Join Ketkee Aryamane for an in-depth discussion in this video Define the session bean class for database operations, part of Java EE: Concurrency and Multithreading.
- [Instructor] Now let's do the next step.…We have to create a TransactionBean…which is going to do those DB operations…against the respective tables.…The bank account transaction…and the bank account transaction log, right?…So let's go back to the IDE and under the…source packages, I'll add a package…and say com.app.ejbBeans.…So I'm going to create a stateless session Bean.…If you remember in our earlier videos…we talked about this concept.…It is basically a kind of enterprise Java Bean…which allows you to do independent operations…based on your request processing needs.…
So I'm just going to say finish.…And here I'll create a session Bean.…Let's name it TransactionBean.…Okay, and you do see it is already annotated…with the stateless annotation.…Let's also give this Bean a name.…So I'm going to say, bx Bean.…Now here, we have to define a couple of methods.…One, to save the bank account transaction information,…And the other, to save the bank account…transaction log information.…
So let's go ahead and start doing that.…
