Spring Batch: SimpleJobRepository - Example not working

I been trying to get the Spring Batch Hello World 3 example running from

http://jroller.com/0xcafebabe/entry/spring_batch_hello_world_3

I was missing some jars and someone helped me out and got the project working better but I still have a error.. can someone please help me out:

Here is my applicationContext.xml

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

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

    <bean id="jobRepository" class="org.springframework.batch.core.repository.support.SimpleJobRepository">
        <constructor-arg>
            <bean class="org.springframework.batch.core.repository.dao.MapJobInstanceDao"/>
        </constructor-arg>
        <constructor-arg>
            <bean class="org.springframework.batch.core.repository.dao.MapJobExecutionDao" />
        </constructor-arg>
        <constructor-arg>
            <bean class="org.springframework.batch.core.repository.dao.MapStepExecutionDao"/>
        </constructor-arg>
        <constructor-arg>
            <bean class="org.springframework.batch.core.repository.dao.MapExecutionContextDao"/>
        </constructor-arg>
    </bean>
</beans>

This is the error I am getting on the console

Looks like the API of SimpleJobRepository has changed between 1.1.2 and 1.1.3 (bad moment to introduce backward incompatible change IMHO).

The tutorial you are following uses Spring Batch 1.1.1 where the class above had a constructor with three parameters. Now it has four. The extra parameter is ExecutionContextDao.

Here is my completely untested solution:

<bean id="jobRepository" class="org.springframework.batch.core.repository.support.SimpleJobRepository">
    <constructor-arg>
        <bean class="org.springframework.batch.core.repository.dao.MapJobInstanceDao"/>
    </constructor-arg>
    <constructor-arg>
        <bean class="org.springframework.batch.core.repository.dao.MapJobExecutionDao" />
    </constructor-arg>
    <constructor-arg>
        <bean class="org.springframework.batch.core.repository.dao.MapStepExecutionDao"/>
    </constructor-arg>
    <constructor-arg>  <!-- Extra constructor argument -->
        <bean class="org.springframework.batch.core.repository.dao.MapExecutionContextDao"/>
    </constructor-arg>
</bean>

Never used Spring Batch, but perhaps you can use more recent tutorial (I don't recommend downgrading to 1.x)?
