HTTP Status 404 - spring mvc java web

I am studying the Spring Framework. I got an error while following a video tutorial. I can't figure out what's wrong. I am using Maven 3.5.0 and runs it in Tomcat 7. I am using GET as the request method.

I am using eclipse as my IDE. It says in the description:
The requested resource is not available.

I have solved it but I do not unrderstand. Does it have to require the base-package="com.in28minutes" in dispatcher servlet to match the packages names?

HTTP 404 error while buiding REST API on Java

I am starting with restapi and thought of doing it with a basic program found on internet.
Sharing you the code.
The class File:
package com.java2novice.restful;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;
#Path("/publish")
public class RestEasyExample {
#GET
#Path("/{message}")
public Response publishMessage(#PathParam("message") String msgStr){
String responseStr = "Received message: "+msgStr;
return Response.status(200).entity(responseStr).build();
}
}

I am using the jersey 2.0.
I have deployed the war and placed it in webapps folder of Tomcat.
I have tried calling it using two urls-
http://localhost:8080/RestfulWebServices/publish/abc
and
http://localhost:8080/RestfulWebServices/publish?message=abc
But i still keep on getting HTTP 404 not found.
Please assist me in where i am missing something.
Thanks

I think you are mixing resteasy with jersey.
In either way, the <listener> is required param in web.xml
Try adding following in your web.xml file:
<listener>
<listener-class>
org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap
</listener-class>
</listener>
You should also consider using restEasy's servlet container rather using Jersey.
<servlet>
<servlet-name>resteasy-servlet</servlet-name>
<servlet-class>
org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher
</servlet-class>
</servlet>

Try using rest application container with this configuration over web.xml configuration.
package com.java2novice.config;
import org.glassfish.jersey.server.ResourceConfig;
import java.util.Collection;
#javax.ws.rs.ApplicationPath("v1")
public class ApplicationConfig extends ResourceConfig {
public ApplicationConfig() {
// package where all your api lives
packages("com.java2novice.restful");
}
#Override
public Collection<Strinzg> getPropertyNames() {
return super.getPropertyNames();
}
}
Then visit /v1/your-endpoint

I referred other stack overflow solutions to resolve them. But nothing helped me. Can anyone help me to resolve the issues.

REST api 404 on mapping

I am trying to create a rest api using jersey on glassfish 4 server.
Currently i am getting error 404 whenever I go to my mapping:
http://localhost:8080/LibraryRestTest/api/books
Sadly i get 0 errors on my glassfish console log. I have also tried manually deploying my war on glassfish admin console to result in the same error.
Is there something I haven't yet implemented ?
All files i have created in my project :

}
#GET

public Book getById(#PathParam ("id") int id){
return null;
}
}

Instead of mapping a jersey servlet in web.xml, you could configure your REST endpoint using Java code using standard Java EE 7 API (Application and #ApplicaionPath:
#ApplicationPath("api")
public class ApplicationConfig extends Application {
}
This will automatically attach all resources annotated with #Path to the api suffix.
If you do not want all resources to map to this suffix, you may list each class in particular, if you override getClasses() method:
#ApplicationPath("api")
public class ApplicationConfig extends Application {
#Override
public Set<Class<?>> getClasses() {
return Arrays.asList(com.koen.library.BookResource.class);
}
}

The fix to my problem was:
<param-value>true</param-value>
I had to add that line in my web.xml.
Now i don't get any 404 error on my mapping.
