How do paths work in a Java deployed REST web service?

Under Tomcat and Jersey libraries I created a REST web service described in this class:

package Servicios;

import javax.ws.rs.core.Context;
import javax.ws.rs.core.UriInfo;
import javax.ws.rs.PathParam;
import javax.ws.rs.Consumes;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.GET;
import javax.ws.rs.Produces;

@Path("service")
public class ServiceResource {

    @Context
    private UriInfo context;

    /**
     * Creates a new instance of ServiceResource
     */
    public ServiceResource() {
    }

    @GET
    @Produces("text/html")
    public String getHtml() {

        return "<h1>Here we are, at the contemplation of the most simple web service</h1>";
    }

    @PUT
    @Consumes("text/html")
    public void putHtml(String content) {
    }
}

So, as I set it before accessing to http://localhost:8080/GetSomeRest makes the default created .jsp file created.

I set in project propierties (using NetBeans) a relative URL as webresources/service, so service part is same defined in @Path("service"). All works ok, going to http://localhost:8080/GetSomeRest/webresources/service makes the web service be consumed.

But what if I want to consume that service right from http://localhost:8080/GetSomeRest/service? I tried to set only service in such relative URL and I got an Error 404 message going to http://localhost:8080/GetSomeRest/service

How do virtual paths work?

What would it mean to add an alias to a web service?

Just for information

The path segment webresources is set in the code by netbeans in the package

org.netbeans.rest.application.config - ApplicationConfig Class into your own project!!! so change it and it's done...

The path segment webresources is not set in the code you provide so I will guess what your code looks like.

A JAX-RS application can be configured with a class extending javax.ws.rs.core.Application. Such a class can be annotated with @javax.ws.rs.ApplicationPath(). My guess is that in your project this annotation is set to

@javax.ws.rs.ApplicationPath("webresources")

So the URL of a JAX-RS resource class is build from these parts.

  1. http://localhost:8080/ - host and port
  2. GetSomeRest - the context, normally the name of the deployed .war file
  3. webresources - the value of the @ApplicationPath annotation
  4. service - the value of the @Path annotation of the class

I recommend not to skip step 3.

The value of the @ApplicationPath annotation can be overridden by a servlet-mapping element in the web.xml.
