Rest Webservice with netbeans 8.2 - netbeans

Question

I have created a very basic Java Web Application with Netbeans 8.2
Here is the steps i have done:
"File" > "New Project" : "Java Web" > "Web Application"
I have created a Java Class by right clicking on project name. Then New > Java Classe
Here what i have put in this java class:
package pkg1;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
public class TestService
{
#Path("/test")
#GET
#Produces("text/plain")
public String methode_test()
{
return "Hello test";
}
}
I have no compilation problem.
GlassFish is launched, but i got a 404 error if i try to go to /test url...
Any idea ?
Thanks

I made a couple of small changes to get your code working using NetBeans 8.2, JDK 8 and Glassfish 4.1.1 on Windows 10:
Add a #Path annotation on the class as well as methode_test().
Add a second class to pkg1 named ApplicationConfig which extends javax.ws.rs.core.Application as shown below.
This is the revised TestService class:
package pkg1;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
#Path("/demo")
public class TestService
{
#Path("/test")
#GET
#Produces("text/plain")
public String methode_test()
{
return "Hello test";
}
}
This is the additional class you need to add:
package pkg1;
import javax.ws.rs.core.Application;
#javax.ws.rs.ApplicationPath("sample")
public class ApplicationConfig extends Application {
}
My project was named DemoService, and therefore had a context root of DemoService, but in your case the URL to use would probably be: http://localhost:8080/TestService/sample/demo/test
Notes:
See this answer to the SO question What is that Application class lifecycle of a rest service? for more details on why you need to create a class which extends that Application class.
For convenience you can set the default path to be used in the browser when testing your project:
Open the Properties window of your project from the Projects panel.
Select Run and set the values of Context Path and Relative URL as appropriate:
NetBeans 8.2 provides a basic "Hello World" REST application that you can create in just a few seconds using the Project Wizard: File > New Project... > Samples > Web Services > REST: Hello World.
