URL not working

Neha_Marwaha

I am not able to access the web service using pages.
I am giving the URL as below:

http://t38:7047/DynamicsNAV/ws/Cronus_I ... MyCustomer

and getting the result as "page cannot be displayed"..
Kindly suggest what are the reasons behind this.

freddy.dk

a very open question - hard to know what has been checked and what not...

1. Is the Service running? (default installation leaves the Web Service Listener service as Start manually)?

2. Page and Codeunit in the URL are case sensitive - should be Page/MyCustomer - but this would give a different error I think.

3. Does http://localhost:7047/DynamicsNAV/WS/CR ... d/Services give any result?
It should list the available Services under that company - then we know that the Company Name is escaped correctly - and you should be able to copy and paste the URL from one of these services.

4. Does http://localhost:7047/DynamicsNAV/WS/Services give any result?
If this URL works and not the first - it points towards a wrong company name in the URL - what is the company name in clear text?

5. Which page number is exposed in the Web Service table as MyCustomer - and what is the page type (only Card and List can be exposed as Web Services)

One of these questions (in order of likelyhood) should bring you on the right track.

Thanx for the helpful suggestion.
I have tried the solution given by Freddy Kristiansen.
When i give the URL

http://localhost:7047/DynamicsNAV/WS/CR ... d/Services

It only shows the System services.

- <discovery xmlns="http://schemas.xmlsoap.org/disco/&quot; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&quot; xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt;
<contractRef ref="http://localhost:7047/DynamicsNAV/WS/CRONUS_India_Ltd/SystemService&quot; xmlns="http://schemas.xmlsoap.org/disco/scl/&quot; />
</discovery>

As I published a page and a codeunit..It doesnt display other services..as shown in the demo.
Kindly suggest

freddy.dk

So this means that the Computername is right, the Company name is right and Web Services Service is running - but you haven't any pages nor codeunits exposed.

Try to attach a screenshot of your Web services table (Run the table from the Classic Client - and make a screen shot)

Neha_Marwaha

I am not able to attach the screenshot here.

freddy.dk

You should have an upload attachment right underneath this field (attaching an image of that:-))

Neha_Marwaha

I tried the same but it doesnt attach...i'll try again
Thanx for your support

I am also facing the same problem.
I use URL --> http://im56:7047/DynamicsNAV/WS/Services.
I have checked all pre-requisites and they are set properly.
Not sure what is going wrong.

When i start the Microsoft Dynamics NAV Business Services, it gets started and then stopped automatically with a warning message.

Neha - could it be that the page is not actually published?

It would be interesting to see the screen shot - In the Web Services form (810) has this page been added to the table and is the Published box marked?

Tom_Cornelius

Hamant - can you provide the text of the application event log related to the service starting?

hav

The error related to starting the web service in the application event log is:
The service MicrosoftDynamicsNavWS failed to start. This could be caused by a configuration error. Detailed error information:HTTP could not register URL https://+:7047/DynamicsNAV/. Another application has already registered this URL with HTTP.SYS.

I then opened CustomSettings.config file and saw that the key 'WebServiceSSLEnabled' is set to true. I changed it to false and restarted the service. It got started.

Now when i open the URL http://im56:7047/DynamicsNAV/WS/Services in browser, it does not work.
The error it displays is not consistent. Some time it displays 'page not found error' whereas sometime it shows 'login failed when connecting to SQL Server im56'

I either case i am unable to test the webservice.

freddy.dk

Is the SQL Server running on the same machine as the servicetier/webservice listener?
You could add your customsettings.config in a code or quote here.

hav

Yes, the SQL Server is on the same machine as that of the service tier i.e.IM56

Note that i am testing a codeunit web service.

Strange

if the web service listener service is started

http://localhost:7047/DynamicsNAV/WS/Services

(that is of course if the WebServicePort is 7047, SSL is false and your instance name is DynamicsNAV)
should always return a list of what is exposed as web services
What do you have exposed as web services? (content of your web services table)

You could try to change database server to localhost instead of the computername - but else I am pretty much out of options.

hav

One mistake i found was that my Codeunit name was 'Test' and Web Service name i gave was 'Test Service'. According to the 'Walkthrough: Creating and Consuming a Codeunit Web Service' in C/SIDE Reference Guide, the Web Service name and Codeunit name is 'Letters'.

So i changed the name of my Web Service from 'Test Service' to 'Test'.

Now if i run http://localhost:7047/DynamicsNAV/WS/services, it displays below error
<discovery xmlns="http://schemas.xmlsoap.org/disco/&quot; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&quot; xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt;
<contractRef ref="http://localhost:7047/DynamicsNAV/WS/SystemService&quot; xmlns="http://schemas.xmlsoap.org/disco/scl/&quot; />
<contractRef ref="http://localhost:7047/DynamicsNAV/WS/Codeunit/Test&quot; xmlns="http://schemas.xmlsoap.org/disco/scl/&quot; />
</discovery>

Refer the attachment for snapshot of Web Service form.

So, whats going wrong is the mystery.

Tom_Cornelius

What is the error? From your post it appears as though the services were discovered successfully.

freddy.dk

<discovery xmlns="http://schemas.xmlsoap.org/disco/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<contractRef ref="http://localhost:7047/DynamicsNAV/WS/SystemService" xmlns="http://schemas.xmlsoap.org/disco/scl/" /> 
<contractRef ref="http://localhost:7047/DynamicsNAV/WS/Codeunit/Test" xmlns="http://schemas.xmlsoap.org/disco/scl/" /> 
</discovery>

If this is your error - then it is not an error!
This is how it is supposed to look - it tells you which Services are available and where to find them.
You can copy the URL for the Codeunit/Test and see the discovery for that in a browser - looking like a lot of XML too - thats web services.
In order to use a codeunit Web Service you need to specify the company name like

http://localhost:7047/DynamicsNAV/WS/CRONUS_Internaional_Ltd/Codeunit/Testbut still - IE will just show the discovery, you need something that can consume the web services like InfoPath or Visual Studio.

hav

I agree with you.

I have written a console application to consume/test the web service.
It works fine.

Thanks for your support.
