In this chapter, we continued the analysis of the application server configuration by looking at Java's enterprise services.

We first learned how to configure datasources, which can be used to add database connectivity to your applications. Installing a datasource in WildFly 8 requires two simple steps: installing the JDBC driver and adding the datasource into the server configuration.

We then looked at the enterprise JavaBeans subsystem, which allows you to configure and tune your EJB container. We looked at the basic EJB component configurations (SLSB, SFSB, and MDB) and then looked at the EJB timer service configuration that can be used to provide time-based services to your applications.

Next, we described the configuration of the message-oriented middleware, which allows you to loosely couple heterogeneous systems together while typically providing reliability, transactions, and various other features.

Then we moved on to the transaction subsystem configuration, which can be used...
