Help with Spring Batch (Newbie)

[Jehan Jaleel]

Hi all,

I have a simple Spring Batch job where I want one Spring bean called "oracleLoader" to load some data and another bean called "oracleWriter" to write that data. Here is the spring configuration XML file for it...

 <bean id="jobRepository"
		class="org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean">
		<property name="transactionManager" ref="transactionManager" />
	</bean>

	<bean id="jobLauncher"
		class="org.springframework.batch.core.launch.support.SimpleJobLauncher">
		<property name="jobRepository" ref="jobRepository" />
	</bean> 

  <bean id="oracleWriter" class="com.mycompay.interstream.loaders.OracleARWriter">
		<constructor-arg ref="dataSource" />
	</bean>

<bean id="oracleLoader" class="com.westernunion.interstream.mycompany.OracleARLoader">
		<property name="resource" value="file:C:\data\SpringPOC\oracleAR.csv" />
		<property name="linesToSkip" value="0" />
		<property name="lineMapper">
			<bean class="org.springframework.batch.item.file.mapping.DefaultLineMapper">
				<property name="lineTokenizer">
					<bean
						class="org.springframework.batch.item.file.transform.DelimitedLineTokenizer">
						<property name="names"
							value="accountNumber,cashCode,adviceNumber,componentCode,currency,adviceDate,dueDate,amount" />
					</bean>

				</property>
				<property name="fieldSetMapper">
					<bean class="com.manning.sbia.ch01.batch.ProductFieldSetMapper" />
				</property>
			</bean>
		</property>
	</bean>

   <batch:job id="loadData">
		<batch:step id="loadDataStep">
			<batch:tasklet>
				<batch:chunk reader="oracleLoader" writer="oracleWriter" commit-interval="100" />
			</batch:tasklet>
		</batch:step>
	</batch:job> 

And here is the code from my Junit...

ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("/Interstream.xml");
                
    	  JobLauncher launcher = (JobLauncher ) applicationContext.getBean("jobLauncher");
    	  Job job = (Job)applicationContext.getBean("loadData");

Right now this is failing with the error....

org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [Interstream.xml]; nested exception is java.lang.IllegalArgumentException: 'beanName' must not be empty
	at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:412)
	at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:334)

I am guessing this is because of the

 <batch:job id="loadData">
		<batch:step id="loadDataStep">
			<batch:tasklet>
				<batch:chunk reader="oracleLoader" writer="oracleWriter" commit-interval="100" />
			</batch:tasklet>
		</batch:step>
	</batch:job>

in my configuration file, but I am at a loss how to fix it. Is there a different way I should be defining my batch job.

Thanks for any help.

One of the tags you are using is looking for the attribute called beanName to be set, but you aren't setting it. So the xml parser is throwing an exception saying your xml is not passing validation. Which tag has the beanName attribute? then set it to some value.
