directory structure please ignore hibernate.cfg.xml file, tried using hibernate sessionfactory , ran major error couldn't solve , said hell it. plus post says jpa preferred

here needed jar files

here persistence.xml file

entitymanagerfactory

public class databaseutil {      private static entitymanagerfactory sessionfactory = buildsessionfactory();      private static entitymanagerfactory buildsessionfactory() {         try {             if (sessionfactory == null) {                 sessionfactory = persistence.createentitymanagerfactory("org.hibernate.ejb.hibernatepersistence");             }             return sessionfactory;         } catch (throwable ex) {             system.err.println("initial entitymanagerfactory creation failed." + ex);             throw new exceptionininitializererror(ex);         }     }      public static entitymanagerfactory getsessionfactory() {         return sessionfactory;     }      public static void shutdown() {         getsessionfactory().close();     } } 

you using wrong identifier persistence-unit. name of specified here:

...   <persistence-unit name="com.learning.jpa">   ...   </persistence-unit> </persistence> 

the stacktrace tells

no persistence provider entitymanager named org.hibernate.ejb.hibernatepersistence

so need reference pu via it's correct, specified name com.learning.jpa in relevant code snippet so:

if (sessionfactory == null) {     sessionfactory = persistence.createentitymanagerfactory("com.learning.jpa");  } 

having changed correct pu-name should work. hope helps.
