I promised to write some posts about how to connect to NAV Web Services from various other programming languages/platforms and I guess it is about time I kept my promise.
I will create a couple of posts on how to connect to NAV Web Services from:
For all these I will create some code that:
Here is an example of the output of the PHP web site:
Note, that the code is not necessarily perfect PHP or Java code and the intention is not to teach people how to code in these languages (I would be a bad teacher) but more to overcome some of the obstacles when trying to work with NAV.
The very first obstacle is authentication. As you probably know, NAV 2009 only supported SPNEGO (Negotiate) authentication and both PHP and Java doesn’t currently have any support natively for that.
In NAV 2009 SP1 we added a key in the Service Tier configuration file called WebServicesUseNTLMAuthentication. If you set this key to true the Web Services listener will only use NTLM authentication and as such be easier accessible from other systems.
The config file you need to modify is placed in the directory where the Service Tier executable is and is called CustomSettings.config. The section you are looking for is:
<!-- Turns on or off NTLM authentication protocol for Web Services false: Use SPNEGO (recommended) true: Use NTLM only --> <add key="WebServicesUseNTLMAuthentication" value="true"></add>
Note that .net works with both values of this settings.
