[Zoo-discuss] POST not implemented

Wed Aug 13 10:54:40 PDT 2014

Dear Pablo,
sorry for answering so late to your email.

The issue should be fixed with revision 498 [1], so I would like to invite you to try upgrading your setup and try to run the same request again then report here your result.

Please, also note that when you provide the InputPolygon using the GetFeature request then the value used will be a FeatureCollection not a FeatureMember as you used in the xml request your provided in the previous email. So, I think that you should also review your initial request.

I hope this help you to solve your problem and we will hear back from you,
Best regards,

[1] http://zoo-project.org/trac/changeset/498

> > From my point of view, there is an issue in the request you provided, you defined the mimeType attribute of your ComplexeData node to « text/xml » which is valid, but then, rather than providing a XML node in the request, you provided a CDATA node which should be used for ComplexData with the mimeType defined to application/json for instance.
