[Geoserver-users] application schema error

Hristo_Dechev · April 8, 2013, 9:14pm

Hi,
I’m trying to repeat the application schema tutorial example and made the
following simple steps:
- Installed geoserver 2.3.0 on Windows 7 (64), JRE 6 (64)
- Copied jar files into WEB-INF/lib
- Copied geoserver-2.3.0-app-schema-plugin/tutorial as data_dir.
Then … logging with admin or root user…
In Layer preview I can see only gsml:Mappedfeature. When I tried to get GML
from layer preview page the result is:

<ServiceExceptionReport xmlns="http://www.opengis.net/ogc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
version="1.2.0"xsi:schemaLocation="http://www.opengis.net/ogc
http://schemas.opengis.net/wfs/1.0.0/OGC-exception.xsd">
<ServiceException>
java.lang.ClassCastException:

org.opengis.feature.simple.SimpleFeatureType
org.geotools.feature.type.ComplexFeatureTypeImpl cannot be cast to
org.opengis.feature.simple.SimpleFeatureType
</ServiceException>
</ServiceExceptionReport>

Also it’s impossible to republish some other complex feature, for example if
I tried to publish again tut_RoadSegment, the error is:

java.lang.RuntimeException: Error occurred while building the resources for
the configuration page

org.geoserver.web.data.layer.NewLayerPage.buildLayerInfo(NewLayerPage.java:3

         ………………………….

Can anybody help me?

Hristo,

app-schema does not support the GeoServer web interface. Do not use the web interface to view or modify app-schema layers. The demo layer request fails because it defaults to WFS 1.0.0 / GML 2, which is also not supported by app-schema, which only supports WFS 1.1.0 and (some of) WFS 2.0.0. The WFS 1.0.0 implementation does not support complex features.

Did you try accessing the two layers using the links as the end of the tutorial?
http://docs.geoserver.org/latest/en/user/data/app-schema/tutorial.html

Namely:
http://localhost:8080/geoserver/wfs?request=GetFeature&version=1.1.0&typeName=gsml:GeologicUnit
http://localhost:8080/geoserver/wfs?request=GetFeature&version=1.1.0&typeName=gsml:MappedFeature

If you use the demo requests page, you *must* select GML 3.1 output, because these are GML 3.1 layers. (Yes, the tutorial should be updated to include this information.)

Kind regards,
Ben.

Hi,
I had the similar problem. I followed the instructions to install
Geoserver2.3.3, application schema and tutorial data on Windows 7 (64), JRE6
(32). When I enter the following url
"http://localhost:8080/geoserver/wfs?request=GetFeature&version=1.1.0&typeName=gsml:GeologicUnit",
the error message is

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

Pu Lin,

does your machine have internet access?

If you are behind a firewall that prevents outgoing web connections, GeoServer app-schema will not be able to download the GML application schemas that define the GeoSciML information model, and data store initialisation will fail. This download only occurs the first time GeoServer app-schema starts; schemas are cached for future use in the folder app-schema-cache in your data directory.

There are several solutions to this problem, documented at the end of this page:
http://docs.geoserver.org/latest/en/user/data/app-schema/app-schema-resolution.html

Also, if you are able to make outgoing HTTP requests on port 80 using a web proxy, you should also be able to configure your JRE to use this proxy. I have not tried it as I do not use Windows, but here is the Java support page:
http://www.java.com/en/download/help/proxy_setup.xml

Kind regards,
Ben.

[Please keep discussions on-list]

Pu,

are your schemas in paths relative to the schemas/catalog.xml? Such as data_dir/schemas/cgiutilities/ ? Does GeoServer still complain about geosciml.org on startup?

I think you are missing several rewrite rules; I recommend one per host so I count four. According the contents of my app-schema-cache for the tutorial, the full list of dependencies is:

Hi Ben,

I used the OASIS catalog but still got the error message. Did I miss something?

1 Add the element <catalog>../../../schemas/catalog.xml</catalog> to gsml_GeologicUnit.xml.
2. Add schemas under data_dir.
3. catalog.xml
<?xml version="1.0"?>

Off-by-one: it is only three. I have attached a corresponding catalog.xml; store your schemas under data_dir/schemas. Once you have your schemas in this tree form, you could even put them in data_dir/app-schema_cache and GeoServer will find them there.
