Pro Apache Tomcat 5/5.5 (Experts Voice in Java)

In this chapter, you saw JDBC connectivity in the context of Tomcat. The most obvious interaction is the need of Web applications to connect to relational database sources.

I discussed Java’s support for accessing relational database management systems (RDBMSs) in the form of JDBC. I covered the JDBC version evolution, and I talked briefly about the different types of JDBC drivers that are available.

Next, you saw the recommended way of providing a JDBC data source to Web applications, which involved the configuration of JNDI resources in the Tomcat configuration file. In addition, Tomcat also provides a database connection pooling service through the Jakarta Commons DBCP project.
