I am creating a login, using JSP, Servlet and Hibernate. Please help me resol

My POJO class for User is:

@Entity
@Table(name = "Users")
public class User implements Serializable {

    private static final long serialVersionUID = 1986328586398921108L;

    @Id
    @GeneratedValue
    @Column(name="ID")
    private Long id;

    @NotNull
    @Column(name="NAME", unique = true)
    private String name;


    @NotNull
    @Column(name="PASSWORD")
    private String password;

    public User() {}

    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

Corresponding MySQL database table is:

create table Users (
    ID bigint not null auto_increment primary key,
    NAME varchar(20) not null unique,
    PASSWORD varchar(20) not null
);

hibernate.cfg.xml (placed in src folder)

<!DOCTYPE hibernate-configuration
    PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>

        <!-- hibernate dialect -->

        <!-- Name the annotated User class -->
        <mapping class = "pojo.User"/>

    </session-factory>
</hibernate-configuration>

Please also comment is it beneficial to serialize class. Thanks in advance!

Edit 1: Class, I'm initializing SessionFactory within:

public class HibernateUtil {

    private static final SessionFactory sessionFactory;
    static {
        try {
            Configuration configuration = new Configuration();
            configuration.configure();
            ServiceRegistry serviceRegistry = new ServiceRegistryBuilder()
                                                .applySettings(configuration.getProperties())
                                                .buildServiceRegistry();
            sessionFactory = configuration.buildSessionFactory(serviceRegistry);
        } catch (Throwable e) {
            System.err.println("Initializing session factory failed: " + e);
            throw new ExceptionInInitializerError(e);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}

I encountered this error after upgrading from JDK 8 to JDK 11. In my case, different tricks in pom (with dependencies like javassist) did not help.
The solution was simply to upgrade Hibernate from 5.2.x to 5.4.x (or higher), as from this version suport for JDK 11 is provided out of the box (according to official announcement).

Instead of

This problem may occur with jdk-11 sometimes.

Following dependency can resolve it.

<dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.23.1-GA</version>
</dependency>

I experienced this issue working with Hibernate version 5.2.17. Switching to 5.3.7 worked fine.

I had the same problem, them followed the answer of Vitalii Supryhan and i added:

<dependency>
    <groupId>javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.12.1.GA</version>
</dependency>

In the pom.xml file, updated the maven project (clicking right button upon the project->maven->update project)

And the problem it was resolved!! Thanks!

Had such problem. The solution was to add dependency: javassist-x.xx.x-y.jar from hibernate distribution
