Thanks.

@tgadmin I was a bit skeptical whether this will work because the plugin is ~4 years old but surprisingly it works.

• Install guacamole

• Upload branding.jar to /app/data/extensions

  

• Restart guacamole

I did some random color changes and got something...

One thing that tripped me was that when re-creating the jar file after making changes, all the files must be at top level and not inside a directory.

@girish I've modified mine but for some reason it doesn't work, it shows the default page. If i use the the original branding jar file it updates and shows the modified login page as shown in your first image. but i doesn't work with my modified jar file. I'll send the my jar file to support@cloudron.io and would appreciate if you can try it on your system and see if it works. thanks.

@tgadmin I guess you are trying to change the image?

If you see in, css/login-override.css:

        background-image: url('app/ext/tempnamespace/images/logo-placeholder.png');

So, the image has to be inside images subdirectory. In the jar you sent me, the images subdirectory is empty and there is an image in the top level.

I can send you the jar that i had.

Hi Guys
I am able to Edit the JAR File with 7Zip or WINRAR but after moving the editet JAR File to extensions it does not work. The original one works... can anyone help?I think there is a problem with editing with 7zip and WINRAR???

@playfun Been a while since I did this, but iirc, I just used the gnome (linux) archive manager. I extracted it and then made changes and compressed it.

Are you sure your jar archive has the changes you made?
