Getting error Schema abc.xsd could not be loaded. IllegalArgumentException: The resource path def.xsd has been normalized to null which is not valid

Question

I used jaxb2-maven-plugin to generate java classes from xsd. Classes are generating. Below is sample of one of my xsd file

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    targetNamespace="http://customer.serviceoperations.lmsapi.message.webservice.lms.vu360.softech.com"
    xmlns="http://customer.serviceoperations.lmsapi.message.webservice.lms.vu360.softech.com" 
    xmlns:cust="http://customer.types.lmsapi.message.webservice.lms.vu360.softech.com"
    xmlns:tr="http://transactionresult.types.lmsapi.message.webservice.lms.vu360.softech.com"
    elementFormDefault="qualified"
    attributeFormDefault="unqualified">

    <xsd:import namespace="http://transactionresult.types.lmsapi.message.webservice.lms.vu360.softech.com" schemaLocation="../types/TransactionResultType.xsd"/>
    <xsd:import namespace="http://customer.types.lmsapi.message.webservice.lms.vu360.softech.com" schemaLocation="../types/Customer.xsd"/>

    <xsd:element name="AddCustomerRequest">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element name="Customers" type="cust:Customers" minOccurs="1" maxOccurs="1" nillable="false" />
            </xsd:sequence>
            <xsd:attribute name="key" type="xsd:string" use="required" />
            <xsd:attribute name="ResellerId" type="xsd:nonNegativeInteger" use="required" />
        </xsd:complexType>
    </xsd:element>

    <xsd:element name="AddCustomerResponse">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element name="RegisterCustomers" type="cust:RegisterCustomers" minOccurs="0" maxOccurs="1" nillable="false" />
            </xsd:sequence>
            <xsd:attribute name="transactionResult" type="tr:TransactionResultType" use="required"/>
            <xsd:attribute name="transactionResultMessage" type="xsd:string"/>
        </xsd:complexType>
    </xsd:element>

</xsd:schema>

After generating classes from xsd. I am trying to set up a spring web service. Here is my web service configuration file for spring

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
                    ...  
                    http://www.springframework.org/schema/web-services/web-services-2.2.xsd ">

    <context:component-scan base-package="pk.training.basitmahmood.webservice.endpoints.impl"/> 

    <bean id="LmsApi" class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition" lazy-init="true">  
        <property name="schemaCollection" ref="lmsApiSchema" />  
        <property name="portTypeName" value="LmsApiPortType"/>  
        <property name="serviceName" value="LmsApiServices" />  
        <property name="locationUri" value="/endpoints"/>  
    </bean> 

    <bean id="lmsApiSchema" class="org.springframework.xml.xsd.commons.CommonsXsdSchemaCollection">  
        <property name="inline" value="true" />  
        <property name="xsds">  
            <list>  
                <value>schemas/lmsapi/serviceoperations/CustomerServiceOperations.xsd</value>
                <value>schemas/lmsapi/serviceoperations/EnrollmentServiceOperations.xsd</value>
                 ...
                <value>schemas/lmsapi/types/Address.xsd</value>
                 ...
                <value>schemas/lmsapi/utility/OrgGroupUtility.xsd</value>
                <value>schemas/lmsapi/utility/utility.xsd</value>
            </list>  
        </property>  
    </bean>

</beans>

Now when I run my project I get the following error

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'lmsApiSchema' defined in ServletContext resource [/WEB-INF/spring/appServlet/webservices-context.xml]: Invocation of init method failed; nested exception is org.springframework.xml.xsd.commons.CommonsXsdSchemaException: Schema [ServletContext resource [/schemas/lmsapi/serviceoperations/CustomerServiceOperations.xsd]] could not be loaded; nested exception is java.lang.IllegalArgumentException: The resource path [/../types/TransactionResultType.xsd] has been normalized to [null] which is not valid
....
Caused by: org.springframework.xml.xsd.commons.CommonsXsdSchemaException: Schema [ServletContext resource [/schemas/lmsapi/serviceoperations/CustomerServiceOperations.xsd]] could not be loaded; nested exception is java.lang.IllegalArgumentException: The resource path [/../types/TransactionResultType.xsd] has been normalized to [null] which is not valid
...
Caused by: java.lang.IllegalArgumentException: The resource path [/../types/TransactionResultType.xsd] has been normalized to [null] which is not valid

In my CustomerServiceOperations.xsd I am using the following line

<xsd:import namespace="http://transactionresult.types.lmsapi.message.webservice.lms.vu360.softech.com" schemaLocation="../types/TransactionResultType.xsd"/>

Now schemaLocation="../types/TransactionResultType.xsd" is creating problem. Although it is right because if I click on ../types/TransactionResultType.xsd, it will open the right file. Now spring is appending / before path like [/../types/TransactionResultType.xsd]. How can i resolve this issue ?

Thanks

Set the uriResolver to defaultURIResolver

CommonsXsdSchemaCollection collection = new CommonsXsdSchemaCollection(schema);
collection.setUriResolver(new DefaultURIResolver());
