Hi Alan, Thank you. Your advise got me one step further. By using the "Add value" button rather than "Add URL", I passed the ExcecuteProcess_r.add.Datainputs box without errors. But unfortunately, the next box, ExcecuteProcess_r.add, turned red ...
This error is something I suppose the pyWPS folks should address. Accordingly I send this message also to the pyWPS mailing list. Jorge, The error message shown in taverna was a "404 Not found" error. When I investigated the apache error.log, I found this error: script not found or unable to stat: /usr/lib/cgi-bin/wps And that was correct. I had no script with that name in the cgi-bin directory. I am not able to find any reference to this script in the cookbook. But I searched in the software, and found this in the file pywps/debian/pywps.postinst: ... ln -s /usr/bin/wps.py /usr/lib/cgi-bin/wps.py ... I found a /usr/local/bin/wps.py file, and run manually this command (without invoking the pywps.postinst script): sudo ln -s /usr/local/bin/wps.py /usr/lib/cgi-bin/wps When testing taverna again, I stopped again in the ExcecuteProcess_r.add box, but this time with a different error message: <Exception xmlns="http://www.opengis.net/ows/1.1"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; exceptionCode="NoApplicableCode"> <ExceptionText> 'The requested process is not part of the instance. Check pywps conf file and WSDL. WSDL has to point to the correct wrapper, please check location attribute in address element of WSDL document' </ExceptionText> </Exception> Any advise?
