Query Database through XML-SOAP

[jleon]

Im testing the XML SOAP with a simple SQL Query, however Im not sure if Im using the correct syntax because i cant see the data and the software prompt some errors.

The software used is SOAPUI 5.6

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:scx6="http://serck-controls.com/webservices/SCX6/">
<soapenv:Header/>
<soapenv:Body>
<scx6:ExecuteQuery>
<scx6:SQL>SELECT TOP(5) FULLNAME FROM CDBPOINT</scx6:SQL>

</scx6:ExecuteQuery>
</soapenv:Body>
</soapenv:Envelope>

The connection configured is http://localhost:85/webservices/scx

I think your endpoint URL is wrong.

http://localhost:85/webservices/scx

I think this should most likely just be:

http://localhost/webservices/scx

IIF you allow insecure HTTP... otherwise you could go with https://localhost/webservices/scx

The reason I think 85 is wrong is that if you installed the 'new' (old) IIS-based WebX then it will also install itself at port 85, and this will conflict with your ClearSCADA WebX which defaults to port 80, but which you say you have configured as port 85.

Hello bevan

I changed the port for webX to 80 and checked the option for insecure http from the server configuration, but the software still prompt errors.

Could be the syntax?

I'd recommend that you start with something a bit more structured before you go hand creating the SOAP requests

https://tprojects.schneider-electric.com/telemetry/display/public/CS/Using+SOAP+interface+to+connect...

I believe that you could even directly import in the Web Service references if you're using a recent version of Visual Studio, and your Visual Studio environment has access to the ClearSCADA (or Geo SCADA Expert) server.

Then once you have something working, you could use wireshark or similar to snoop on the traffic to get the structure of the requests / responses.

I think you should also go back to first principles with your fault finding.  You say 'the software still prompts errors'... that means literally nothing.  Does this error say 'Buy a licence to use this software'??.. because if so, maybe you solve the problem by buying a licence to use the software... (SOAP UI is free-to-use software.. so I suspect it's not this, but you also clearly haven't told us either way..)

So start from the beginning, things like

• can you ping the server
• can you perform a TCP connection to the port that you think should work for this SOAP request
• can you issue the most simple SOAP request to the endpoint (perhaps even an empty request which may just respond with an HTTP 200 OK response)...
• does anything else work when trying to use SOAP UI against this same server
• have you tried any other software
• does ViewX have any issues when used to do the same server query
