I am trying to inject Spring data repository (Elasticsearch in this instance) in SE application, using Weld SE.
Repository
public interface EmployeeRepository extends ElasticsearchRepository<Employee, String> {
List<Employee> findEmployeesByAge(int age);
List<Employee> findEmployeesByName(String name);
List<Employee> findEmployeesBySkillsIn(List skills);
}
Defining ElasticsearchTemplate:
#ApplicationScoped
public class ElasticsearchTemplateProducer {
#Produces
public ElasticsearchOperations createElasticsearchTemplate() {
Client client = null;
try {
client = TransportClient.builder().build()
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
} catch (UnknownHostException e) {
e.printStackTrace();
}
return new ElasticsearchTemplate(client);
}
}
Main (application is executed with org.jboss.weld.environment.se.StartMain) is as simple as:
public class Main {
#Inject
private Service repository;
public static void main(#Observes ContainerInitialized event){
}
}
Dependencies are:
<dependencies>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-elasticsearch</artifactId>
<version>2.0.2.RELEASE</version>
<exclusions>

I've excluded spring context, but I get same exception whether or not I exclude context.
In resources\META_INF\beans.xml:

What is the cause of this problem?
After a bit of debugging, I've noticed that no beans are being stored in elasticsearchOperationsMap in CDI extension ElasticsearchRepositoryExtension during processing beans phase, which causes an exception to be thrown later.
For now, I am using a workaround.
I add annotation #NoRepositoryBean to interface:
#NoRepositoryBean
public interface EmployeeRepository extends ElasticsearchRepository<Employee, String>
And then use the following #Produces method:
#Produces
public EmployeeRepository getEmployeeRepository() {
Client client = null;
try {
client = TransportClient.builder().build()
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
} catch (UnknownHostException e) {
e.printStackTrace();
}
ElasticsearchRepositoryFactory elasticsearchRepositoryFactory = new ElasticsearchRepositoryFactory(new ElasticsearchTemplate(client));
return elasticsearchRepositoryFactory.getRepository(EmployeeRepository.class);
}

I have created a SpringBoot CXF soap service from an existing WSDL file. I can now access WSDL from my service running on embedded tomcat from the springboot application. When I am trying to send a request to the service from soap-ui, the control reaches the implementation of the service method and then while it access the #Autowired service layer, it throws all NPE, as the service object is null (I have seen this while debugging). If I manually create (new Service() by commenting out the #Autowired object), the flow can reach the service implementation and then the DAO object fails as it cannot #Autowire the DAO Impl, further when i create the manually DAO Impl object it fails at #PersistenceContext, as it the entity manager is null.
I have made sure service is annotated with #Service, DAO layer with #Repository, still the issue persists. Also i have added #ComponentScan and giving all the package names, still i am getting null for all #Autowired.
Code below: Configuration class
#SpringBootApplication
public class EmWebSvcBootApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(EmWebSvcBootApplication.class, args);
}
public static final String SERVICE_NAME_URL_PATH = "/em";

#Bean(name=Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
return new SpringBus();
}
#Bean
public ServletRegistrationBean cxfServlet() {
ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new CXFServlet(), SERVICE_NAME_URL_PATH + "/*");
// Add custom Title to CXF´s ServiceList
Map<String, String> initParameters = servletRegistrationBean.getInitParameters();
initParameters.put("service-list-title", "My Test service");
return servletRegistrationBean;
}

I have added all the configurations that i am using, any help to fix this is highly appreciated. Basically all the #Autowired services, data layers, and entity managers are not loaded (as i see them as null in the debug).
I have been able to fix the issue based on the info from https://github.com/codecentric/cxf-spring-boot-starter

