Is it right? Do you have any code referencing Project directly that could be working with an object still?

As Jeanne said you are calling delete on a transient entity. This means you are trying to delete an entity that is not yet persisted (does not have an id). Also the use of Hibernate template is now discouraged. Take a look at the Spring documentation for the preferred approach.

I guess everyone has an angle. Fine, what do you want? Just know that you cannot have this tiny ad:
