How do I handle multiple CXF endpoints in Camel?

Question

I have two endpoints:

 <cxf:cxfEndpoint address="http://localhost:9090/fileTransferService" id="FileTransferServiceEndpoint" serviceClass="FileTransferService">
     <cxf:properties>
           <entry key="dataFormat" value="POJO"/>
           <entry key="loggingFeatureEnabled" value="true"/>
     </cxf:properties>
 </cxf:cxfEndpoint>
 <cxf:cxfEndpoint address="http://localhost:9090/cardPaymentService" id="PaymentServiceServiceEndpoint" serviceClass="CardPayment">
     <cxf:properties>
           <entry key="dataFormat" value="POJO"/>
           <entry key="loggingFeatureEnabled" value="true"/>
     </cxf:properties>
 </cxf:cxfEndpoint>

Route for file transfer service

<from id="from1" uri="cxf:bean:FileTransferServiceEndpoint"/>
...

Route for cardPaymentService

<from id="from2" uri="cxf:bean:PaymentServiceServiceEndpoint"/>
...

Each endpoint is used in each route from some client. When my spying application loaded the routes, I cannot find the web services of cardPaymentService. But I can find the web services for fileTransferServices.

I want to provide multiple web services. How do I configure my route?

Thank you.

To help you better, could you please provide more details, including what version of Apache Camel are you using, more details of the route and the full stack trace of the error? — ShellDragon, Nov 11 '19 at 10:53

I use camel version 2.23.2.

After loading routes, I found only one web services. And when I reload the application, I found below exception.

I think you have to use two distinct ports (eg 9090 and 9091)- one per service.
