problem in handling nested exception while parsing XML.

[krish3085]

hi,
i'm running a job to read xml file .when bad record occurs during validation against xsd,job stop's execution.
i need to continue my job and want to write all bad records in separate file.

here's my code..

<batch:job id="simpleJob" job-repository="jobRepository">
<batch:step id="step1">
<batch:tasklet>
<batch:chunk reader="itemReader" writer="Writer"
commit-interval="500"/>
<batch:no-rollback-exception-classes>
org.springframework.oxm.jaxb.JaxbUnmarshallingFail ureException
</batch:no-rollback-exception-classes>

</batch:tasklet>
</batch:step>
</batch:job>

<bean id="inputFile" class="org.springframework.core.io.ClassPathResour ce" scope="step">
<constructor-arg value="com/batch/todb/NHA_Repurchase.xml"/>
</bean>

<bean id="itemReader" class="org.springframework.batch.item.xml.StaxEven tItemReader" scope="step">
<property name="fragmentRootElementName" value="ExposureData" />
<property name="resource" ref="inputFile" />
<property name="unmarshaller" ref="unMarshaller" />
<property name="strict" value="true"/>
</bean>

<bean id="unMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshalle r" scope="step">
<property name="classesToBeBound">
<value>relationalMapping.ExpData</value>
</property>
<property name="schema" value="classpath:com/batch/todb/Exp_Data.xsd"/>
</bean>

<bean id="Writer" class="com.batch.todb.XmlFileWriter" scope="step">
<property name="dataSource" ref="dataSource" />
<property name="sessionFactory" ref="sessionFactory" />
</bean>

can you say me how to continue the job and skip parse exceptions and JaxbUnmarshallingExceptions.

thanks,
gokul
