When I think about the strengths of Java, I always think of two things: its networking classes, and its ability to instantiate a class from a string. These features get their support through part of the class loader mechanism, which enables a web browser to load your applet's classes. In a large development project, it can be really useful to be able to specify in a .ini file, which support the services you would like to have running. To demonstrate this,...

the Java story has largely been a client-side story. That's about to change. Now web servers can be extended through Java power just like web browser clients. In the context of client-server software solutions--including the serving and browsing of Internet web pages--Java applets have enabled client browsers to extend their behavior by downloading compiled code from network servers. Applets have changed the nature and meaning of...

One area of Java where you can get into trouble is trying to balance memory management with performance. Take, for example, double buffering. Usually when you are drawing on a buffer, you aren't exactly sure how large a buffer you will need. In this example, we are using a 600-pixels-by-600-pixels applet window. The image we want to buffer is a grid of squares, which is 2000-pixels-by-2000 pixels. Here are some rough numbers on how much memory the buffer...

Click here for some sample code that shows you how to do it. Using this code to override Component.update() handles double-buffering in a way that usually lets programmers reuse their existing paint methods without modification. (You can't do this, however, where the applet or component draws directly to the screen without calling paint .) This can even be put in a subclass of Canvas or Applet (called perhaps...

Ever since the advent of the internet, Java has been the target for many developers. Many C++ developers migrated to Java within a short period of time. Many high quality multithreaded animations, games, distributed applications are being developed and implemented successfully. Moreover the Java language is completely Platform Independent. Java Programs called Applets are verified for security in user's machine before downloading, thus ruling out the possibility...

Based on the Java SM Developer Connection SM presentation, Tips and Tricks for Java Developers given at JavaOne 1998, this article offers a variety of performance tuning and firewall tunneling techniques used by the Java Developer Connection (JDC) engineering team. These techniques are illustrated by source code that you can download . Performance--Applet Download Speed An important factor affecting any Applet's download performance is the...

NakovDocumentSigner is an example of putting the pieces of the puzzle together. NakovDocumentSigner is a freeware, open-source framework for digitally signing documents in Java-based Web applications developed at Sofia University "St. Kliment Ohridski" by Prof. Svetlin Nakov and his team. The framework consists of the following components: A signed Java applet that is used to digitally sign files before uploading them to the server. A...

Java is a powerful, object-oriented language that supports much functionality, including client/server communication through socket programming, windows-based programming, console programming, database connectivity, image, and sound programming. Java is mainly designed for Internet programming and to create small applications that can be embedded inside an HTML page, known as Applets . Before coming to the actual coding of the program, some important terms...

What does the creator of one of the hottest Java sites in the world think about Java's future? Just ask, and Gamelan Founder Alex Chaffee is glad to give anyone who is listening his vision of Java's potential. "Just as HTML was so easy to use that anyone with a small level of computer literacy could publish their own Web page, Java is easy enough that anyone with a small level of programming skill can do cool, distributed applets and applications. This will...
