SAXParseException; src-resolve: Cannot resolve the name '...' to a(n) 'type definition' component

Question

I'm trying to do schema validation, currently using a javax.xml.validation.SchemaFactory. Unfortunately When I call the newSchema(Source schema) function, I get the following error:

Caused by: org.xml.sax.SAXParseException; systemId: file:/C:/Users/C42056/Documents/workspace-sts-3.2.0.RELEASE/cec-sample-ws-integration-2-war/target/classes/WEB-INF/schemas/xsd/individual/PrivateComponentTypes_4_0.xsd; lineNumber: 33; columnNumber: 88; src-resolve: Cannot resolve the name 'utility:ObjectStatusDateType' to a(n) 'type definition' component.

The utility:ObjectStatusDateType element is used in the .xsd file which I am passing into the newSchema(Source schema) function. I am importing the ObjectStatusDateType from another .xsd file- for which I have tripple checked the file path. The utility namespace is also declared properly.

Here's a snippet of the schema I am passing into the function (LocateCoverageIndexesByIdentifier_3_0.xsd):

<xs:import namespace="http://www.sei.com/utility/1/" schemaLocation="../../utility/InvocationOutcome_1_0.xsd"/>
<xs:import namespace="http://www.sei.com/utility/1/" schemaLocation="../../utility/ObjectHistory_1_0.xsd"/>
<xs:import namespace="http://www.sei.com/individual/component/4/" schemaLocation="../PrivateComponentTypes_4_0.xsd"/>
<xs:import namespace="http://www.sei.com/individual/shared/5/" schemaLocation="../IndividualTypes_5_0.xsd"/>
.
. <!-- Some more stuff -->
.
<xs:element name="coveragePeriod" 
            type="utility:ObjectStatusDateType" 
            minOccurs="0"/>

And this is from ObjectHistory_1_0.xsd:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
           xmlns:tns="http://www.sei.com/utility/1/" 
           targetNamespace="http://www.sei.com/utility/1/" 
           elementFormDefault="qualified" 
           attributeFormDefault="unqualified" 
           version="1.0">
.
. <!-- Some more stuff -->
.
  <xs:complexType name="ObjectStatusDateType">
    <xs:sequence>
      <xs:element name="effectiveDate" type="xs:date"/>
      <xs:element name="cancelDate" type="xs:date" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>

And lastly, the bean

<bean id="locateClaimValidator" 
      class="com.sei.ec.xml.validation.SimpleXmlValidator">
  <constructor-arg>
    <value>classpath:WEB-INF/schemas/xsd/individual/ci/LocateCoverageIndexesByIdentifier_3_0.xsd
    </value>
  </constructor-arg>
</bean>

Has anybody encountered this type of issue before?

Answer 1

I've had this issue before. Everything validated in Eclipse, but broke when running. Do any of your schemas import more than one schema into the same namespace?

Something like this will not work, but will be validated by Eclipse:

<import namespace="http://www.whatever.gov" location="../wherever" />
<import namespace="http://www.whatever.gov" location="../folder/superawesomeschema.xsd" />

Answer 2

Lots of people have encountered this type of issue before. It comes up whenever your validator is, for whatever reason, not loading the schema documents you want it to load (and think it's loading).

To confirm the diagnosis: try introducing an error -- say, a well-formedness error -- into ObjectHistory_1_0.xsd, and see if the system complains.

Answer 3

Using Xerces this can solved by setting the feature http://apache.org/xml/features/honour-all-schemaLocations to true.

The feature http://apache.org/xml/features/honour-all-schemaLocations is only available from Xerces 2.7.0. Current releases of Java 5.0 and 6.0 have a Xerces 2.6.2 built-in. Hence one has to use a newer Xerces library in order for this to work, ie. copying xml-apis.jar and xercesImpl.jar to <jdk-home>/jre/lib/endorsed and creating a jaxp.properties file in <jdk-home>/jre containing the line

javax.xml.validation.SchemaFactory\:http\://www.w3.org/2001/XMLSchema=org.apache.xerces.jaxp.validation.XMLSchemaFactory
