implementation relays on <a shape="rect" class="external-link"

delegate the processing of the batch item to the Camel infrastructure. The item
to process is sent to the Camel endpoint as the body of the message.</p>

job execution events to the Camel endpoint.</p>

+<p>The <tt>org.springframework.batch.core.JobExecution</tt> instance produced
