Build Cooperative Domino Data Portlets with WebSphere Portlet Factory [Part 1]

摘要

Inter-portlet communication can be a tricky (and often puzzling) endeavor. Although "cooperative" portlets (portlets that can communicate with each other) increase the flexibility of your applications and encourage component-based design, facilitating this kind of communication often involves numerous configuration points (such as WSDLs, the WebSphere Portal admin interface, and Java code), and thinking of applications as collections of smaller, function-specific portlets can be difficult for Domino developers because we're used to the single, standalone interface in most Notes applications. The good news is WebSphere Portlet Factory (WPF) greatly simplifies the process of creating cooperative portlets, with the introduction of several builders to help shield you from the underlying complexities of inter-portlet communication. Builders in WPF are like wizards that essentially automate the process of writing code, and there are builders to do everything from adding buttons to your pages to calling web services.
