Java and JavaScript Support for Microsoft Visio

Many UML diagramming tools are not backward compatible which requires software developers to redraw their diagrams with each new version of the tool. On the other hand, Microsoft Visio is a diagramming tool that has almost always been backward compatible but unfortunately does not include support for Java or JavaScript. From this article you can download two files that add Java and JavaScript support to Visio which will enable you to draw UML diagrams based on Java and JavaScript that won't have to be redrawn in years to come.
