I am getting ready to put together and design a Spring MVC based front end for a client that plans to use JQuery for some of the more complex GUI and Async processing.

Im curious if anyone has some advice on how well ExtJS can integrate within a Spring MVC site. From what I can tell The ExtJS components could completely replace the JSP pages used by the Spring Framework but I am more interested in knowing if the ExtJS libraries can be effectively used to Augment a Spring JSP and its associated taglibs.

I would welcome anyones thoughts and experiences who have worked on integrating ExtJS into this or a similar framework
