using camel to call multiple web services asynchronously
I call a webservice for my application for a user action, I have spring,cxf
client , I use this client to call the webservice, now our requirement added
new webservice call , so I have to call two webservices , the old one and
the new one, my initial plan is in a method I will call each webservice,
club the result return the result, this will take more time as I have to
wait for first webservice to return result then call second webservice
, other way is to call each webservice in a thread asynchronously this way
both webservices are called at the same time , an overall time is
reduced,does camel has anything inbuilt for calling multiple webservices
asynchronously ?

Or for using cxf, you can also use JAX-WS asynchronous invocation
model directly, which allows the client thread to continue after
making a two-way invocation without being blocked while awaiting a
response from the server, you can check jaxws_async example shipped
with cxf kit to get more details.

The ProducerTemplate have API for invoking async with either a Future
as return value, or a callback.
Then you can use that API from a Java bean and invoke the 2 web
services async, and assemble the replies using the Java API.
Some details here

Hi fachhoch,
the example Willem mentioned is good matching case you could consider to
walk through. However in that example there's no asynchronous invocation of
the banks (which's apparently what you want to have) as multicast() invokes
the endpoints one after the other, so that in your case you should add
parallelProcessing() into your DSL, something like:
from("...").multicast().parallelProcessing().to("...", "...");

It you take a look at the loan-broker example[1], you can see we could
send the request to multiple web services at the same time, that could
also some some time :)
