thanks to u , i got it right this time ... 

and thought of describing the method i followed for the help of any other , who might need this in the future..

what i did was i add the following property to persistence.xml
   <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" /> 

also , as u said , 
    <property name="hibernate.hbm2ddl.auto" value="update"/> 

so this works fine.Even i restart the JBOSS server , the table is persistent in the database..

But , if i used 
 <property name="hibernate.hbm2ddl.auto" value="create-drop"/> 
instead. ( which i tested by using it earlier ) and , when the JBOSS restarted the table will be created from the beginning , when the JBOSS is shutdown , the table is vanished.
