  1. PONo response of (ogc) "Sensor Observation Service" request from server
    text
    copied!<p>I am trying to make a "registerSensor" request. See the following xml file. But unfortunately i only get an exception, about an NULL GET request. What confuse me the most is the fact that i send and read by POST method.</p> <p>I know that probabely this issue doesn't fit to that forum, but i don't know where else to look for.... (would be even glad if you just give any advice, beside the ogc dokus)</p> <p>I tested it twice on my own server and also at: http: //giv-sos.uni-muenster.de: 8080/52nSOSv3/</p> <p>My request:</p> <pre><code> &lt;RegisterSensor service="SOS" version="1.0.0" xmlns="http://www.opengis.net/sos/1.0" xmlns:swe="http://www.opengis.net/swe/1.0.1" xmlns:ows="http://www.opengeospatial.net/ows" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:gml="http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc" xmlns:om="http://www.opengis.net/om/1.0" xmlns:sml="http://www.opengis.net/sensorML/1.0.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/sos/1.0" http://schemas.opengis.net/sos/1.0.0/sosRegisterSensor.xsd http://www.opengis.net/om/1.0 http://schemas.opengis.net/om/1.0.0/extensions/observationSpecialization_override.xsd&gt;
