We have now completed the EJB. Now we have a complete vision of the beans working in the background and the business components in Java EE.
EJBs are a recent technology but are the best components to solve issues related to transaction development, competition, and security. We've seen that with a few lines of code, we are able to provide components that are ready to be immediately put into production environments. With EJBs or developers, you just have to focus on the business logic once you choose the component that best suits your situation.
In this chapter, we anticipated the schedulers and timeouts, thanks to the EJB. More complex schedulers will be seen in the next chapter in a deeper mode. Java EE grows increasingly, adapting to the necessary requirements of customers.
