Nullpointer in batch job start up

[qwerts]

I am migrating from 1.0 to 2.0.

The following is the configuration:

	<bean id="demoJob" parent="simpleBatchJob">
		<property name="name" value="demoJob" />
		<property name="steps">
			<list>
				<ref bean="demoStep" />
			</list>
		</property>
	</bean>

	<bean id="demoStep" parent="taskletStep">
		<property name="tasklet" ref="tasklet" />
		<property name="jobRepository" ref="jobRepository" />
		<property name="transactionManager" ref="batchExecTransactionManager"></property>
	</bean>

	<bean id="tasklet" class="batch.demo.MyTasklet" />
		<property name="location" value="/tmp/demo/"></property>
	</bean>

On executing this piece, I get the following exception.

java.lang.NullPointerException
at org.springframework.batch.core.job.AbstractJob.upd ateStatus(AbstractJob.java:423)
at org.springframework.batch.core.job.AbstractJob.exe cute(AbstractJob.java:245)
....
....
....

Any takes on what I might be doing wrong?

Maybe your tasklet is returning null?

My tasklet returns RepeatStatus.FINISHED from its 'doExecute' method.

Tasklet doesn't have a doExecute method. You have a base class that wraps this method?
