Cannot generate database schemas from model @Entity classes in GlassFish 5 server using MySQL

Ppyyt :

Hello I have got problem with enabling auto generating database tables from java models @Entity classes. I have tried almost everything.

I have created maven project in Intellij Idea at first I have downloaded JavaEE 8 api implementation which I am using.

I am using Glassfish 5.0 server as a java ee 8 implementation provider and MySQL database.

My Project structure:

My pom.xml looks like:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

My model @Entity class wchich I want to generate tables in my MySQL database.

package model;

import javax.persistence.*;
@Entity
@TableGenerator(name = "USER")
public class User {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "USERID")
private int userId;
@Column(name = "USERNAME")
private String username;
@Column(name = "PASSWORD")
private String password;
@Column(name = "EMAIL")
private String email;

public User(String username, String password, String email) {
    this.username = username;
    this.password = password;
    this.email = email;
}

public User() {
}

public int getUserId() {
    return userId;
}

public void setUserId(int userId) {
    this.userId = userId;
}

public String getUsername() {
    return username;
}

public void setUsername(String username) {
    this.username = username;
}

public String getPassword() {
    return password;
}

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

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}
}

My persistence.xml file src/main/java/META-INF/ looks like:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
 <persistence 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_2.xsd"
         version="2.2">

<persistence-unit name="myPu" transaction-type="JTA">
    <jta-data-source>jdbc/PlanYourTime</jta-data-source>
    <properties>
        <property name="javax.persistence.schema-generation.database.action" value="create"/>
        <property name="javax.persistence.schema-generation.create-source" value="metadata"/>
        <property name="javax.persistence.schema-generation.drop-source" value="metadata"/>
        <property name="javax.persistence.sql-load-script-source" value="META-INF/load-script.sql"/>
        <property name="eclipselink.logging.level" value="FINE"/>
        <property name="eclipselink.ddl-generation" value="create-or-extend-tables"/>
    </properties>
</persistence-unit>

And in my glassfish server admin page I have also added Jdbc resourcure and jdbc connection pool like this:

And my war artifact structure looks like in IntellijIdea which I deploy to glassfish 5.0 server:

When i was checking server.log for glassfish I don't get any errors.

I will be very thankful for every help.

Did you created/used entity manager? If not, persistence module did not start. Make a insert using entity manager, or try:

Use eclipselink.deploy-on-startup to configure deployment on startup (at the creation of the EntityManagerFactory) instead of occurring the first time an EntityManager is created.
