Hi Igor, I assumed you have been through the tutorial?
http://docs.geoserver.org/2.0-RC2/user/data/app-schema/tutorial.html There is a working example inside. What errors are you receiving? -----Original Message----- Hi everyone: First of all, I must apologize for my english. I've been several days trying to fetch some data (WFS getFeature) from a database table that references a second table. The first table is STOP which has some properties (code, name, description...) and among those properties, there is one (PROVIDER_ID) that references another table called PROVIDER: a PROVIDER has many STOPs and one STOP belongs to only one PROVIDER. What I'm trying to do is to fetch STOP's data and the PROVIDER's data for each STOP. These are the files I have created for this sample: * datastore.xml contains: <dataStore> <id>transitstop_datastore</id> <name>transitstop_datastore</name> <enabled>true</enabled> <workspace> <id>WorkspaceInfoImpl-7093984a:13a7476a0f3:-8000</id> </workspace> <connectionParameters> <entry key="namespace">http://telvent.com/cocities</entry> <entry key="dbtype">app-schema</entry> <entry key="url">file:workspaces/cocities/transitstop/transitstopMapping.xml</entry> </connectionParameters> </dataStore> * TransitStop.xsd <?xml version="1.0" encoding="UTF-8"?> <xs:schema targetNamespace="http://telvent.com/cocities"; xmlns:cocities="http://telvent.com/cocities"; xmlns:gml="http://www.opengis.net/gml"; xmlns:xs="http://www.w3.org/2001/XMLSchema"; elementFormDefault="qualified" attributeFormDefault="unqualified" version="1.0"> <xs:import namespace="http://www.opengis.net/gml"; schemaLocation="http://schemas.opengis.net/gml/3.1.1/base/feature.xsd"; /> <xs:element name="TransitStop" type="cocities:TransitStopType" /> <xs:complexType name="TransitStopType"> <xs:complexContent> <xs:extension base="gml:AbstractFeatureType"> <xs:sequence> <xs:element name="code" type="xs:string" /> <xs:element name="name" type="xs:string" /> <xs:element name="long_name" type="xs:string" /> <xs:element name="bus_stop" type="gml:PointPropertyType" /> <xs:element ref="cocities:provider" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> <xs:element name="provider" type="cocities:ProviderType" /> <xs:complexType name="ProviderType"> <xs:complexContent> <xs:extension base="gml:AbstractFeatureType"> <xs:sequence> <xs:element name="name" type="xs:string" maxOccurs="unbounded" /> <xs:element name="id" type="xs:string" maxOccurs="unbounded" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> </xs:schema> * transitstopMapping.xml contains: <?xml version="1.0" encoding="UTF-8"?> <as:AppSchemaDataAccess xmlns:as="http://www.geotools.org/app-schema"; xmlns:ogc="http://www.opengis.net/ogc"; xmlns:xs="http://www.w3.org/2001/XMLSchema"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.geotools.org/app-schema AppSchemaDataAccess.xsd"> <namespaces> <Namespace> ... </Namespace> </namespaces> <sourceDataStores> <DataStore> <id>cocitiesds</id> ... </DataStore> </sourceDataStores> <targetTypes> <FeatureType> <schemaUri>TransitStop.xsd</schemaUri> </FeatureType> </targetTypes> <typeMappings> <FeatureTypeMapping> <sourceDataStore>cocitiesds</sourceDataStore> <sourceType>stop</sourceType> <targetElement>cocities:TransitStop</targetElement> <attributeMappings> <AttributeMapping> <targetAttribute> cocities:TransitStop </targetAttribute> </AttributeMapping> <AttributeMapping> <targetAttribute>cocities:TransitStop</targetAttribute> <idExpression> <OCQL>getId()</OCQL> </idExpression> </AttributeMapping> ... ... ... <AttributeMapping> <targetAttribute>cocities:provider</targetAttribute> <sourceExpression> <OCQL>provider_id</OCQL> </sourceExpression> </AttributeMapping> </attributeMappings> </FeatureTypeMapping> <FeatureTypeMapping> <targetElement>cocities:provider</targetElement> <sourceDataStore>cocitiesds</sourceDataStore> <sourceType>provider</sourceType> <attributeMappings> <AttributeMapping> <targetAttribute> cocities:provider </targetAttribute> <idExpression> <OCQL>getId()</OCQL> </idExpression> </AttributeMapping> <AttributeMapping> <targetAttribute>cocities:name</targetAttribute> <sourceExpression> <OCQL>name</OCQL> </sourceExpression> </AttributeMapping> </attributeMappings> </FeatureTypeMapping> </typeMappings> </as:AppSchemaDataAccess> I've been testing thousands of different configurations and I'm not capable of making it work ¿Does anyone know about a working example that makes the same thing I'm looking for?
