XML document structures must start and end within the same entity

[jladenfors]

Hello,

I am using Spring-batch 1.1.4 RELEASE and I have stumbled across an error while parsing a XML file with StaxEventItemReader. I have tried using different marshallers but with the same result.

My bean

 <bean id="fundCompanyReaderCastor" class="org.springframework.batch.item.xml.StaxEventItemReader">
        <property name="fragmentRootElementName" value="fundcompany" />
        <property name="resource" value="file://FundCompanies.xml" />
        <property name="fragmentDeserializer">
            <bean class="org.springframework.batch.item.xml.oxm.UnmarshallingEventReaderDeserializer">
                <constructor-arg>
                    <bean class="org.springframework.oxm.castor.CastorMarshaller">
                        <property name="targetClass" value="se.model.FundCompany"/>
                        <property name="ignoreExtraAttributes" value="true"/>
                        <property name="ignoreExtraElements" value="true"/>
                    </bean>
                </constructor-arg>
            </bean>
        </property>
    </bean>

The reader parses my XML file but on the last element the following exception is thrown. (The XML file is valid according to my XML tools)

....

Anyone else experiencing this problem? My workaround so far has been to extend StaxEventItemReader and override the the moveCursorToNextFragment method where I can deal with the exception myself and return false which lets the job continue. Not nice ... I... know...

Which version of StAX are you using (and is there maybe more than one on the classpath?). I don't recognise this issue but there have been similar problems with some providers. The reference impl, and the one in the JDK (1.6) should work.

(Please use [code][/code] tags to post code and stack traces.)

I didn't previously explicitly import any StAX dependency to my project so I can't really say which version I was using but after declaring the StAX 1.2.0 reference implementation the errors disappeared.

Thanks for pointing me in the right direction!
