| EJB and JDBC The need to connect to databases from within EJB is clearly one of the more significant needs of the EJB specification. All J2EE-based components need to talk with a database, and J2EE provides support for this via JDBC. Vendors such as Oracle and a future J2EE specification will allow the use of SQLJ to provide database connectivity. However, the primary approach that I advocate and assume here is to use JDBC. J2EE-compliant environments provide access to the JDBC API and serve as a convenient means for configuring JDBC resources via the XML-based deployment descriptor and for connecting to JDBC resources via JNDI. |
