I'm making a Restful web service using netbeans, tomcat, jpa and jax-rs. I have this error since I've add the <class /> tags to my persistence.xml for all of my classes (And I need them to make a select).
The error is : https://gist.github.com/anonymous/bb37c28cdb3dbdf721c5206bfa6369c3
And my persistence.xml is :
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

And this is the main dao (that worked before, didn't change anything) but without all the CRUD methods (just the read for example)
package dao;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.persistence.PersistenceContext;
public class MainDAO<T> implements IMainDAO<T> {
protected Class<T> clazz;
private final EntityManagerFactory factory;
private static final String PERSISTENCE_UNIT_NAME = "NataRestServicePU";
#PersistenceContext(unitName = "NataRestServicePU")
protected EntityManager entityManager;
public MainDAO(Class<T> type){
clazz = type;
factory = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME);
}
public void setClazz(Class<T> clazzToSet) {
this.clazz = clazzToSet;
}
#Override
public T read(int id){
try{
newEntityManager();
return entityManager.find(clazz,id);
}finally{
closeEntityManager();
}
}
protected void closeEntityManager(){
entityManager.close();
}
protected void newEntityManager(){
entityManager = factory.createEntityManager();
}
}
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".
<?xml version="1.0" encoding="UTF-8"?>

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">
<persistence-unit name="CarLocPU" transaction-type="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

i'm working on a spring web application using spring data jpa lately
i have problems with the persistence configuration :
#Configuration
#EnableTransactionManagement
#ComponentScan(basePackages = "com.servmed")
#PropertySource({ "/resources/hibernate.properties" })
#EnableJpaRepositories(basePackages = "com.servmed.repositories")
public class PersistenceConfig {
#Autowired
private Environment env;
Properties jpaProperties() {
return new Properties() {
{
setProperty("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
setProperty("hibernate.dialect", env.getProperty("hibernate.dialect")); //allows Hibernate to generate SQL optimized for a particular relational database.
setProperty("hibernate.show_sql",env.getProperty("hibernate.show_sql"));
}
};
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory()
{
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl(true);
vendorAdapter.setShowSql(true);
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setDataSource(dataSource());
factory.setJpaVendorAdapter(vendorAdapter);
factory.setJpaProperties(jpaProperties());
factory.setPackagesToScan("com.servmed.models");
//factory.setLoadTimeWeaver(new InstrumentationLoadTimeWeaver());
return factory;
}
#Bean

dataSource.setUsername(env.getProperty("jdbc.user"));
dataSource.setPassword(env.getProperty("jdbc.pass"));
return dataSource;
}
}
i get this error and i can't seem to find what's wrong :
Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [com/servmed/configuration/PersistenceConfig.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory]]
PS: i noticed that the hibernate entity manger i added to libraries is depecated , should i replace with something else ?
Not entirely sure what the problem is but I believe your entity manager definition might be busted somewhere.
I use this definition that is pretty close to your. Have a look.
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
emf.setDataSource(this.dataSource());
emf.setPackagesToScan("com.servmed.models");

HibernateJpaVendorAdapter va = new HibernateJpaVendorAdapter();
emf.setJpaVendorAdapter(va);

Can anybody let me know the root cause of this error?
It looks as though you've missed the #Autowired annotation in your controller.
Try:
#Controller
public class LoginController {
private MongoTemplate mongoTemplate;
#Autowired
public void setMongoTemplate(MongoTemplate mongoTemplate) {
this.mongoTemplate = mongoTemplate;
}
Or autowire the field directly:
#Controller
public class LoginController {
#Autowired
private MongoTemplate mongoTemplate;
With this persistence.xml:

I get
[EL Warning]: 2012-04-17 15:08:18.476--The collection of metamodel types is empty. Model classes may not have been found during entity search for Java SE and some Java EE container managed persistence units. Please verify that your entity classes are referenced in persistence.xml using either <class> elements or a global <exclude-unlisted-classes>false</exclude-unlisted-classes> element
After replacing <exclude-unlisted-classes>false</exclude-unlisted-classes> with a lot of <class> elements, the problem can be fixed, but I'd prefer not to have to remember to edit persistence.xml every time I need to add a new entity or remove an old one. Why doesn't the version with <exclude-unlisted-classes> work?
I had faced similar situation
If I generate JPA metamodel, copy paste it in correct pacakge and check it in to svn, and disable metamodel generation, all junit tests were fine
if i generate metamodel with every build, at junit time - embedded glassfish will find all ejb and metamodel fine, but non ejb junit will fail
I had to do this in my src/test/resources/META-INF/persistence.xml
