[gaoyonglu]

<threadPoolProfile id="myDefaultProfile"

                           defaultProfile="true"

                           poolSize="1" keepAliveTime="1" maxPoolSize="1" maxQueueSize="1" rejectedPolicy="CallerRuns"/>

      <route id="sticallcumgmroute">

        <from uri="cxf:bean:cumgmStiwebEndpoint?dataFormat=MESSAGE"/>

        <log message="get sti call........................."/>

         <threads executorServiceRef="myDefaultProfile">

        <to ref="callRealService"/>

        <log message="get callcumgmRealService back............................."/>

        </threads>

    </route>

I want form endpoint use one threadpool and to endpoint use one threadpool.
