Hi Joerg,The problem seems to be that the parameter value you are trying to send needs to be URL-encoded.
The workaround is to use GET for your REST service in Taverna and to manually encode the dataset_uri parameter value, i.e. add the following string as the REST service's URL template:
http://opentox.informatik.tu-muenchen.de:8080/OpenTox-dev/algorithm/kNNregression?dataset_uri=http%3a%2f%2fapps.ideaconsult.net%3a8080%2fFambit%2fFdataset%2f91010%0d%0awhere "http%3a%2f%2fapps.ideaconsult.net%3a8080%2fFambit%2fFdataset%2f91010%0d%0a" is the value you wish to pass as a parameter (i.e. http://apps.ideaconsult.net:8080/Fambit/Fdataset/91010) but URL-encoded.
In Taverna 2.3, there will be an option to tick for users to say whether they want their parameters encoded or not.
For some reason, the POST option does not work even with the parameter url-encoded. We will investigate it - thank you for reporting this issue.
I am attaching the workflow (for Taverna 2.2) for you to have a look at. Regards, Alex On 31/01/2011 13:45, Joerg Wicker wrote:
Hi everyone, I am trying to access a REST webservice with the REST plugin. I want to do a simple POST. With curl, I do curl --data-urlencode -X POST http://opentox.informatik.tu-muenchen.de:8080/OpenTox-dev/algorithm/kNNregression?dataset_uri=http://apps.ideaconsult.net:8080/Fambit/Fdataset/91010 or curl -X POST http://opentox.informatik.tu-muenchen.de:8080/OpenTox-dev/algorithm/kNNregression -d "dataset_uri=http://apps.ideaconsult.net:8080/ambit2/dataset/91010"; And it works as expected. When I try to do the same with the REST plugin in Taverna, using http://opentox.informatik.tu-muenchen.de:8080/OpenTox-dev/algorithm/kNNregression?dataset_uri={dataset} as URL template, I get a 500 response from the server. (I would expect a 400 as another parameter is still missing in the call). Looking through the logs, I can see that the dataset_uri parameter is not send to the server correctly. It occurs in the logs but is not interpreted as a parameter. I get the same results when using curl without the "--data-urlencode" option. Can I send the parameters like this in a POST in Taverna? Or is there another way to send them? Thanks for any help, Joerg -- Dipl.-Bioinf.
