Hi All,

actually I have created Entity Beans which are used to create  tables in mysql database, everything is working fine with transaction  classes using entityfactory.

Now I need this functionality...when I deploy the EAR file in  application sever JBOSS..it have to check whether the tables are  existing in the database or not..if they are not present..it have to  create the tables automatically..of course I have specified this  function hibernate.hbm2ddl.auto=update in persistence.xml..but still not  creating any tables which are not present in the database and not  throwing any error also when ever I run the application server its creating only mysql default tables..but not the developed ones and here I am give my code:

package com.ernst.persistenceImpl.beanImpl;

    public void setDesc(String desc) {

Can any one please give me an idea how to do this or please tell me if I have done anything wrong in above files.

Thanks in Advance.
