by way, added these dependencies before starting project :

<dependency>     <groupid>org.springframework</groupid>     <artifactid>spring-orm</artifactid>     <version>${org.springframework-version}</version>     </dependency>      <dependency>     <groupid>org.springframework</groupid>     <artifactid>spring-beans</artifactid>     <version>${org.springframework-version}</version>     </dependency>      <dependency>     <groupid>org.springframework</groupid>     <artifactid>spring-tx</artifactid>     <version>3.2.2.release</version>     </dependency>      <dependency>     <groupid>org.hibernate</groupid>     <artifactid>hibernate-commons-annotations</artifactid>     <version>3.2.0.final</version>     </dependency>      <dependency>     <groupid>org.hibernate</groupid>     <artifactid>hibernate-entitymanager</artifactid>     <version>3.6.0.final</version>     </dependency>      <dependency>     <groupid>org.hibernate</groupid>     <artifactid>hibernate-validator</artifactid>     <version>4.1.0.final</version>     </dependency>      <dependency>     <groupid>org.hibernate.javax.persistence</groupid>     <artifactid>hibernate-jpa-2.0-api</artifactid>     <version>1.0.0.final</version>     </dependency>      <dependency>     <groupid>mysql</groupid>     <artifactid>mysql-connector-java</artifactid>     <version>5.1.6</version>     </dependency>

according 2 links:

http://www.springbyexample.org/examples/jpa-joined-inheritance-jpa-entity-config.html

https://en.wikibooks.org/wiki/java_persistence/inheritance

i think have remove line message class:

private string genre; 

and getter , setter methods, because defined column discriminationcolumn annotation:

@discriminatorcolumn(name="genre",discriminatortype=discriminatortype.string)
