Low level servlet and JavaScript libraries
The low level servlet and JavaScript library provide the basic infrastructure for building Web applications that display a graph. In Rogue Wave JViews Diagrammer, the contents of the graph come from a diagram component.
To make it easier to build Web applications that display a diagram component, Rogue Wave JViews Diagrammer extends the basic JViews servlet and JavaScript support, providing classes that let you implement the server side of your Web applications with little or no coding.
If you want full details of lower-level servlet and JavaScript support, see Developing basic JViews JavaScript Web applications. Note in particular that the architecture for JViews Diagrammer is equivalent to that described in JViews Web technology architecture, but more specifically:
*The JViews Application is a JViews Diagrammer application, containing an IlvDiagrammer instance.
*The JViews Servlet is a JViews Diagrammer servlet, based on a JViews Diagrammer server-side class.
