I'm trying to create jersey resources programatically (without
Annotations). I have a method raiseAlarm that takes a Name and id as input
parameter. I want to take Name from the JSON input and I want id to come
from path parameter. The code looks some thing like this...
{code}

public class JerseyExample {
    public static void main(String[] args) {
      JerseyExample deployer = new JerseyExample();
      deployer.init();
    }


public static class BaseResource extends ResourceConfig {
    public BaseResource() {
        init();
    }

    public void init() {
        try {
            Resource.Builder resourceBuilder2 = Resource.builder();
            resourceBuilder2.path("/raiseAlarm/{id}");
            ResourceMethod.Builder method2 = resourceBuilder2.addMethod("POST")
                    .consumes(MediaType.APPLICATION_JSON_TYPE)
                    .produces(MediaType.APPLICATION_JSON_TYPE)
                    .handledBy(this,
this.getClass().getMethod("raiseAlarm", Name.class, String.class));

            Resource childResource1 = resourceBuilder2.build();

            Resource.Builder resourceBuilder = Resource.builder();
            resourceBuilder.path("/employee/status");
            resourceBuilder.addChildResource(childResource1);
            Resource rootResource = resourceBuilder.build();
            registerResources(rootResource);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public String raiseAlarm(Name notification,_at_PathParam("id") String id) {
        System.out.println("INSIDE RAISE ALARM ");
        System.out.println(notification.toString() + " ID: "+id);
        return "Result";
    }

    public void destroy() {

    }

     public static class Name {

        String firstName;
        String lastName;
        String middleName;

        public String getFirstName() {
            return firstName;
        }

        public void setFirstName(String firstName) {
            this.firstName = firstName;
        }

        public String getLastName() {
            return lastName;
        }

        public void setLastName(String lastName) {
            this.lastName = lastName;
        }

        public String getMiddleName() {
            return middleName;
        }

        public void setMiddleName(String middleName) {
            this.middleName = middleName;
        }

        @Override
        public String toString() {
            return firstName + " " + middleName + " " + lastName;
        }
    }
}

public void init() {

    Server server = new Server();

    ServletContextHandler context0 = new
ServletContextHandler(ServletContextHandler.SESSIONS);
    ServletHolder serveltHolder1 = new ServletHolder(new
ServletContainer(new BaseResource()));

    context0.addServlet(serveltHolder1, "/*");
    context0.setVirtualHosts(new String[]{"@external"});
    ServerConnector connector = new ServerConnector(server);
    connector.setHost("localhost");
    connector.setPort(9069);
    connector.setName("external");

    HandlerCollection collection = new HandlerCollection();
    collection.addHandler(context0);
    server.setHandler(collection);
    server.addConnector(connector);


    try {
        server.start();
        server.join();
    } catch (Exception e) {
        e.printStackTrace();
    }
    }
}


{code}

The above code works. I want to know a way in which I can declare the Path
paramenters or Query parameters programatically, so that I can define my
method signature as raiseAlarm(Name notification,String id) and avoid
@PathParam("id") annotation.
