Calling springWs for validation of message from Camel - web-services

Question

In my application, I have to validate the authorization of incoming message via calling a webservice.e.g if the user belongs to the authorised group then only process the message. For this, I have to build the authorizationRequest from one of the properties of the incoming message say userId(not the whole incoming message) and send to webservice.
I am new to camel. To achive this in a non-camel application I would have created a webservice client, make a call with userId(param) and process the response.
Main Camel route :
from( <URI> ).routeId("UpdateRoute")
.process("AuthorizationProcessor")
.process( "ValidateProcessor" )
.choice()
.when(matches(cond1)).to("cond1Processor")
.when(matches(cond2)).to("cond2UpdateProcessor")
.otherwise().to( "invalidconditionProcessor" );
}
With Camel, I am calling a custom processor AuthorizationProcessor and making a webservice call as I can do in non camel application.
I am not utilising Camel properly.What should be the appropriate way to make the webservice call .
I tried creating a route AuthorizationRoute and into I can use spring ws component to make the call.But not sure how this route will be invoked and where should I build the request.

Camel has a couple of components able to make Web Service calls (REST or SOAP). One of the most popular ones is camel-cxf, which (you guessed it, uses Apache CXF to make WS calls.
There is a myriad of options available, but it boils down to including:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-cxf</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>
And then in your route:
from( <URI> ).routeId("UpdateRoute")
.to("cxf:http://address/service?serviceClass=com.MyClass")
.process( "ValidateProcessor" ) // process the resoponse here
.choice()
.when(matches(cond1)).to("cond1Processor")
.when(matches(cond2)).to("cond2UpdateProcessor")
.otherwise().to( "invalidconditionProcessor" );
