hbm2hbmxml does not generate hibernate mapping

I have search for this every where but couldnt find the answere i m following this reference and used this as a tutorial to write an ANT task to convert a POJO with ejb 3 annotations to a hibernate mapping file (hmb.xml)

My build ends successfully without errors but i cant found any hbm.xmk inside the target directory or any where

here is the code i used.

build.xml

Please help me there is not much tutorials or working example sample codes for this task specially for generating hbm files from POJO s using annotationsconfiguration

Why would you want to convert from annotations to XML config? Many EJB3 annotations have direct Hibernate equivalents, or actually use the same annotation (javax.persistence.*). I would just set up your project to compile against Hibernate and see what blows up, fix them, and move on. Then you don't need to the XML files.

Ok i have found the reason :D i didnt add mapping to the class in hibernate.cfg.xml file

previously it was

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

<hibernate-configuration>
<session-factory>
  <property name="hibernate.connection.driver_class">
com.mysql.jdbc.Driver</property>

  <property name="hibernate.connection.url">
jdbc:mysql://localhost/hibernatetutorial</property>
  <property name="hibernate.connection.username">root</property>
  <property name="hibernate.connection.password"></property>
  <property name="hibernate.connection.pool_size">1</property>
  <property name="hibernate.session_factory_name">jndi/composite/name</property>
  <property name="show_sql">true</property>
  <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

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

But it should be

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

<hibernate-configuration>
<session-factory>
  <property name="hibernate.connection.driver_class">
com.mysql.jdbc.Driver</property>

  <property name="hibernate.connection.url">
jdbc:mysql://localhost/hibernatetutorial</property>
  <property name="hibernate.connection.username">root</property>
  <property name="hibernate.connection.password"></property>
  <property name="hibernate.connection.pool_size">1</property>
  <property name="hibernate.session_factory_name">jndi/composite/name</property>
  <property name="show_sql">true</property>
  <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

  <!-- Mapping files of the class should go here  -->
  <mapping class="Blog"/>

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

what is missing was "" part now it generate the Blog.hbm.xml file.
