Examples of org.directwebremoting.proxy.dwr.Util

org.directwebremoting.proxy.dwr.Util
Util is a server-side proxy that allows Java programmers to call client side Javascript from Java.
Each Util object is associated with a list of ScriptSessions and the proxy code is creates will be dynamically forwarded to all those browsers.
Currently this class contains only the write-only DOM manipulation functions from Util. It is possible that we could add the read methods, however the complexity in the callback and the fact that you are probably not going to need it means that we'll leave it for another day. Specifically, getValue, getValues and getText have been left out as being read functions and useLoadingMessage etc have been left out as not being DOM related. @author Joe Walker [joe at getahead dot ltd dot uk] @author Jorge Martin Cuervo [darthkorr at gmail dot com] @deprecated Use org.directwebremoting.ui.dwr.Util @see org.directwebremoting.ui.dwr.Util
