Today at work I built a page which does the following:
An iframe is used to embed an HTML page which consists of nothing but a <script> tag whose source is a Java Struts action. That action then forwards to a JSP which uses Java to build Javascript to build HTML to be outputted to the screen. The resultant HTML is a form which calls yet another Java action for searching. This is possibly the most worthless and most overcomplicated project I’ve ever done.
