Invalid JobExecution, ID 0 not found.

I’m new to Spring and I’m trying to get my jobRepository working so it actually writes to my Oracle database tables.
I get the same error regardless of using Oracle or SqlServer for the repository database.
I know the connection is working based on previous errors but I keep getting this error about Invalid JobExecution, ID 0 not found.
I’m running the job just once.
I’m sure I’m missing something basic but have had no luck finding a complete example or solution on the net.
Any help would be appreciated.

Here is the exception:

org.springframework.batch.core.repository.dao.NoSu chObjectException: Invalid JobExecution, ID 0 not found.

My applicationContact.xml looks like this:
<bean id="oraDataSource"
class="org.springframework.jdbc.datasource.DriverM anagerDataSource"
destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:@localhost:1521:xe" />
<property name="username" value="system" />
<property name="password" value="password" />
</bean>

<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSou rceTransactionManager">
<property name="dataSource" ref="oraDataSource" />
</bean>


<bean id="jobRepository2"
class="org.springframework.batch.core.repository.s upport.JobRepositoryFactoryBean">
<property name="databaseType" value="oracle" />
<property name="dataSource" ref="oraDataSource" />
<property name="transactionManager" ref="transactionManager" />
</bean>

My job.xml looks like this:
<bean id="world" class="BatchProgram1">
<property name="message" value="World!" />
</bean>

<bean id="taskletStep" abstract="true"
class="org.springframework.batch.core.step.tasklet .TaskletStep">
<property name="jobRepository" ref="jobRepository2" />
</bean>

<bean id="myJob" class="org.springframework.batch.core.job.SimpleJo b">
<property name="name" value="simpleJob" />
<property name="steps">
<list>
<bean parent="taskletStep">
<property name="tasklet" ref="world" />
</bean>

</list>
</property>
<property name="jobRepository" ref="jobRepository2" />
</bean>

Why is it called 'jobRepository2' ? Do you have more than one?

You know, for such a simple answer... It worked. I was loading multiple repositories and that was the problem. I removed the other memory-based repository and everything worked !!!
Thanks :)
