How to do an asynshronous web service call to a camel route ?

[kmohite]

I have a camel route that's invoked by a web service call. Here I wanted to
know how I can do the web service call asynchronously.
Following is the route:

1. <camelContext id="device_context"
xmlns="http://camel.apache.org/schema/spring";>
2. <route>
3. <from uri="cxf:bean:soapMessageEndpoint?dataFormat=MESSAGE" />
4. <process ref="typecastProcessor" id="convertToString" />
5. <split strategyRef="aggregatorStrategy">
6. <xpath>//deviceList</xpath>
7. <unmarshal>
8. <jaxb prettyPrint="true"
contextPath="com.cisco.dlcc.cxf.webservice.model" />
9. </unmarshal>
10. <process ref="dlcAppProcessor" id="dlcapp" />
11. </split>
12. <process ref="transformProcessor" id="Transform" />
13. 
14. <process ref="dlciCallPrepareProcessor" id="dlciPrepare" />
15. <to uri="cxf:bean:serviceEndpoint" id="DLCIWebSvcCall"/>
16. <process ref="parserProcessor" />
17. </route>
18. </camelContext>

Explanation:

a. At line 3, the input soap xml is received from the web service call made
by the web service client. The input xml is a list of devices as here:
<deviceList><var1>?</var1&lt;/deviceList>
<deviceList><var1>?</var1&lt;/deviceList>
<deviceList><var1>?</var1&lt;/deviceList>

b. At line 4, the input xml is converted to string.

c. At line 5, the the input xml is split on device list and this is fed to
the processor dlcAppProcessor (line 10). This processer does some processing
for each device.

d. At line 12, the processor transformProcessor aggregates the output of all
the devices and saves it for the next endpoint.

e. At line 14,15,16 the aggregated information is sent to other system using
a web service call.

Here the operations from line 4 onwards (after the input is received) are
time consuming and hence I do not want the web service client to wait for
the web service call to return after completing the entire flow. I want the
the web service call to return immediately after I receive the input xml and
let remaining processing continue asynchronously.
I wanted to know how I can achieve this using asynchronous web service call
?
