Inherit from LV Web Service

[GregFreeman]

I have a created a Child Web Service class that inherits from Web Service. In my Web Service startup VI I am unable to use my class, because if I put it on the connector pane in the place of the Web Service.lvclass that is there by default, I get error −67001: LabVIEW Web Services: The Web service is undefined. This tells me the class object isn't being set correctly even though it's on the connector pane.

Can I do what I want? It would seem kind of silly if we are able to inherit from Web Service but then not use the child class in place of the parent on the Startup VI.

Hi Greg,

Can you provide a little more detail about your use case? Why do you want to inherit from Web Service.lvclass? Is there a reason why Web Service.lvclass does not meet your needs? I only ask because I have not found anyone else that has reported this error so I can find no information about it.

I tried to do something similar to what I thought you were doing and are not getting error -67001:

Can you provide any code that shows this behavior? Where do you get this error? When you start the web service? If it inherits, I would imagine it should work as you want since it has all the necessary methods/data that LabVIEW would need, but I'm not 100% certain.

Did you deploy and run the web service? This is a runtime, not compile time, error.

Hi Greg,

I did deploy and run it. Can you provide a snippet?

Best Regards,

I will this weekend; this has kind of taken a back seat just because I got it working without inheritance. Thanks for your responses.
