java.lang.ClassNotFoundException: org.hibernate.proxy.EntityNotFoundDelegate

Question

I deploys a web application with JSF, hibernate, tomcat7, JAVA EE 5 and maven. I get an error that I can not solve:

my persitane.xml :

  <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect"/>
  <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
  <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
  <property name="hibernate.connection.username" value="root"/>
  <property name="hibernate.connection.password" value="root"/>
  <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/prosper"/>
  <property name="javax.persistence.validation.mode">none</property>

and in my pom.xml :

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.1.8.Final</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.hibernate.javax.persistence</groupId>
        <artifactId>hibernate-jpa-2.0-api</artifactId>
        <version>1.0.1.Final</version>
    </dependency>

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>4.1.8.Final</version>
    </dependency>

Thx :)

In given pom.xml scope provided is used for hibernate-core dependency. It means that dependency should be provided by runtime environment. Tomcat 7 is not shipped with Hibernate, that's why it does make sense to use scope provided in this context.

Problem is fixed by removing scope. Then we will fall back to default scope, which is compile. It means that dependency is available also in runtime (packed with application as well).
