We have a J2EE application with Swing as a front end and we have EJB on the middle tier
As we have to render graphs in client side so Swing has been our primary choice so far
In past we have tried development with Struts ,JSF, and Ajax and we had lot of issues with Memory size , Session replication
Recently i have tried GWT and it looks great and we like it .
Based on our past experience we have still few questions about the framework and this will help us to decide
1)What would be the performance impact for application migrating to GWT?
2)Where GWT is storing in memory data in server side is it in Session or any other caching framework ?
3)Does GWT support clustered environment (Session replication all that kind of stuff) ?
4)Is there anyway we can port our existing Swing application to GWT(Instead of rewriting the whole UI layer)
Please share any if anybody is currently having any Session and Performance issues in vaadin
