<route id="callstiroute">

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

        <log message="get XXXXXXXXXXXXXXXXXXXX call"/>

        <to ref="callRealService"/>

        <log message="get real webservice back"/>

    </route>

I want to know ,this  <from> <to> if sync.

how to I make camel cxf   <from>   <to> is async.

you know,if  target service need a lot of time to get reply,this sync will make route use many thread!.
