JavaServer Pages (JSP). A JavaServer Page is similar to a servlet and
allows for the creation of dynamic Web pages.
Java Database Connectivity (JDBC). JDBC allows Java applications to

access a database.
Extensible Markup Language (XML). XML provides a mechanism for
describing data using tags in a platform-independent manner.
Java Naming and Directory Interface (JNDI). JNDI allows Java applica-
tions to access naming services and directory services.
Java Transaction API (JTA). JTA allows Java applications to access a

transaction service.
Java Transaction Service (JTS). JTS defines the implementation of a
transaction manager that supports the JTA.
Java Messaging Service (JMS). JMS allows for Java applications to

access a message service.
Java IDL. The Java IDL allows Java applications to use CORBA
implementations.
JavaMail. JavaMail allows Java applications to access an email service.
RMI-IIOP. RMI-IIOP is for using Remote Method Invocation over the
Internet InterOrb Protocol.
Connectors. Connectors allow Java applications to access enterprise
information systems.
Java Web Services. Java Web Services allow Java applications to take
advantage of the emerging Web services technologies.

Similar to J2SE programs run in a JVM, J2EE applications run in a J2EE-
compliant application server. The application server implements the J2EE
specification, allowing developers to create applications that use any or all of
the J2EE technologies, but that still are platform independent. Some of the
more popular applications servers are IBM's WebSphere, BEA Systems'
WebLogic, and Macromedia's JRun.

Downloading the Java 2 SDK

As mentioned earlier, this topic focuses on the J2SE, the Java 2 Platform, Stan-
dard Edition. By the way, there is no Java 1. Before Java 2, the versions of Java
were referred to by the version of the Java Development Kit (JDK). The first
release of Java was JDK 1.0, which was released in 1995. The next release was
JDK 1.1 with enough changes and additions to JDK 1.0 to make the two
