jstm4gwt - Java Shared Transacted Memory for GWTjstm4gwt helps with the developement of distributed GWT-Ajax applications. This library handles the data manipulation and synchronization with the server.
jstm4gwt automatically sends modified data to the server.
jstm4gwt automatically broadcasts changes to other clients.
jstm4gwt saves the user from implementing RPC services for each remote data operation.
jstm4gwt detects conflicts with changes made by other clients on the same data.
jstm4gwt allows data modifications to be done within transactions, and cleanly rollbacked if the transaction aborts.
jstm4gwt is simpler to use than SOA design since you don't have to define services but you just have to work on your functional data and implement listeners on client (refreshing UI ) and on the server (persistence, mailing, ...).
jstm4gwt can be very efficient, e.g. for gwt multi users games.
jstm4gwt allows you to setup a powerfull distributed gwt application in few minutes.

To get started, download one of our samples. E.g. the Images demo. It contains a Jetty server with the demo code. Just unzip it and launch the server using start.cmd, then launch two browsers by clicking twice the Browse.url shortcut.
Have a look at the web site for the parent project JSTM, and to the JSTM blog.
