Hibernate Postgres Batch Processing - postgresql-9.1

Question

I am running postgres sql 9.2.1 and for the application I am building I am using Hibernate 4.2.8. I have enabled all the necessary stuffs concerning the batch processing in the hibernate config file. Also in my pojo I am using the GenerationType.SEQUENCE for my ids since I am using POstgres sequence features.
However whenever I am doing bacth update it only executes one request and return this :
o.h.e.j.batch.internal.BatchingBatch - Executing batch size: 1
This is portion of my hibernate config file:
<property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
<property name="hibernate.connection.password">xxx</property>
<property name="hibernate.connection.url">jdbc:postgresql:testdb</property>
<property name="hibernate.connection.username">xxx</property>
<property name="hibernate.dialect">org.hibernate.dialect.PostgreSQL82Dialect</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.current_session_context_class">thread</property>
<property name="hibernate.connection.autocommit">false</property>
<property name="hibernate.transaction.auto_close_session">false</property>
<property name="hibernate.transaction.flush_before_completion">false</property>
<property name="hibernate.default_entity_mode">pojo</property>
<property name="hibernate.jdbc.batch_size">40</property>
<property name="hibernate.cache.use_second_level_cache">false</property>
<property name="hibernate.order_updates">true</property>
<property name="hibernate.jdbc.batch_versioned_data">true</property>
<property name="hibernate.cache.use_query_cache">false</property>
<property name="hibernate.order_inserts">true</property>
Please assist me. I have done many searches so far but I have not come accross any that works for me.
