Thank you very much Emmanuel for you fast response, this information is very useful to me.

Soon, when I had finish the prototype that I am writing now to check the integration with GWT libraries, I will share here in the forum the additions I did to the SweetHome3DApplet source files to embed the applet into a GWT application, and some fragments of code of the GWT application.

Also, when the new version of our appliation will be online I will send you a link to our application, so you could check how we use Sweet Home 3D inside our project.

Have a nice weekend,
Roberto