I am trying to inject and EJB 3.1 in one of my RESTful services. I've followed the post: Inject an EJB into JAX-RS (RESTful service) and tried all options except building an injection provider. The current solution that I am trying uses a combination of #RequestScoped and #Inject, but my injected bean variable is still null. I have a beans.xml in the /WEB-INF folder.
How can I inject an EJB into my REST service class?
UserService
#Local
#Path("user/v1")
#Produces(MediaType.APPLICATION_JSON)
public class UserServiceV1 implements SystemLogger {
#Inject
private ApplicationBean appBean;
#GET
#Path("pingbean")
#Produces(MediaType.APPLICATION_JSON)
public Response pingAppBean() {
if(appBean == null) {
return Response.status(Response.Status.UNAUTHORIZED).entity("{\"faild\": \"App bean is null\"}").build();
}
String message = appBean.getHello();
return Response.status(Response.Status.OK)
.entity(message)
.build();
}
}
ApplicationBean
The SystemHandler resides in jar module and is a standard class with business logic.
#Stateless
#Local
public class ApplicationBean implements ApplicationBeanLocal {
#Override
public String getHello() {
return "Hello from ApplicationBean";
};
}
JAX-RS configuration
#ApplicationPath("service")
public class ApplicationService extends Application {
#Override
public Set<Class<?>> getClasses() {
Set<Class<?>> resources = new HashSet<>();
resources.add(UserServiceV1.class);
resources.add(ApplicationBean.class);
resources.add(CorsFilterProvider.class);
return resources;
}
}

EDIT: changed code details in the question and title
EJB 3.1 implies a Java EE 6 container implementation.
Java EE 6 implies JAX-RS 1.1.
JAX-RS 1.1 is only required to support #EJB injection of enterprise java beans.
JAX-RS 2.0 as provided in a Java EE 7 implementation supports #Inject for EJBs.
As Steve C answered, the proper way to inject an EJB in JAX-RS 1.1 is with the javax.ejb.EJB annotation. The REST service must also be an EJB for this to work. As such, you have to use the javax.ejb.Stateless annotation instead of javax.enterprise.context.RequestScoped.
The end result is as follows:
#Stateless
#Path("user/v1")
public class UserServiceV1 implements SystemLogger {
#EJB
private ApplicationBean appBean;
//etc.
}
EDIT
Your updated code doesn't deploy. Either have ApplicationBean implement ApplicationBeanLocal and inject the interface, or don't implement it and inject the class directly. With that corrected, I managed to run your example just fine.
Also, in ApplicationService, you don't need to add ApplicationBean.class. You only register there REST root resources and feature providers. #Local is also unnecessary in the UserServiceV1 class, it's not an EJB.
Furthermore, it's beans.xml, not bean.xml (but this file is not necessary anymore from CDI 1.1 on).

I'm beginning Java EE with NetBeans 8.1, Glassfish 4.1 and Apache Derby (included in GlassFish).
For this purpose I'm calling to put and store a car data with its attributes.
But this simple facade always returns "java.lang.IllegalStateException" whereas I'm seeing no mistakes in my Class files.
Here is the very simple Entity of model.car with basic getters and setters :
#Entity
#Table(name = "car")
public class Car implements java.io.Serializable {
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE)
private Integer id;
private String brand;
private String model;
private String year;
private String energy;
private String hp;
private String tp;
private byte[] picture;
Here is the "Facade" for this Entity to store data in Apache Derby :
#Stateless
public class CarFacade extends AbstractFacade<Car> {
#PersistenceContext(unitName = "CarLocPU")
private EntityManager em;
#Override
protected EntityManager getEntityManager() {
return em;
}
public CarFacade() {
super(Car.class);
}
}
I'm having a lot of trouble debugging the following exception since it is very simple short part of code and everything should works fine. Moreover, the StackTrace doesn't show the breaking point like in Java SE.
Here is the exception StackTrace :

Thank you in advance for you help.
EDIT :
Here is the structure of the project.
And here is the persistence.xml content, the application is named "CarLoc".

