java - Hibernate mapping error - Unknown entity -

i'm hibernate newbie , im receiving error when trying persist object -

error -->unknown entity: org.apache.struts.register.model.event

in hibernate.cfg.xml, define mapping as,

<mapping class="org.apache.struts.register.model.event"/>

my event class -

package org.apache.struts.register.model;  import org.hibernate.annotations.entity;   import javax.persistence.generationtype; import javax.persistence.id; import javax.persistence.generatedvalue; import javax.persistence.table;  @entity @table (name="event")  public class event {      @id     @generatedvalue ( strategy =  generationtype.auto)  private int eventid;  private string eventname;  private string eventdescription;   public string geteventname() {   return eventname;  }   public void seteventname(string eventname) {   this.eventname = eventname;  }   public string geteventdescription() {   return eventdescription;  }   public void seteventdescription(string eventdescription) {   this.eventdescription = eventdescription;  }   public string tostring(){   return this.eventname + "," + this.eventdescription;  }  } 

eventdao -

package dao;   import org.apache.struts.register.model.event; import org.hibernate.session; import org.hibernate.sessionfactory; import org.hibernate.transaction;   public class eventdao {      public static boolean registerevent(event u) {           sessionfactory sf = hibernateutil.getsessionfactory();          transaction t = null;          try  {          session s  = sf.opensession();          t = s.begintransaction(); // start new transaction          s.persist(u);          t.commit();  // commit transaction           return true;          }          catch(exception ex) {              system.err.println("error -->"  + ex.getmessage());              if ( t!=null) t.rollback();  // rollback transaction on exception               return false;          }     } } 

system.err.println("error -->" + ex.getmessage()), line throws exception.

thanks.

import org.hibernate.annotations.entity; 

the hibernate @entity not enough entity discovered. use javax.persistence.entity instead.

see here:

@javax.persistence.entity still mandatory, @org.hibernate.annotations.entity not replacement.
