Spring jpa(Hibernate) with tomcat - spring

Question

I'm working with JPA(Hibernate) and spring project these days, I configured spring, jpa and try to deploy the application on tomcat7, As I know jpa/hibernate creates tables using entity class first loading, but here I couldn't see any connection between database and application when applications starts, below you can see my configuration,I have seen lot of questions posted regarding this matter, I couldn't find the proper solution to my problem.
Can any one tell me what is the problem here.I have created a application without any issues in jetty server sometime back,
Thank you in advance

Answer 1

I think there is no issue with your configuration, try after removing "default-lazy-init=true" attribute
Cheers

Answer 2

try changing:
<property name="hibernate.hbm2ddl.auto" value="validate"/>
to:
<property name="hibernate.hbm2ddl.auto" value="update"/>
or:
<property name="hibernate.hbm2ddl.auto" value="create"/>
