I am starting the development of Webservice Restful Jersey in Java and I am not able to connect to realize a simple Hello World.

I added the jar:

asm-3.1jar
jersey-core-1.19jar
jersey-server-1.19jar
jersey-Servlet-1.19jar
jrr311-api.1.1.jar

I created the Hello class:

package com.k19.restful.resources; 

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

@Path("/helloworld") 
public class Hello {

    @GET @Produces("text/plain") 
    public String showHelloWorld() { 
        return "Olá mundo!"; 
    }

}

I set up web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app> 
    <display-name>jersey-tutorial</display-name>
    <servlet> 
        <servlet-name>Jersey REST Service</servlet-name> 
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param> 
            <param-name>com.sun.jersey.config.property.packages</param-name> 
            <param-value>com.k19.restful.resources</param-value>
        </init-param> 
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping> 
        <servlet-name>Jersey REST Service</servlet-name> 
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

I’m using Tomcat, it boots normally... but when I enter the url:

http://localhost:8080/jersey-tutorial/helloworld

Error 404. Door is 8080...

Is there any other procedure I need to do?

try to put in your method also for example @Path("/showHelloWorld") and then access: http://localhost:8080/jersey-tutorial/helloworld/showHelloWorld

Paula, I tested your example here and it’s OK. Can you include the Tomcat startup log? Maybe by logging we can see what it might be. Probably "root classes" were not found, so 404, that is, did not publish the resource.

Bruno, yes I can! I opened in the eclipse a webservice that I had already made with SOAP and ran right. I think some configuration is missing, for example Axis.I will edit the question and put the log

Paula, thank you for updating. But you would need the Tomcat log starting with the jersey-tutorial and not with other projects. The problem is not the lack of axis, it is a SOAP implementation. Try starting Tomcat with only jersey-tutorial published by the log I may be able to help you. Also, if possible, show the directory structure of jersey-tutorial, may be that the web.xml is not being published.
