Make sure this actually *is* your jar's structure, not the structure of a
subdirectory within the .jar. You can list the contents of the .jar with:
unzip -l branding.jar
jar cf branding.jar branding #zip -r not working for me

Neither will this. You are creating a .jar containing a subdirectory called
"branding". The .jar should contain guac-manifest.json at the root, not
within a subdirectory, and all files referenced within guac-manifest.json
should be referenced relative to the root, not relative to a subdirectory.
If things aren't working, I recommend checking your results rather than
blindly making changes. Here is what "jar cf branding.jar branding" would
do:
[mjumper@dev-mjumper ~]$ mkdir branding
[mjumper@dev-mjumper ~]$ touch branding/foo
[mjumper@dev-mjumper ~]$ touch branding/bar
[mjumper@dev-mjumper ~]$ jar cf branding.jar branding
[mjumper@dev-mjumper ~]$ unzip -l branding.jar

Note how the files in question are still in a subdirectory, not the root.
You do not want this. The guac-manifest.json absolutely must be at the
root, and all paths within guac-manifest.json must be relative to the root.
mv branding.jar /usr/share/tomcat/.guacamole/extensions/

Why are you putting the "css" directory in GUACAMOLE_HOME/extensions/? It
should be part of your extension, as declared in your guac-manifest.json.
Guacamole loads extensions from the extensions directory, not arbitrary
directories containing CSS.

You do not need to restart guacd. Only tomcat.

Your files are all in a directory 'branding' - they shouldn't be.
When you create the .jar file, do it from inside the directory.
