SimpleJobLauncher and Queuing

I'm using the SimpleJobLauncher Thread Pool task executor to queue jobs. Let's say, I have three jobs

Code:

---

<job id="job1">
    <step ="jobStep1">
        <chunk>
        </chunk>
    </step>
</job>

<job id ="job2">
    <step="jobStep2">
      <chunk>
      </chunk>
      </step>
</job>

<job id="job3">
      <step id="jobStep3">
        <chunk>
      </chunk>
      </step>
</job>

I'm using the SimpleJobLauncher class and setting its task executor so that I can queue jobs. Synchronization is required in this
case. Below is my bean definition for the job launcher.

Code:

---

<beans:bean id="asynchJobLauncher"
                class="org.springframework.batch.core.launch.support.SimpleJobLauncher"
                p:jobRepository-ref="jobRepository">
                <beans:property name="taskExecutor">
                        <beans:bean
                                class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
                                <beans:property name="corePoolSize" value="1" />
                                <beans:property name="maxPoolSize" value="1" />
                                <beans:property name="queueCapacity" value="500" />
                                <beans:property name="keepAliveSeconds" value="600" />
                        </beans:bean>
                </beans:property>
        </beans:bean>

I want to chain jobs. Have one job call the next. I don't want to copy step definitions from one job into another. There is a possibility that the chain job will change one day and we'd like to make the change in one place rather than two.

This is what I do NOT want to do to chain jobs.

Code:

---

<job id="job1">
  <step ="jobStep1">
    <chunk>....
    </chunk>
  </step>
    <step="jobStep2">
      <chunk>....
      </chunk>
    </step>
</job>

---

I want do use the ref to another job like this:

Code:

---

<job id="job1">
    <step ="jobStep1">
      <chunk>....
      </chunk>
    </step>
    <step="jobStep2">
        <job ref="job2"/>
    </step>
</job>

However, this messes up the queueing. When I start job 1, it gets put into a STARTED state. I think start Job3 which gets queued. Once Job 1 completes, the queued job starts next, then Job2 runs. I need Job1 and Job2 to complete before running Job3. Can someone assist with how to go about this and still have a minimal amount of code?
