Webservice client - chemspider

KNIME Analytics Platform
1

Hi All,

I'm trying to access chemspider through the generic webservice client. For chemspider you need a security token. Would this mean that it's not possible to access it in this way or can the token be included in the "add SOAP header".

Anyway, I was not able to find and/or analyse and of the wsdl file from chemspider so far. Any input is appreciated.

Thanks,

Peter

Which ChemSpider web service are you using? For example for the Search webservices (http://www.chemspider.com/Search.asmx) the WSDL can be found at http://www.chemspider.com/Search.asmx?WSDL.

Hi Aileen,

If I try the services mentioned by you and press analyze I get the error message:

<no message> (UndeclaredThrowableException)

It will not return any Operations (methods).

I understand the service needs a token, which we have, but I'm not sure how to implement this token within this web-service node. Could this also be the reason knime doesn't find the operations?

Thanks,

Peter

Hello Peter,

I've had a play to get a ChemSpider webservice working from Knime and have documented how I got it working here: http://www.chemspider.com/blog/how-to-use-chemspider-webservices-from-knime.html - hope that's useful and gets you started to do likewise...

Let me know if you have any further problems.

Regards,

Aileen

Hi Alein,

Thanks a lot.

The local wsdl file solved all issues.

Cheers,

Peter
