Can't find the request for http://localhost:8082/{params}'s Observer

Question

I have a very simple Java REST service code concept here.

The problem is that when I am hitting the URL the below message is showing up in the console: Can't find the request for http://localhost:8082/REST/services/patientservices/getallpatients's Observer

I am using cxf.jaxrs.component-scan=true for spring to read the annotations.

Below are the classes and configuration file:

There was a mistake in the pom.xml file.

Instead of jaxws dependency it should be jaxrs dependency.

<dependency>
