Java Client-Side Components

Java client-side components are a feature of WebObjects that enables Java applets on the client browser to synchronize state with the associated component on the server side. Using this feature, applets can also cause the invocation of action methods in the server. This chapter describes the advantages and design of Java client-side components. It also explains how to integrate client-side components into a WebObjects application and how to make your own client-side components.
