To me the serverBaseUrl looks correct:
Wed Apr 13 17:46:10 CEST 2022# serverBaseUrl: https://craftbutlerdraw.de:443/cbd/

The sh3d file is not created. The browser console always shows an attempt to carry out an update, but this runs with errors.

After it runs locally for me, I rented a server from a hoster with a Tomcat 9 and now I get the following error message there.

13-Apr-2022 16:02:46.617 SEVERE [ajp-nio-0.0.0.0-41118-exec-5] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [jsp] in context with path ...

it is now running on Tomcat 9.
Thank you for your patience

Apache Tomcat/7.0.106 17+35-2724 Oracle Corporation Windows 10

last sentence above:
I can probably just take the user resources out of the index.jsp? but the sh3d file cannot be loaded. any idea what i'm doing wrong?

when I try this I get the following errors in the browser console and the sh3d file does not load:
sweethome3d.min.js:20 GET http://localhost:8081/SweetHome3DJS-7.0/userResources/userPreferences.json?requestId=c0bb3516-de3d-487f-89fc-e0d0039d64b7 404 (Not Found)

First of all: Really great software! Thanks for that!
I have now installed Sweet Home 3D JS on a lolalem Tomcat. However, there must be a connected user for everything to work. My question is: is the Online Manager also available for download? I'm just hanging here a little because it's not possible ...

I found the mistake. I had jsweet installed with a more recent version of node. After installing node in version 14.6, I have now redeployed jsweet. The war file has now been deployed.
