    Hibernate Annotations doesnt work if i dont declare the mapping class

    Fatih Söylemez Newbie
      Hello,

      My problem is ,my hibernate annotations doesnt work(says unknown entity) if
      i dont define the entity classes in the hibernate.cfg.xml file with putting
      a line like                    
      "<mapping class="domain.view.MenuCategory"></mapping>".
      What can i do to fully get use of annotations?



      My components.xml file has the following lines.

          <persistence:hibernate-session-factory name="hibernateSessionFactory" />
              <persistence:managed-hibernate-session name="sessionHibernate" auto-create="true" session-factory-jndi-name="myfactory"/>



      And this is my hibernatecfg.xml file.


      <?xml version="1.0" encoding="utf-8"?>
      <!DOCTYPE hibernate-configuration PUBLIC
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
      "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
      <hibernate-configuration>

          <session-factory name="myfactory">

      <property name="current_session_context_class">thread</property>
      <propertyname="hibernate.bytecode.use_reflection_optimizer">false</property><property name="show_sql">true</property>
      <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
      <property name="hibernate.connection.datasource">java:comp/env/jdbc/testdatasource</property>
      <property name="hibernate.format_sql">true</property>
      <property name="hbm2dll.auto">create-drop</property>
      <property name="cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
      <property name="transaction.flush.before_completion">true</property>
      <property name="connection.release_mode">after_statement</property>

          </session-factory>
      </hibernate-configuration>


      And my context.xml files is as follows.


      <Context path="/DBTest" docBase="DBTest"
      debug="5" reloadable="true" crossContext="true">


      <Resource name="jdbc/testdatasource" auth="Container" type="javax.sql.DataSource"
      maxActive="100" maxIdle="30" maxWait="10000"
      username="root" password="" driverClassName="com.mysql.jdbc.Driver"
      url="jdbc:mysql://localhost/hacivad"/>
      </Context>



      and the class is,


      package domain.view;

      import java.io.Serializable;

      import javax.persistence.Column;
      import javax.persistence.Entity;
      import javax.persistence.Id;
      import javax.persistence.Table;

      @SuppressWarnings("serial")
      @Entity
      @Table(name = "VIEW_MENU_CATEGORY")
      public class MenuCategory implements Serializable {

              @Id
              @Column(name = "ID")
              private Long id;
             
              @Column(name = "CATEGORY_LABEL")
              private String label;
             
              @Column(name = "KEY")
              private String key;
             

              public Long getId() {
                      return id;
              }

              public String getLabel() {
                      return label;
              }

              public String getKey() {
                      return key;
              }

      }



      thanks for the help.

          Are the entities in the same jar as the persistence.xml?

            yes,but i dont reference it from components.xml file.Because i dont want to use an EntityManager(surely there is something wrong with my logic).I will share my components.xml file and persistence.xml file so we can figure out what the problem is more easily.


            persistence.xml(not so diff. from the example project,just the datasource)

            And this is how i get the hibernateSession from the context in the DAO class.


                    @In("sessionHibernate")
                    private Session session;




            By the way, isnt persistence.xml is some kind of needless here,because i have all this information in hibernate.cfg.xml file.
