Hi All,

I am trying to integrate vaadin with hibernate and spring. Data is getting persisted for the first time when I run my application. But second time when I run the application, data gets deleted from DB(mysql) table. Please help me to solve the issue.

Following is all related code:-

Domain class user



DaoImpl class


Spring config. file(applicationContext class)


Vaadin main class


Please provide some input to solve this issue.I am using hibernate version 3.6.0 and Spring version 3.0.4 and MySQL as Database.

Regards,
Vikram
