They reside on the server and get downloaded to the user's desktop on demand. Once downloaded, the Java applet connects directly to the mainframe, without going back through the server. Users are presented with a standard terminal screen and interact with the mainframe application just as they would with traditional emulation software. Rejuvenation products convert legacy screens into intuitive web-style interfaces. Rejuvenation technology Rejuvenation products extend mainframe applications to new users by giving legacy screens a fresh, web-style makeover.
Some products carry out the conversion process automatically.
Others include integrated customization tools for developers who need to create highly specialized interfaces. Rejuvenation products do not change the workflow or functionality of the mainframe application. For this reason, they are best-suited for occasional users or tightly integrated partners who understand the basic functionality of the underlying application, but require an updated interface in order to work more productively. One drawback of the technologies described so far is that they are tightly tied to the limitations of the mainframe application. This makes them unsuitable for users who are unfamiliar with legacy navigation, i.e., loosely integrated business partners and consumers.
