As RIA (Rich Internet Application) technologieshave been widely used, the compatibility problem has arisen:they are hardly compatible with each other. To solve theproblem, we have proposed and implemented an automatic RIAtransformation system named Web-IR, which uses anXML-based intermediate representation with a Java-basedframework. As concrete examples, Web-IR currently supportsAjax, Flex, JavaFX, and OpenLaszlo as its input/output. Ourevaluations show that Web-IR can transform existing realapplications into other RIA technologies keeping almost thesame appearances. Finally, we conclude that Web-IR can solvethe problem sufficiently
