  <p>When my Spring controller handles the connection:</p>
  
  <pre><code>@RequestMapping(value = "/user", method = RequestMethod.GET)
      public @ResponseBody User getUser(@RequestParam(value="id", required=true) int id) {
          User user = null;
  
          ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("spring-config.xml");
          UserService userService = (UserService) context.getBean("userService");
  
          user = userService.getUser(id);
          context.close();
  
          return user;
      }
  </code></pre>
  
  <p>It does a getUser on the userService:</p>
  
  <pre><code>import java.util.List;
  
  import org.springframework.beans.factory.annotation.Autowired;
  import org.springframework.stereotype.Component;
  
  @Component
  public class UserService {
  
      private UserDAO userDao;
  
      public UserDAO getUserDao() {
          return userDao;
      }
  
      @Autowired
      public void setUserDao(UserDAO userDao) {
          this.userDao = userDao;
      }
  
      public void addUser(User user) {
          getUserDao().insert(user);
      }
  
      public User getUser(int id) {
          return getUserDao().load(id);
      }
  
      public List&lt;User&gt; fetchAllPersons() {
          return getUserDao().selectAll();
      }
  }
  </code></pre>
  
  <p>Which uses the userDao to find the entity:</p>
  
  <pre><code>import java.util.List;

  import javax.persistence.PersistenceContext;
  import javax.persistence.Query;

  import org.springframework.transaction.annotation.Transactional;
  
  @Repository("userDao")
  @Transactional(propagation = Propagation.REQUIRED)
  public class UserDAO {
  
      private static final String SELECT_QUERY = "select u from users";
  
      @Qualifier(value = "entityManagerFactory")
      private EntityManager entityManager;
  
      public EntityManager getEntityManager() {

      public void setEntityManager(EntityManager entityManager) {
          this.entityManager = entityManager;
      }
  
      public void insert(User user) {
          entityManager.persist(user);
      }
  
      public User load(int id) {
          return entityManager.find(User.class, id);
      }
  
      public List&lt;User&gt; selectAll() {

  <p>What do I need to do to resolve this error?  </p>
  
  <p>Honestly though, when this is resolved, I'm probably just going to get a JndiException.  What do you think might also be causing that?  </p>
