In this chapter we have shown deeply how to write the business logic for our beans and how the synchronous EJB works in WildFly 10. Now we can write an EJB, share it to the other enterprise components or call them through remote clients. We have shown how the EJBs work together with the transactions, that they are the main goal when you use a Java Enterprise compliant application server but we have not shown deeply the transactions. This will be the goal of the next chapter.
