I'm new to spring. I.m learning spring from javapoint. After learning some basics of spring from javapoint and spring docs, I moved towards learning hibernate with spring, but in very first try (example), I stucked with the expception: NoClassDefFoundExpetion: javax/persistence/PersistenceContext. To resolve this exception, I've googled and looked for similar kind of situations (and their solutions) on this and this, but nothing helps me.
Here is the full stacktrace: of my exception
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.annotation.internalPersistenceAnnotationProcessor': Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/persistence/PersistenceContext

I'm using eclipse-neon IDE, spring-framework 4.3.2 RELEASE, Hibernate-5.2.2 Final and Oracle 10G(database).There is a STUDENT table in my database having 4-5 entries. Also I've written thespring code using simple (console base) java project and NOT using any build tool. Here is my complete code and libraries list which I'm currently using:
Student.java
public class Student {
private Integer rollNo;
private String name;
/**
* @param rollNo
* @param name
*/
public Student(Integer rollNo, String name) {
super();
this.rollNo = rollNo;
this.name = name;
}
//Getter and setter ....
StudentDAO.java
public class StudentDAO {
private HibernateTemplate hibernateTemplate;
public StudentDAO(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
public void setHibernateTemplate(HibernateTemplate template) {
this.hibernateTemplate = template;
}
public void saveStudent(Student student) {
hibernateTemplate.save(student);
}
public List<Student> readAll() {
return hibernateTemplate.loadAll(Student.class);
}
}
I'm using java annotation based configuration, So my AppConfig.java is:
@Configuration
public class AppConfig {
@Bean
public DriverManagerDataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource("jdbc:oracle:thin:@localhost:1521/xe", "user", "password");
dataSource.setDriverClassName("oracle.jdbc.driver.OracleDriver");
return dataSource;
}
@Bean
public LocalSessionFactoryBean sessionFactoryBean() {
LocalSessionFactoryBean bean = new LocalSessionFactoryBean();
bean.setDataSource(dataSource());
bean.setMappingResources("xml/student.hbm.xml");
Properties prop = new Properties();
prop.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle9Dialect");
prop.setProperty("hibernate.hbm2ddl.auto", "update");
prop.setProperty("hibernate.show_sql", "true");
bean.setHibernateProperties(prop);
return bean;
}
@Bean
public HibernateTemplate hibernateTemplate() {
HibernateTemplate template = new HibernateTemplate((SessionFactory) sessionFactoryBean());
return template;
}
@Bean
public StudentDAO DAO() {
return new StudentDAO(hibernateTemplate());
}
}
Student.hbm.xml XML file:
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="bean.Student" table="student">
<rollNo name="rollNo">
<generator class="assigned"></generator>
</rollNo>
<property name="name"></property>
</class>
</hibernate-mapping>
and here is my Main-Method Class
public class Test {
public static void main(String[] args) {
ApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class);
StudentDAO dao = context.getBean(StudentDAO.class);
List<Student> list = dao.readAll();
for(Student s: list)
System.out.println(s);
}
}
here is the list of liberaries (with jar file) which I've included in my project:
SPRING
HIBERNATE
Commons logging and ORALCE 10G Driver
And some other too
How to solve the above mentioned exception, which library I've to add/remove or what else I can try to resolve the issue.
Regret for long question
Example Reference
This example is based on source code, available at javapoint
