Hi Glen,
My comments are in the mail.

Hello again, I have a few more questions. I'm using a CXF-based web
service provider running on Tomcat, using CXF's JAX-WS front end. Its
WSDL is located on my machine as follows:
http://localhost:8080/doubleit/services/doubleit?wsdl.
Questions about the CXF component page[1]:
1.) Using this type of URI: "cxf://address?options", which of the
options--wsdlURL, serviceClass, serviceName, portName--do I have to
provide? It seems strange to need to provide any of these options,
because the first can be obtained via "?wsdl" by default, the second is
not necessarily known by the client, and the third and fourth are
readable from the WSDL--perhaps these options are needed only by CXF's
simple frontend?
Yes , the endpoint's address can get from the WSDL , but if the WSDL has
more than two ServiceNames or PortNames, you need to specify the right
one that you want.
The URI "cxf://address?options" is common pattern for cxf endpoint ( not
only the CXF provider but also CXF consumer), and camel-cxf component
can't know which frontend will be used if it do not check the annotation
from the serviceClass, so the serviceClass and address in required
parameter for the camel-cxf component, the others parameters are optional.
2.) Using the same type of URI, how do I specify the wsdl:operation I
wish to be calling? I.e., if my wsdl has doubleIt, tripleIt, and
quadrupleIt wsdl:operations, how do I specify the one that I want?
You can't specify the operation name by using the URI such as the
methodName now, since I want to the camel-cxf endpoint provider can
invoke more than one operation.
You can change the operation name by setting the message header with the
cxfConstants.OPERATION_NAME.
You can find the example here [1]

Hi Glen,
From your requirement , you need to start a "DoubleIt" web service your
self, maybe the same time that Camel context start.
Here is the code snippet for setting up the router.
from("test-jms:queue:test.queue").to("cxf://http://SERVICEADDRES?SEI=yourSEI...";).to("file://test");
If you just feed the queue with a series of numbers, you need to change
the message for the "DoubleIt" web service in a processer first.
Here is an example[1] to show you how to make a web service call by
setting the message header with the Web service operation name , and
message body with the parameters. You can get the result from the
exchange.getOut().getBody(), which is a list.

Hello,
I'm trying to create a Camel example so I can learn more about the
product. What I'd like to do is feed a queue a series of numbers, which
would automatically be fed as the lone parameter to a "DoubleIt" web
service, the output of which (i.e., the input number doubled in value)
would then be fed to a file.
I understand how to write from a message queue to a file from this
example[1], and also, the camel-cxf example[2] gives me a pretty good
idea of how web service calls are made, but I'm not sure how to have a
web service automatically activated based on what is fed through a
queue; further, how to have the number that is fed into the queue serve
as the lone parameter to that web service call (which component, if any,
must occur between the queue and the web service so the number off the
queue is put into the SOAP request.) Any guidance or known samples
would be appreciated.
Thanks,
Glen
