Did you deploy your own furnitureCatalog.zip and texturecatalog.zip files or the ones available on sweethome3d.com? Did you set the furnitureResourcesURLBase and texturesResourcesURLBase attributes and deployed the furniture icons and models on your server? Or maybe you want to show your own models/textures?
You ask quick support but don't tell us anything about your project. It would be nice to give some details about what you want to achieve...
By the way, pay attention that applets are a dying technology: not available under iOS and Android, not available under Chrome and Edge browsers, difficult to use under Safari. Among the main browsers, only IE and Firefox still support them with the only requirement that the user must install a JRE and accept applet certificate at launch. For how long???
