Plumtree Software announced the release of a new add-on to its Enterprise Web Development Kit (EDK), for creating interactive portlets using Microsoft .NET Web Controls. Part of Microsoft’s .NET Framework, .NET Web Controls are visual drag-and-drop elements that developers can use to create Web applications. .NET Web Controls created by Microsoft and the .NET development community can now be used without any coding to create portlets within the Plumtree Enterprise Web Suite. The Plumtree EDK offers services, sample code and documentation for using Java and .NET development tools to build portlets and Web services. Plumtree supports JSR 168 and WSRP portlets, Apache’s Java Struts, Sophia, Java Server Faces, C#, Visual Basic.NET and Java Server Pages. The newly released add-on to the EDK allows .NET Controls to function as-is within the Enterprise Web as portlets. Using Plumtree’s Active Portlets technology for communications between portlets within an application, the Control-based portlet can refresh within the page without causing the rest of the page to refresh.
