Summary

In this chapter, we discussed the different options that Apache Geronimo provides to connect to relational database systems. We saw how to configure database pools of various scopes using different tools, such as the Administration Console, the command-line deployer, and GShell. We also took a peek into how we can import a database pool configuration from another application server, and how an enterprise application developer can configure an enterprise application to use the database pooling functionality provided by Apache Geronimo, for efficient database access. This covers most of the common things a Java EE developer using Apache Geronimo will need to know about database connectivity in order to enable him or her to use it to its fullest potential. In the next chapter, we will discuss the support provided by Geronimo for the Java Message Service (JMS). You will learn to configure the embedded JMS server, create JMS resources, and use JMS resources in Java EE applications.
