JBoss Fuse CXF-RS REST Issue - 'No services have been found'

问题

I'm creating a REST Service with Apache Camel and CXF-RS, using the following tutorial: https://www.javainuse.com/camel/apache_camel_rest_cxfrs

I've set up the code as shown in the tutorial and followed the steps correctly. After building the Maven project, I have successfully been able to install the bundle on Apache Karaf, using the SNAPSHOT file created. (A new Bundle ID was created).

When I run the command to 'start' the newly created bundle, it seemingly works with no errors being shown. However, when I access http://localhost:8181/cxf as mentioned towards the end of the tutorial, it says 'No services have been found':

Can you please advise me on what could be causing this problem?

Thank you.
