java hibernate jpa

  • You can give us the result of mvn dependency:tree and the contents of pom.xml? (assuming you are using Maven). This problem usually appears when there is something wrong in classpath

  • I am not using Maven

  • Are you with the Hibernate libs right on the project? It shows all the Jars that are on the project then.

  • yes I put the libs of Hibernate. I put the a print of the jars used

Check the version of the Hibernate-Commons-Annotations library that is 4.0.1 while the others are 4.1.6.

Another thing the line:

fr.buscaTodas();

Should be:

listaFornecedor = fr.buscaTodas();
