Concurrency issue

Hi,

I am working on J2EE application and using Hibernate.

Application is online submission form which contains questions. User has to respond to each question. when user fills the response and click on save. Responses will be stored into response table.

Now i am having problem with one user's record as there are three entries for each question in the response table.User used the application only once and submitted the response only once.

Please suggest me what could be the possible reason.
