In my Hibernate application, I am using persistence.xml as

<?xml version="1.0" encoding="UTF-8"?>

<persistence xmlns="https://jakarta.ee/xml/ns/persistence"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="https://jakarta.ee/xml/ns/persistence

https://jakarta.ee/xml/ns/persistence/persistence_3_0.xsd"

version="3.0">

<persistence-unit name="com.myproject">

<description>My Project</description>

<provider>org.hibernate.ejb.HibernatePersistence</provider>

<class>com.myproject.entity.User</class>

<properties>

<property name="hibernate.dialect"

value="org.hibernate.dialect.MySQLDialect" />

<property name="jakarta.persistence.jdbc.driver"

value="com.mysql.jdbc.Driver" />

<property name="jakarta.persistence.jdbc.url"

value="jdbc:mysql://localhost/myproject" />

<property name="jakarta.persistence.jdbc.user" value="root" />

<property name="jakarta.persistence.jdbc.password"

value="abcd" />

</properties>

</persistence-unit>

</persistence>

When I run the application, I am getting the error.

Caused by: jakarta.persistence.PersistenceException: No Persistence provider for EntityManager named com.myproject

Check for following points.

1. The location of persistence.xml should be <classpath>/META-INF/persistence.xml

2. Hibernate dependencies should be resolved.

<dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-core</artifactId>
   <version>6.1.6.Final</version>
</dependency>
<dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-entitymanager</artifactId>
   <version>5.6.14.Final</version>
</dependency>

3. In the Hibernate version 4.3 and above, org.hibernate.ejb.HibernatePersistence has been replaced by org.hibernate.jpa.HibernatePersistenceProvider .

Use following line in persistence.xml

<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

Thanks. Issue is resolved. I replaced org.hibernate.ejb.HibernatePersistence by org.hibernate.jpa.HibernatePersistenceProvider and it worked.
