I can't find resolve PersistenceException: No Persistence provider for EntityManager

I found some solutions in the forum, but they not working for me.
The problem is that when I run main method I receive this exception - image


PersistenceException: No Persistence provider for EntityManager


On the imane is my persistance.xml file pat but it's not working. I try to change file path to web/WEB-INF/classes/META-INF, but its's still not working.

Here my full persistance.xml source

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

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" version="2.1">

<persistence-unit name="StudentPU">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.classes.StudentBean</class>
<properties>
<property name="hibernate.connection.url" value="jdbc:h2:tcp://localhost/~/Students"/>
<property name="hibernate.connection.driver_class" value="org.h2.Driver"/>
<property name="hibernate.connection.username" value="doncho"/>
<property name="hibernate.connection.password" value=""/>
<property name="hibernate.archive.autodetection" value="class"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="true"/>
<property name="hbm2ddl.auto" value="update"/>
<property name="hibernate.temp.use_jdbc_metadata_defaults"
value="false" />
<property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect" />
</properties>
</persistence-unit>
</persistence>


And one more thing? Why HibernatePersistence is stricken?
I resolve "stricken" mistake like that - image
Is it correct?
But anyway the PersistenceException: No Persistence provider for EntityManager still there.

I tryed - this and this - nothings happened

I would be grateful for any ideas to resolve this error because @Entity method is important to me.

Best regards,

Answer

The workig method for me is to create this path in my project tree: web/WEB-INF/classes/META-INF/persistence.xml

This is working path when We create Web Applications with IntelliJ.
