Question

La primera vez que pruebo un WebService usando jersey. El siguiente código que obtuve de un blog. Obtengo un error de 500 cuando estoy intentando el servicio web de Java usando el cliente jersey

javax.servlet.ServletException: Servlet.init() for servlet Jersey Root REST Service threw exception

Aquí traté de agregar el paquete que tampoco ayudó:

Se agregó solo un archivo jar jersey-bundle-1.14.jar. El siguiente es mi servidor de Jersey

package com.rest.server;

import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import com.rest.data.Hello;

// POJO, no interface no extends

// The class registers its methods for the HTTP GET request using the @GET annotation. 
// Using the @Produces annotation, it defines that it can deliver several MIME types,
// text, XML and HTML. 

// The browser requests per default the HTML MIME type.

//Sets the path to base URL + /hello
@Path("/hello")
public class HelloWorldRest {

 @GET
 @Path("/{param}/")
 public String getMsg(@PathParam("param") String msg) {

  String output = "Jersey say : " + msg;

  return output;

 }
 @GET
 @Path("/world")
 public String getFixedMsg(String msg) {

  String output = "Jersey say : fixed path" + msg;

  return output;

 }
 // This method is called if TEXT_PLAIN is request
 @GET
 //@Path("helloworld")
 @Produces(MediaType.TEXT_PLAIN)
 public String sayPlainTextHello() {
  System.out.println("sayPlain");
  return "Hello Jersey";
 }

 // This method is called if XML is request
 @GET
 //@Path("helloworld")
 @Produces(MediaType.TEXT_XML)
 public String sayXMLHello() {
  System.out.println("sayXML");
  return "" + " Hello Jersey" + "";
 }

 // This method is called if HTML is request
 @GET
 //@Path("helloworld")
 @Produces(MediaType.TEXT_HTML)
 public String sayHtmlHello() {
  System.out.println("sayHTML");
  return "<html> " + "<title>" + "Hello Jersey" + "</title>"
    + "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
 }

 // This method is called if JSON is request
 @GET
 //@Path("helloworld")
 @Produces(MediaType.APPLICATION_JSON)
 public Hello sayJsonHello() {
  return new Hello("Hello", "Jersey");
 }

 @POST
 @Produces(MediaType.APPLICATION_JSON)
 public Hello createHello(Hello hello)
 {
  System.out.println("post");
  return hello;
 }

}''

Actualmente estoy intentando solo con GET presionando la siguiente url http://localhost:8080/RestFulWeb/hello , http://localhost:8080/RestFulWeb/hello el error 505.

¿Me perdí archivos jar, pero no obtuve ningún error de tiempo de compilación.

Answer 1

Esto es causado por la falta de asm.jar,

Agrega esta dependencia

<dependency>

    <groupId>asm</groupId>

    <artifactId>asm</artifactId>

    <version>3.3.1</version>

</dependency>

Answer 2

Mientras escribía un servicio web recibí el siguiente error:

Incluí asm.jar en mi proyecto de Java y el error desapareció. Estaba siguiendo los pasos de restful-web-services-first-application-mock-service-using-pure-java
