[Geoserver-devel] prefix null with app schema

alessandro_marrone1 · January 31, 2012, 2:10pm

Hello

I was trying to configure an app-schema to deliver WOML features.
I’m able to deliver WFS with womlcore and womlswo elements, but when I try to map some GML elements I get the following result:

<ows:ExceptionReport version=“2.0.0” xsi:schemaLocation=“http://www.opengis.net/ows/1.1 http://localhost:8080/geoserver/schemas/ows/1.1.0/owsAll.xsd”>
<ows:Exception exceptionCode=“NoApplicableCode”>
ows:ExceptionTextjava.io.IOException: The prefix "null" for element "null:name" is not bound.
The prefix "null" for element "null:name" is not bound.
The prefix "null" for element "null:name" is not bound.
</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>

I’m using Geoserver 2.2 SNAPSHOT

This is the mapping file:

<?xml version="1.0" encoding="UTF-8"?>

<as:AppSchemaDataAccess xmlns:as=“http://www.geotools.org/app-schema”
xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance”
xsi:schemaLocation=“http://www.geotools.org/app-schema AppSchemaDataAccess.xsd”>

Alessando,

your mapping file is schema-invalid. targetTypes should contain only one FeatureType which can contain multiple schemaUri elements. (At this point a nonvalidating parser is used; I'm not sure if it ignores the second FeatureType.)

Kind regards,
Ben.
