Sweet Home 3D Online Manager

[pohlmannfrank]

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 to work without saving changes. Or is there a tutorial for this?
Best regards

However, there must be a connected user for everything to work

No, the default web application proposed with Sweet Home 3D JS is able to record the changes made in a file matching the [font=courier new]home[/font] parameter sent to [font=courier new]index.jsp[/font] (see also [font=courier new]readHome.jsp[/font]). For example:

Code: Select all

http://localhost:8080/SweetHome3DJS/index.jsp?home=MyHome

will edit the file [font=courier new]MyHome.sh3d[/font], creating it if it doesn't exist.
But if you don't want to keep all the SH3D files in the same folder and/or prevent the SH3D files of a user from being read by anyone, you'll have to program some authentication system, the reason why I reused the forum login page as a SSO (Single Sign-On) on sweethome3d.com. But you could also start without authentication and use a permanent cookie to name the folder matching a user on the server.

is the Online Manager also available for download?

No, because it depends on the forum authentication system and how sweethome3d.com database is organized. I could program also a less specific solution but I prefer to spend some time on Sweet Home 3D improvements now.

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 ... d0039d64b7 404 (Not Found)

die user Resources kann ich sehr wahrscheinlich einfach aus der index.jsp rausnehmen? das sh3d-File kann aber nicht geladen werden. irgendeine idee was ich falsch mache?

[pohlmannfrank]

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?

[Puybaret]

You'll get the first error as long as you didn't modify preferences, since [font=courier new]userPreferences.json[/font] file will be created at that moment.
For the second error, it's an HTTP 500 error so you should check logs on server side (there's probably a stack trace in [font=courier new]logs/catalina.out[/font] file).

Thanks, i get the following error:

What can i do?

[Puybaret]

Resource specification not allowed here for source level below 1.7

You probably run Tomcat with an old Java version. Use at least Java 1.7 or the JDK you used to build the project, since it required Java >= 11.

[pohlmannfrank]

now i have this configuration
Apache Tomcat/7.0.106 17+35-2724 Oracle Corporation Windows 10
but it doesn't work

[Puybaret]

Maybe it's an issue with Tomcat. I never tried with Tomcat 7. Can you try with Tomcat >= 9?

[Edit] Actually, you're not the first to encounter this issue, and I think the solution for Tomcat 7 is described here.

[pohlmannfrank]

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