    Factory pattern and CRUD operations

    Arbi Sookazian Master

      So one of the tables/entities is being updated in the table after I submit my use case for a particular employee/row.

      I have not coded any explicit calls to the DAO methods. The submit() method in my SFSB simply has a log4j output statement.

      So how is the update transaction actually happening? This app was reverse-engineering using JPA reverse engineering (via MyEclipse). So is this a feature of EJB3 (I saw in the server.log that the SFSB was being serialized at one point)? The only reference to ".merge" in my entire project were commented in the submit() method below. Only references to "update" are in the DAO classes.

      so what's the explanation here for the save/update?

      here's the entire SFSB:
