You must configure the hbm2ddl.auto in the hibernate configuration file :

<property name="hbm2ddl.auto">create</property>

after run 1 time the app .

and change it to update , like this :

<property name="hbm2ddl.auto">update</property>

The problem is you have some old values inserted in the table and when you want to change the schema , there is no default value for those old values .
