Thank you very much.

The sweethome3d and sweethome3djs projects were also compiled.
I searched a lot, but nowhere did I find information on what to install on tomcat on my own server.

Currently, the html file contains things like sweethome api / readHome / ..., furnitureCatalogURLs: ... lib / resources / DefaultFurnitureCatalog.json, and so on.

However, in the sweethome3djs project (which I had to rename from zip to war), there are only js files in the lib folder and there is even the default.sh3d file. There is no resources folder or /sweethome3d.css.

Nor did I find any information on whether I should use version 6.6.4 in the html file differently than before.
