Introduction The advent of Java has traumatized the performance of an already slow Internet. Bringing up a new Web page now requires fetching graphics, applets, JavaScript, etc. You can`t change the world, but there are things you as a content-designer can do to make your Web pages load faster. This, in turn, translates into a higher likelihood that the user will continue browsing your site, rather than just giving up. In this article I will discuss five techniques to improve Java loading performance: 1. Use of the 'archive' tag in Netscape Navigator 3.0 2. Implementation of a progress monitor 3. Use of HTTP Keep Alives 4. Dynamic loading of classes 5. Class compression by symbol reduction Background and Performance Measurements One of the largest components of fetching a file via HTTP can be the TCP connection setup and httpd server accept() portion of the connection.

ObjectStore PSE Pro

Object Design's ObjectStore PSE Pro for Java is a native Java-persistent object database (PSE stands for Persistent Storaget Engine). It allows running Java objects to save and restore state. The differences between the Pro' release and the general release involve the ability to simultaneously access databases and to recover databases. ObjectStore PSE Pro is aimed mainly at the Java application programmer. Its object-oriented database provides an alternative option to JDBC, which is likely its main competitor. ObjectStore PSE Pro will work with any Java Virtual Machine - it's 100... (more)

Remote Debugging with Symantec Cafe

Java applets can be used to provide better dynamic interaction with the user on Web pages than simple CGI scripts and html forms. However, like any programming language, the code does not spring forth perfect, but rather is designed, implemented, and then debugged. Debugging code that lives on a Web page can be difficult. The old standby of trace printfs (or System.out.println in Java terminology) is always available, but tedious at best. The JDK, available from JavaSoft, contains a debugger, jdb, but it really serves best as a sample implementation rather than as a development ... (more)

Macro Component Use

When designing a Java applet or application, you often may wish to place a similar set of components in several different places. Perhaps you would like to have a labeled text entry field, or a more complicated structure like a list of IP addresses and subnet masks, with entry fields for each. You could do these by creating a Panel, placing them there, having a method in your class to create this, and returning the Panel. There is an easier way. A 'macro' component [treating multiple components as a single object] is a simple step between writing a custom component which handles a... (more)
