System Requirements

A user needs to register to obtain a user ID before using this program. A web browser with JavaScript and cookie support is also required. To upload big files, JMaster's "JumpLoader" might be helpful. As a Java applet, JumpLoader requires the browser's support for Java.
As our main web browser used for testing/debugging, Mozilla Firefox is strongly recommended for users to explore WebArray/WebArrayDB. We also tested the program with Opera, Flock, Microsoft Internet Explorer (IE), and Google Chrome.
