Hi Mark, GWT (client side) is limited in that it executes in javascript. Javascript does not support reflection, and it is reflection that makes the bean specification, Tomcat, application servers etc etc work. It is also what makes "binding" domain classes to UI widgets work in Swing, SWT etc. In a web application running in a browser this is not possible (or rather not viably implementable in javacript AFAIK).
It is possible to buck this using e.g. Java applets, Adobe Flex, or Active X controls, bit all these require installation of native browser plug-ins. This problem is acutely felt in the Java world because e.g. Hibernate managed persistent entity classes use reflection and proxies extensively, so they are not translatable to javascript by the GWT compiler, and it is difficult to see at the moment how they could be, although many people would wish it so. Your point is well made, but given that a solution must perforce revolve around a single OS/language/browser etc, or accepted standards, who should establish those standards: Google. MS, Adobe, IBM, Oracle? Maybe W3C. My view is that DHTML is about as close as you get to a universal standard and GWT makes a pretty good fist of implementing it, deficiencies notwithstanding. regards gregor On Oct 5, 7:13 pm, mwaschkowski <[EMAIL PROTECTED]> wrote: > So the gwt framework would, using established stanards (ie. > javabeans), allow for improved tool support. > > Any plans? > > On Oct 3, 3:51 pm, Alex D <[EMAIL PROTECTED]> wrote: > > > Why would you need this kind of code in GWT? > > > On Oct 3, 3:50 pm, mwaschkowski <[EMAIL PROTECTED]> wrote: > > > > Hi All, > > > > I've been using a 3rd party wysiwyg tool to create my gwt interface, > > > and one thing I've run into is that gwt does not support java bean > > > type customization.
