Dozer-Mapping.xml: Cannot find the declaration of element 'mappings'

Question

I am trying to implement Dozer mapper in my Spring Web Service Project. I am getting below error: EXCEPTION:

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from relative location [dozer-mapping.xml] Offending resource: class path resource [projectName/application-context.xml]; nested exception is org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 4 in XML document from class path resource [folderName/dozer-mapping.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'mappings'. Caused by: org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 4 in XML document from class path resource [employeeelectionrs/dozer-mapping.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'mappings'. at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:396) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:334) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:302)

My Code: Dozer-mapping.xml

<?xml version="1.0" encoding="UTF-8"?>
<mappings xmlns:ns="http://dozer.sourceforge.net"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://dozer.sourceforge.net
http://dozer.sourceforge.net/schema/beanmapping.xsd">
 <mapping>
<class-a>org.testing.ui.types.HistoryRequest</class-a>
<class-b>org.testing.api.types.HistoryReq</class-b>
<field>
    <a>Status</a>
    <b>StatusCode</b>
</field>
</mapping>
</mappings>

application-context.xml

<import resource="dozer-mapping.xml"/>  
<bean id="dozerBeanMapper" class="org.dozer.spring.DozerBeanMapper">
    <property name="mappingFiles">
        <list>
            <value>dozer-mapping.xml</value>
        </list>
    </property>
</bean> 

Dozer Jars Used: - commons-beanutils-1.8.3.jar - commons-lang-2.6.jar - dozer-5.3.2.jar - jcl-over-slf4j-1.6.6.jar - log4j-1.2.15.jar - slf4j-api-1.6.6.jar - slf4j-log4j12-1.6.6.jar

I have got above jars from the Dozer official web page. I have tried n number of times but whenever i am starting my Weblogic server, the above said exception is been thrown. Kindly help/guide.

Answer 1

Remove the line with <import resource .. />. Why should the mapping configuration be loaded as part of the spring configuration file. The only bean interested in this configuration should be the DozerbeanMapper.

<bean id="dozerBeanMapper" class="org.dozer.spring.DozerBeanMapper">
    <property name="mappingFiles">
        <list>
            <value>dozer-mapping.xml</value>
        </list>
    </property>
</bean>
