Java EE 批处理作业可以等待事件吗？

Question

I should implement business flow with many async calls to external system: I send async SOAP and don't wait it (I only get ack), response (SOAP message on my endpoint) can be send back in hours and than I continue my flow. Could java ee batch (JSR 352) do this? Or I should to look up something else?

UPDATE: One is possible simple solution is that one step would read data from blocking queue, but I don't like this solution. I could lock my flow if count of waiting step would be more than available threads

UDPATE2:

<job id="myJob" xmlns="http://xmlns.jcp.org/xml/ns/javaee" version="1.0">
    <step id="myStep" next="myStep2" >
        <batchlet ref=".MyBatchlet"/>
        <stop on="COMPLETED" />
    </step>
    <step id="myStep2" >
        <batchlet ref="MyBatchlet2"/>
    </step>
</job>

I could continue by this code:

long jid = jo.start("myJob", new Properties());
long jid2 = jo.restart(jid, new Properties());

MyBatchlet2 never starts

据我所知，没有开箱即用的方式来实现您想要的，但也许您可以使用 stop() 和 restart() 方法来实现解决方法。