If you are using JPA outside of the EJB container, you need to declare a JPA <provider> in your persistence.xml.
By default Glassfish uses EclipseLink as the JPA provider. Assuming you don't want to change this, you will want to change your persistence.xml to declare EclipseLink as the JPA provider:
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">

The Session Bean class is:
#Stateless(name="UniversidadJpa")
#Remote(IGestionUniversidad.class)
public class UniversidadServiceEJB {
#Resource
private UserTransaction utx;
#PersistenceUnit(unitName="ApplicationEJBPU")
EntityManagerFactory emf;
public void create(Universidad universidad) throws Exception {
try {
UniversidadJpaController universidadController = new UniversidadJpaController(utx,emf);
universidadController.create(universidad);
} catch (RollbackFailureException ex) {
Logger.getLogger(UniversidadServiceEJB.class.getName()).log(Level.SEVERE, null, ex);
} catch (Exception ex) {
Logger.getLogger(UniversidadServiceEJB.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
And the jpacontroller class is:
public class UniversidadJpaController implements Serializable {
public UniversidadJpaController(UserTransaction utx, EntityManagerFactory emf) {
this.utx = utx;
this.emf = emf;
}
private UserTransaction utx = null;
private EntityManagerFactory emf = null;
public EntityManager getEntityManager() {
return emf.createEntityManager();
}
public void create(Universidad universidad) throws RollbackFailureException, Exception {
if (universidad.getEstudiantes() == null) {
universidad.setEstudiantes(new ArrayList<Estudiante>());
}
EntityManager em = null;
try {
utx.begin();
em = getEntityManager();
List<Estudiante> attachedEstudiantes = new ArrayList<Estudiante>();
for (Estudiante estudiantesEstudianteToAttach : universidad.getEstudiantes()) {
estudiantesEstudianteToAttach = em.getReference(estudiantesEstudianteToAttach.getClass(), estudiantesEstudianteToAttach.getId());
attachedEstudiantes.add(estudiantesEstudianteToAttach);
}
universidad.setEstudiantes(attachedEstudiantes);
em.persist(universidad);
for (Estudiante estudiantesEstudiante : universidad.getEstudiantes()) {
Universidad oldUniversidadOfEstudiantesEstudiante = estudiantesEstudiante.getUniversidad();
estudiantesEstudiante.setUniversidad(universidad);
estudiantesEstudiante = em.merge(estudiantesEstudiante);
if (oldUniversidadOfEstudiantesEstudiante != null) {
oldUniversidadOfEstudiantesEstudiante.getEstudiantes().remove(estudiantesEstudiante);
oldUniversidadOfEstudiantesEstudiante = em.merge(oldUniversidadOfEstudiantesEstudiante);
}
}
utx.commit();
} catch (Exception ex) {
// try {
// utx.rollback();
// } catch (Exception re) {
// throw new RollbackFailureException("An error occurred attempting to roll back the transaction.", re);
// }
throw ex;
} finally {
if (em != null) {
em.close();
}
}
}
}
And the Persistence Unit is:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="ApplicationEJBPU" transaction-type="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>sqlServer</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="eclipselink.ddl-generation" value="create-tables"/>
</properties>
</persistence-unit>
</persistence>
Please what is the problem?..
Thank you very much...
Usually in an EJB Environment, the transaction is managed by the the container. It wraps the Bean methods in transactions with automatic rollback when an exception occurs. This also means that manually starting/committing/rollback a Transaction is not allowed and throws an IllegalStateException.
Reference: http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/Transaction3.html
As posted above, under a Container Managed Transaction (CMT) you will get the getStatus() exception if you use the API.
https://issues.jboss.org/browse/JBSEAM-456
But you can as an alternative use:
#Resource
TransactionSynchronizationRegistry
How to tell if a transaction is active in a Java EE 6 interceptor?
By the way - the getStatus() api blows on glassfish, but it does not blow up on weblogic 12.1.2.
Weblogic should actually be throwing the exception on the get status api.
The
#Resource
TransactionSynchronizationRegistry
Works fine on both containers.
