Why my jaxrs APIs has the application name as application path?

I created a simple version API with rest-easy and wildfly, everything should works but the application path has the name of my project:

My version API return the version number from my pom.xml: The URI should be http://localhost:8080/version
but to acces it this is http://localhost:8080/projectName/version.
To acces to the open api file : The URI should be http://localhost:8080/openapi
but this is http://localhost:8080/projectName/openapi

I tried to extend Application to set the @ApplicationPath("/") but it's not working, it just allowed me to add element on the application path
example: http://localhost:8080/projectName/test/....
How can I set the application path to the root (/) and remove the projectName ?

JaxRSActivator class:

@ApplicationPath("/")
public class JaxRSActivator extends Application {

    public JaxRSActivator()
    {
        super();
    }
}

VersionFacade class:

@Path("/version")
@Tags
public interface VersionFacade {
    @GET
    @Produces(TEXT_PLAIN)
    @Operation(summary = "Application version", 
    responses = {
            @ApiResponse(responseCode = "200", 
                    description = "Version number",
                    content = @Content(mediaType = TEXT_PLAIN, schema = @Schema(implementation = String.class)))})
    String getVersion();
}

web.xml file:

<?xml version="1.0" encoding="UTF-8"?>

Solution

Jboss wildfly use the Web module name (projectName.war) as default context root. To set it you need to:

Add the WEB-INF/jboss-web.xml file in your Web module:
(if you don't package your app in an EAR file)

<jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="
      http://www.jboss.com/xml/ns/javaee
      http://www.jboss.org/j2ee/schema/jboss-web_5_1.xsd">
    <!-- Set context root to / -->
   <context-root>/</context-root>
</jboss-web>

Or add the META-INF/application.xml file in your EAR:
(if you package your app in an EAR file)

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/application_8.xsd" version="8">
  <display-name>projectName-ear</display-name>
  <module>
    <web>
      <!--My Web module -->
      <web-uri>projectName-ws.war</web-uri>
      <!-- Set context root to / -->
      <context-root>/</context-root>
    </web>
  </module>
  <module>
    <!-- other EJB module -->
    <ejb>projectName-core.jar</ejb>
  </module>
</application>

If you use Eclipse, careful it sometimes don't publish your application.xml so you need to put it manually in your Wildfly standalone/deployments folder.
