconn.setRequestProperty("Authorization", "Negotiate " + encoding);
httpconn.setRequestProperty("Proxy-Authorization", "Negotiate " + encoding);

Also have you looked at this solution

import microsoft_dynamics_schemas.LettersLocator;
import microsoft_dynamics_schemas.Letters_Port;
import sun.security.krb5.internal.Authenticator;

in to eclipse ide
iam using same code given in mysourcecode example.
