WebServices labview 2009 -> <Response/>

[PedroTeixeira1985]

Hello, i build a web service as http://zone.ni.com/reference/en-XX/help/371361E-01/lvhowto/web_service_ex/ that get the sum of two values. When i call:

http://localhost/mywebservice/add/2/3

the response of XML is: "<Response/>" and not a valid XML with the sum.

Why?

Hello, in atachment my project. When i run this WS in browser i get:

 

But when i run WS that i get from http://zone.ni.com/devzone/cda/tut/p/id/7350 it works:

I don´t understand...

Any idea?

Anyone?

Hi, all you need to do is connect the controls and the indicators at the connector pane in the original application. The same way you do while calling a subVI.

Hope this helps.

Hello Sreedhar T, thanks for reply but i don´t understand you because a i don´t call a sub VI and my VI is equal as the VI example of NI that works.

Can you take in my project (last post with attachment) and explain this?

Thanks.

Hi,

I solved the problem mapping A, B and Z with that says "Important":

Now, Web Service works!

Thanks for last replies and NI support!

Hi, Im glad you understood.

How do you deal with it when you have arrays of such input and output ?

I have the same problem. But I use the Write Response.vi, and get a blank response, as mentioned earlier. I'm surprised, because I have used this approach, I used the Flex + LabVIEW.

Hello Selentium,

I think that you need map the response in the right square. Your example don´t have anithing maps in right...

In my example i had 2 left squares (two numbers) and 1 right square (the sum).

Good luck.

I used the same approach as in the example from NI. And I have already created a similar application, but this time I have returned an empty response. And I can not find a solution to this problem.
