✔ Hellowebservice mit Jersey?

[flashray]

Hallo,

versuche mich seit gestern mit Jersey:
https://jersey.dev.java.net/

Hab das Helloworld Beispiel immer noch nicht zum Laufen bekommen!

Hab viel hin und her probiert, http4e meldet jedes mal das die angefragte Ressource nicht gefunden wird.

https://jersey.dev.java.net/use/getting-started.html
http://www.qalem.de/_jersey/

package com.sun.jersey.samples.helloworld.resources;

import javax.ws.rs.GET;
import javax.ws.rs.ProduceMime;
import javax.ws.rs.Path;

// The Java class will be hosted at the URI path "/helloworld"
@Path("/helloworld")
public class HelloWorldResource {

    // The Java method will process HTTP GET requests
    @GET 
    // The Java method will produce content identified by the MIME Media
    // type "text/plain"
    @ProduceMime("text/plain")
    public String getClichedMessage() {
        // Return some cliched textual content
        return "Hello World";
    }
}

Hat nun doch geklappt. Mit folgender URL:
http://localhost:8080/WebTest/helloworld
anstatt:
http://localhost:8080/helloworld

So einfach, aber auch doch so schwierig.

Hallo,

funktioniert wunderbar:

package de.tutorials;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.ProduceMime;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.UriInfo;

// The Java class will be hosted at the URI path "/helloworld"
@Path("helloworld")
public class HelloWorldResource {

    @Context
    private UriInfo context;

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

   /**
   * Retrieves representation of an instance of hello.world.HelloWorldResource
   * @return an instance of java.lang.String
   */
   @GET
   @ProduceMime("text/plain")
   public String getClichedMessage() {
       //Return some cliched textual content
       return ("Hello World! Here is " + context.getAbsolutePath());
   }
}

/**
 * 
 */
package de.tutorials;

import com.sun.jersey.api.container.httpserver.HttpServerFactory;
import com.sun.net.httpserver.HttpServer;

/**
 * @author Thomas.Darimont
 * 
 */
public class JerseyExample {

    /**
     * @param args
     */
    public static void main(String[] args) throws Exception {
        HttpServer server = HttpServerFactory.create("http://localhost:9998/");
        server.start();

        System.out.println("Server running");
        System.out.println("Visit: http://localhost:9998/helloworld");
        System.out.println("Hit return to stop...");
        System.in.read();
        System.out.println("Stopping server");
        server.stop(0);
        System.out.println("Server stopped");
    }

}

Ausgabe: Server console:
