Java servlets provide a new way to develop server-side solutions. They provide the features of traditional CGI scripts with the additional benefits of efficiency and portability. Currently, major corporations are making the migration from CGI scripts to Java servlets. As a result, the demand for applet and servlet communication is on the rise. In the February 1998 issue of JDJ (Vol. 3, Issue 2), I presented a three-tier database application that used Java servlets. In this article you will learn how to build a three-tier database application that allows a Java applet to perform two-way communication with a Java servlet. I'll focus on the concepts and techniques of applets communicating with servlets, building on the application presented in the previous article. Don't worry if you missed that article; a review follows. Reviewing Our Student Tracker Application The pr... (more)

Migrating CGI Scripts to Java Servlets

Introduction The rapid acceptance of Java for client and server applications has created an immediate need to move existing CGI scripts to Java servlets. Java servlets are server-side components that can extend the functionality of a Java-enabled web server. Currently, there are a number of enterprise web applications that provide server-side functionality with CGI scripts. Java servlets provide a number of enhancements to the current CGI architecture. In this article, you will learn what servlets are, how you can integrate them into your web application and what the benefits of u... (more)

Developing 3-Tier Database Applications with Java Servlets

The drive to create a successful Web site has resulted in Web applications that are interactive and informative. A wealth of information is stored in corporate databases and there is a rush to publish this information on the Web. Corporations' traditional client/server applications are being edged out by Web-based applications. This occurrence is possible thanks to the universal client, the Web browser. This article is the second in a three-part series on Java servlets. Last month (JDJ, Vol. 3, Iss. 1), I gave you an overview of the Java servlet technology and how to migrate you... (more)
