如何解决此NetBeans错误：“确保项目已成功部署且服务器正在运行”？

Question

我使用NetBeans 8.2和jboss-eap 7.1编写了一个Maven项目，用于使用RESTful Web服务的Web应用程序，但是当我测试我的代码时，NetBeans向我显示了这个警告：

Make sure the project has been deployed successfully and the server is running.

这是我的代码：

HelloWorld.java

package com.myws.webservice;

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

@Path("/")
public class HelloWorld {


    @Inject
    HelloService helloService;

    @GET
    @Path("/xml")
    @Produces({ "application/xml" })
    public String getHelloWorldXML() {
        return "<xml><result>" + helloService.createHelloMessage("World") + "</result></xml>";
    }

}

HelloService.java

package com.myws.webservice;

public class HelloService {

    String createHelloMessage(String name) {
        return "Hello " + name + "!";
    }    
}

pom.xml中的依赖项

了解如何从此处继续处理此错误的任何帮助？谢谢！
