Using JPA in JavaFX environment - mysql

Question

I'm trying to use JPA for handling persistence logic. For this I need, I suppose, persistence.xml, which looks like this:
<persistence 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"
version="2.0">
<persistence-unit name="BookKeeperUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<properties>
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/Gamer"/>
<property name="hibernate.connection.username" value="UserName"/>
<property name="hibernate.connection.password" value="password"/>
<property name="hibernate.archive.autodetection" value="class" />
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
</properties>
</persistence-unit>
</persistence>
then I need to import hibernate-entitymanager:4.3.5.Final to my library(using Intellij Idea as IDE) and the mysql driver. Which I also have done.
This is my entity class:
#Entity
#Table(name = "application_user")
public class ApplicationUser {
private String userName;
private String name;
private String passwordhHash;
#Id
#Column(name = "user_name")
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
#Column(name = "name_of_user")
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#Column(name = "password_hash")
public String getPasswordhHash() {
return passwordhHash;
}
public void setPasswordhHash(String passwordhHash) {
this.passwordhHash = passwordhHash;
}
}
and the DAO class:
public class TestEntityManager {
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("BookKeeperUnit");
EntityManager em = entityManagerFactory.createEntityManager();
public ApplicationUser getAppUserByUserName(String userName){
em.getTransaction().begin();
ApplicationUser appUser = em.find(ApplicationUser.class, userName);
em.getTransaction().commit();
em.close();
entityManagerFactory.close();
return appUser;
}
}
But I get an error that I don't really understand:

So how can I resolve the error?
java.lang.NoSuchMethodError: javax.persistence.Table.indexes()[Ljavax/persistence/Index;

Answer 1

Wow, after 3 days working on it I finally solved the problem. The main problem was that I was using the library hibernate-entitymanager:4.3.5.Final with java persistence API 2.0 instead of using it with hibernate-entitymanager:4.2.8.Final. I hope this will help others who may have same problem.
