schema name conflict in collection???

[kmbarlow]

Hiyas,

Can anyone offer some guidance as to what this error means:

org.springframework.xml.xsd.commons.CommonsXsdSchemaException: Schema [ServletContext resource [/WEB-INF/xsd/schema1.xsd]] could not be loaded; nested exception is org.apache.ws.commons.schema.XmlSchemaException: Schema name conflict in collection. Namespace: urn:com.company.domain.values

I used JAXB (jdk 1.6) to generate the schema for my java classes (schemagen). Here is the Spring WS configuration:

	<bean id="profilerEndpoint" class="com.company.aggregate.profile.device.ProfilerImpl" />
	
	<bean class="org.springframework.ws.server.endpoint.adapter.GenericMarshallingMethodEndpointAdapter">
		<constructor-arg ref="marshaller" />
	</bean>
	
	<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
		<property name="classesToBeBound">
			<list>
				<value>com.company.aggregate.profile.device.Profile</value>
				<value>com.company.aggregate.profile.device.Duplication</value>
				<value>com.company.aggregate.profile.device.Association</value>
				<value>com.company.aggregate.profile.device.DeviceEntry</value>
			</list>
		</property>
		<property name="schema" value="/WEB-INF/xsd/schema.xsd" />
	</bean>
		
	<bean id="profileDevice" class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition">
		<property name="schema" ref="schema" />
		<property name="portTypeName" value="ProfileDevice" />
		<property name="locationUri" value="/services/" />
		<property name="targetNamespace" value="http://www.company.com/information/services" />
	</bean>
	
	<bean id="schema" class="org.springframework.xml.xsd.commons.CommonsXsdSchemaCollection">
		<property name="xsds">
			<list>
				<value>/WEB-INF/xsd/schema.xsd</value>
				<value>/WEB-INF/xsd/schema1.xsd</value>
				<value>/WEB-INF/xsd/schema2.xsd</value>
				<value>/WEB-INF/xsd/schema3.xsd</value>
				<value>/WEB-INF/xsd/schema4.xsd</value>
				<value>/WEB-INF/xsd/schema5.xsd</value>
			</list>
		</property>
		<property name="inline" value="true" />
	</bean>

Thanks.

For anyone else having trouble with this error... make sure the XSDs are listed in order of increasing dependencies...

for example, if schema2.xsd imports schema1.xsd, schema1.xsd must be appear 1st in the list. This applies all the way up the chain...

A little note however, if you just list the highest level schema - the one that imports all the rest, you do not technically need to declare all the others, though it may be clearer to anyone reading the code.

Thanks for this helpful post, it solved my problem. It would be great if this information was added to the javadoc for CommonsXsdSchemaCollection!

Hi,
In my case org.springframework.xml.xsd.commons.CommonsXsdSche maCollection throwing the following exception. What are all the specific jars I have to include to use CommonsXsdSchemaCollection?

org.springframework.web.servlet.FrameworkServlet initServletBean Context initialization failed
