Description

Hi
i have used castor maven plugin 2.0-alpha1 to generate the classes for the xsd. Using the generated classes i have generated mapping file from mapping tool.
In my xsd...
<xs:complexType name="AffiliationType">
<xs:sequence>
<xs:element name="Name" type="xs:string" minOccurs="0"/>
<xs:element name="Description" type="xs:string" minOccurs="0"/>
<xs:element name="Relationship" type="xs:string" minOccurs="0"/>
<xs:element name="AffiliationType" type="xs:string" minOccurs="0" maxOccurs="unbounded"/>
<xs:choice maxOccurs="unbounded">
<xs:element name="RetailStoreID" type="xs:string"/>
<xs:element name="PartyID" type="xs:string"/>
<xs:element name="CustomerID" type="xs:string"/>
</xs:choice>
</xs:sequence>
<xs:attribute name="Action" type="AffiliationActionType"/>
<xs:attribute name="UpdateType" type="CustomerUpdateType" use="optional" default="Existing"/>
<xs:attribute name="PrimaryFlag" type="xs:boolean" use="optional" default="true"/>
</xs:complexType>

the classes with respect to nested choice are generated properly. But in the mapping file for the corresponding element (AffiliationTypeChoice) "error-if-this-is-used" is mapped.

<bind-xml name="AffiliationType" node="element"/>
<field name="affiliationTypeChoice" type="com.wsgc.blueprint.phase0.prototype.atp.schema.AffiliationTypeChoice" required="true"><bind-xml name<b>="error-if-this-is-used" </b>node="element"/>
</field></class>

i have attached mapping file and xsd for your refernce.

need ur help soon

thanks in advance

Why are you using a mapping file at all when you generate classes with the Castor source generator ?

without mapping file , marshalling works but not unmarshalling.
while unmarshalling, it searches for the corresponding class for root of the xml. If mapping file is not provided it raises an exception.
That's the reason for me to use mapping file

That's - in my humble opinion - a complete mis-usage of Castor. Can you show me how you are using the Unmarshaller (in code), and what kind of exception are you getting ?

WHen you generate classes from an XML schema, Castor - in addition to the Java entity classes - will generate descriptor classes. These classes carry all the information to map between XML artifacts and Java classes, incl. namespaces, names, etc.

Question: are you using Castor for the first time, or have you been using Castor for e.g. months and are you facing a particular problem ? If you happen to be a first time user, please do consider subscribing to e.g. the user mailing list, and have a look at the archives as well.

As explained above, generating classes from an XML schema and using a mapping file at the same time just ... well, does not make any sense.

I have a issue same as described in first comment for the tag the maping.xml file generated from MappingTool.java has generated some
"error-if-this-is-used" strings for the xs:choice tags.

appreciate your help in knowing solution / workaround on this.

I have resolved this Issue by using the Castor Generated Descriptor Files along with using mapping.xml.

1) Use mapping.xml in the spring bean defination as follows.

<bean id="castorMarshaller" class="org.springframework.oxm.castor.CastorMarshaller" >
<property name="mappingLocation" value="/WEB-INF/mapping.xml" />
</bean>

2) mapping.xml should define only root element. (else root element not found error.)

<class name="com.comp.ws.edc.schema.beans.EdcServiceRequest">
<description xmlns="">Default mapping for class
com.comp.ws.edc.schema.beans.EdcServiceRequest</description>
<map-to xml="edcServiceRequest" ns-uri="http://www.comp.com/edc/schema/beans" />
<field name="data" type="com.comp.ws.edc.schema.beans.Data"
required="true">
<bind-xml name="data" node="element" />
</field>
</class>

3) Place all Castor generated Descriptor files (for all the leaf nodes elements) on classpath marshaller will auto pick these definition from the generated descriptor class.
