java - Hibernate 3 - MappingException - AnnotationConfiguration instance is required to use <mapping class="xxxxclass"/> -

i tried hand @ writing simple hibernate 3 java program - fetch data db, works fine when try configure hbm.xml file when use model class configure same, face issues below. ie

<mapping class="example.pojo_stock"/>   

instead of

<mapping resource="pojo_stock.hbm.xml" /> 

although tried related queries on stackoverflow (many marked duplicate) unable find solution. kindly help

public class mainapp {      private static sessionfactory factory;      public static void main(string[] args) {         try{             system.out.println("in main method of mainapp...");              configuration configure=new configuration();               configure.configure("hibernate.cfg.xml");             factory = configure.buildsessionfactory();              mainapp mainapp = new mainapp();             mainapp.listdetails_stock();         }         catch(throwable ex){              system.err.println("failed create sessionfactory object." + ex);             throw new exceptionininitializererror(ex);           }     }      public void listdetails_stock(){         system.out.println("in listdetails_stock method of mainapp...");          session session = factory.opensession();         transaction tx = null;          try{             tx = session.begintransaction();             list<pojo_stock> details = session.createquery("from pojo_stock").list();             for(pojo_stock detail : details){                 system.out.print("\nstockid: " + detail.getstockid());                 system.out.print("\nstockcode: " + detail.getstockcode());                 system.out.print("\nstockname: " + detail.getstockname());             }             tx.commit();         }           catch (hibernateexception e) {             if (tx!=null) tx.rollback();             e.printstacktrace();          }finally {             session.close();          }     } 

the model class looks like

@entity @table(name = "stock") public class pojo_stock {      int stockid;         string stockcode;     string stockname;      // getters & setters     } 

and hibernate config looks below,

    <property name="hibernate.dialect">         org.hibernate.dialect.oracledialect     </property>     <property name="hibernate.connection.driver_class">         oracle.jdbc.driver.oracledriver     </property>      <property name="hibernate.connection.url">         jdbc:oracle:thin:@xxxx     </property>     <property name="hibernate.connection.username">         xxxx     </property>     <property name="hibernate.connection.password">         xxxx     </property>     <property name="show_sql">true</property>      <!-- list of xml mapping files -->     <!--  <mapping resource="pojo_stock.hbm.xml" /> -->     <mapping class="example.pojo_stock"/>  </session-factory> 

the error on console below,

failed create sessionfactory object.org.hibernate.mappingexception: annotationconfiguration instance required use <mapping class="example.pojo_stock"/> exception in thread "main" java.lang.exceptionininitializererror     @ example.mainapp.main(mainapp.java:28) caused by: org.hibernate.mappingexception: annotationconfiguration instance required use <mapping class="example.pojo_stock"/>     @ org.hibernate.cfg.configuration.parsemappingelement(configuration.java:1524)     @ org.hibernate.cfg.configuration.parsesessionfactory(configuration.java:1479)     @ org.hibernate.cfg.configuration.doconfigure(configuration.java:1458)     @ org.hibernate.cfg.configuration.doconfigure(configuration.java:1432)     @ org.hibernate.cfg.configuration.configure(configuration.java:1352)     @ tutorialspoint.example.mainapp.main(mainapp.java:19) 

i tried use annotationconfiguration() instead of configuration() not work instead throws below error,

i think there issue .jar files. not using latest .jars. trying annotational configuration in pojo.

@entity @table(name = "stock") public class pojo_stock {      int stockid;         string stockcode;     string stockname;      // getters & setters     } 

so, first please use annotationconfiguration() instead of configuration(); have tried this.

so, think (possibly) using incompatible versions of hibernate core , annotations. 1 of possible combination hibernate core 3.3.2 hibernate annotations 3.4 , try. have @ compatibility matrix here more details.
