    NullPointerException while following "Getting Started" tutorial

    Dennis Crissman Newbie

      I am evaluating arquillian and following http://arquillian.org/guides/getting_started/ to learn about it. I am getting a NPE when GreeterTest attempts to use the @Inject(ed) Greeter parameter. Not sure what I am doing wrong, but seem like DI isn't working.

       

      Note: I had to add javax.ejb-api, validation-api & javax.el-api maven dependencies myself as they were not in the tutorial.

       

      Any help getting this to work would be appreciated.

       

      package org.arquillian.example;
      
      import java.io.PrintStream;
      
      /**
      * A component for creating personal greetings.
      */
      public class Greeter {
          public void greet(PrintStream to, String name) {
              to.println(createGreeting(name));
          }
      
          public String createGreeting(String name) {
              return "Hello, " + name + "!";
          }
      }
      

       

      package org.arquillian.example;
      
      import org.jboss.arquillian.container.test.api.Deployment;
      import org.jboss.arquillian.core.api.annotation.Inject;
      import org.jboss.arquillian.junit.Arquillian;
      import org.jboss.shrinkwrap.api.ShrinkWrap;
      import org.jboss.shrinkwrap.api.asset.EmptyAsset;
      import org.jboss.shrinkwrap.api.spec.JavaArchive;
      import org.junit.Assert;
      import org.junit.Test;
      import org.junit.runner.RunWith;
      
      @RunWith(Arquillian.class)
      public class GreeterTest {
      
          @Deployment
          public static JavaArchive createDeployment() {
              return ShrinkWrap.create(JavaArchive.class)
                      .addClass(Greeter.class)
                      .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
          }
      
          @Inject
          Greeter greeter;
      
          @Test
          public void should_create_greeting() {
              Assert.assertEquals("Hello, Earthling!",
                      greeter.createGreeting("Earthling"));
              greeter.greet(System.out, "Earthling");
          }
      }
