JavaMail is a simple way to send email from your Java applications. All you need is the mail.jar (JavaMail) and jaf.jar (JavaBeans Activation Framework) files in your classpath (and access to a mail server). Javamail is especially useful because it is protocol independant. This tutorial is a basic introduction to JavaMail. The method below is all it takes to send email with JavaMail.

This lesson illustrates the use of the security-related tools ( keytool, jarsigner, and Policy Tool). It also shows use of the jar tool to place files in JAR (Java ARchive) files for subsequent signing by the jarsigner tool.
In this lesson you first execute steps to create an application, put it in a JAR file, sign the JAR file, and export the public key certificate corresponding to the private key used to sign the JAR file. For convenience, you pretend to be Susan Jones, and you supply information about her when you generate the keys.

Mandy's first article on firewalls helped you get to know your needs and put your security policies in place. In this, her second article on firewalls, Mandy focuses on the technologies available on the market today and some key decisions that need to be made throughout the selection process. The three main firewall technologies are: packet filter, proxy, and stateful inspection. Mandy reviews the pros and cons of each technology, as well as their advances, hybrids, features, and customization.

The Java platform provides a powerful framework for creating international applications. Support for the Unicode Standard is only the beginning. You need to understand how to isolate language-dependent resources such as 'prompt strings' for your program logic; how to package these resources in resource bundles; how to accommodate text that may not read from left to right, and how to rethink your application.

Creating a global application isn't particularly difficult, but it does require you to become familiar with the most common international problems and their solutions. The problems associated with creating an international application are basically the same from one computing environment and language to any other. Solutions are roughly equivalent as well, although their implementations obviously differ among the various computing environments and programming languages. This article gives an overview of internationalization topics and concepts in a Java programming environment, and covers the following features available in the Java Development Kit 1.1.

In this article, we get to know some of the reusable designs that can be used to improve the performance of a J2EE application. For the benefit of those who are not familiar with design patterns, a brief description is given at the beginning before delving into the details. For further details on design patterns, see the reference section at the end of this article.

Distributed computing is in demand. Developers and companies are embracing the technology quickly. Both complementary and competing software packages are being deployed monthly. At the forefront of this hype is the Common Object Request Broker Architecture (CORBA) specification. Whether there are new net-centric languages such as Sun's Java or component-object models such as Netscape's ONE, they all tie in with the Object Management Group's (OMG's) CORBA specification in one way or another

If you plan to build a scalable and highly available Website, you need to understand clustering. In this article, Abraham Kang introduces J2EE clustering, shows how to implement clusters, and examines how Bluestone Total-e-server, Sybase Enterprise Application Server, SilverStream Application Server, and WebLogic Application Server differ in their approaches. With this knowledge you will be able to design and implement effective and efficient J2EE applications.

In general terms, a component is one or more classes with an external API that satisfy some requirement. But how do you build components that are really practical--that handle configuration changes or third-party integration well? Palash Ghosh has some ideas about the concepts behind components.
