A Java Front-End To CGI/Perl
Gunther Birznieks & Selena Sol
Java applets can create interfaces that go beyond the capability of HTML form tags, Javascript and VBScript. However, Java applets are limited in their capability of doing practical things such as connecting to databases, sending email, etc. The JavaCGIBridge project leverages the strengths of using Perl to connect to databases and perform application logic while using Java's superior GUI building facilities to provide a more user-friendly front-end to CGI/Perl scripts.

Problems with CGI/Perl alone

HTML forms have a minimal interface Hard to maintain state between forms

Redundant data frequently needs to be re-retrieved between HTML forms


Problems with Java alone

Bloated Applet Problem Java is hard! Security "Sandbox" restricts what applets can do Problems with Java Applets
