ClassNotFoundException for HibernatePersistenceProvider

Tags: , , , ,



I have a JSF project which builds perfectly with java 7, but when I try to deploy the WAR in Jboss Application Server, I’m getting the bellow error.

The persistance.xml looks like bellow

The bellow dependencies are included in the pom

        </dependency>

The JBoss version is 7.1.1 Final

What am I doing wrong here?

Answer

The issue here was the conflict between the Hibernate jars in JBoss modules and my project. When I use the JBoss latest one(WildFly 20), the issue went away. Note that I had to copy the MySQL connector jar into WildFly deployments dir and add the following datasource to my project.

<datasources xmlns="http://www.jboss.org/ironjacamar/schema">
    <datasource jndi-name="MySQLDS" pool-name="MySQLPool">
        <connection-url>jdbc:mysql://localhost:3306/db</connection-url>
        <driver>mysql-connector-java-8.0.21.jar</driver>
        <pool>
            <max-pool-size>30</max-pool-size>
        </pool>
        <security>
            <user-name>username</user-name>
            <password>password</password>
        </security>
    </datasource>
</datasources>
