[FIXED] An error is displayed saying "NoClassDefFoundError: javax/persistence/Entity" when using tomcat 10 with hibernate 5.6

Issue

I have java project (version 8)

I upgraded my hibernate version from 5.0.3.Final to 5.6.9.Final

   <dependency>
                <groupId>org.hibernate</groupId>
                <artifactId>hibernate-core</artifactId>
                <version>5.6.9.Final</version>
            </dependency>
            <dependency>
                <groupId>org.hibernate</groupId>
                <artifactId>hibernate-entitymanager</artifactId>
                <version>5.6.9.Final</version>
            </dependency>

I tried to run my tomcat (version 10.0.20) after upgrading the hibernate version and I received the next error:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [spring/db-config.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: javax/persistence/Entity (wrong name: jakarta/persistence/Entity)

The sessionFactory bean looks like that:

  <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"
          depends-on="flyway">
        <property name="dataSource" ref="itpDataSource"/>
        <property name="packagesToScan" value="com.imperva.itp.domain,com.imperva.itp.commons.domain"/>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.PostgresPlusDialect</prop>
                <prop key="configurationClass">org.hibernate.cfg.Configuration</prop>
                <prop key="hibernate.show_sql">false</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.id.new_generator_mappings">true</prop>
                <prop key="hibernate.default_schema">${itp.db.username}</prop>
            </props>
        </property>
    </bean>

I don't know if it is relevant but my Spring version is 4.3.30.RELEASE

after running different combinations:

hibernate 5.0.3.Final with tomcat 8: works properly
hibernate 5.0.3.Final with tomcat 10: works properly
hibernate 5.6.9.Final with tomcat 8: works properly
hibernate 5.6.9.Final with tomcat 10: doesn't work and the exception is thrown 

any ideas?

Solution

in the end I upgraded the spring to 5.3.20 and spring web to 5.7.1 and I changed all the references of javax.persistence to jakarta.persistence and it worked. I kept the hibernate version 5.6.9.Final and tomcat 10
