The path used to retrieve "logo.png" should be:
.../app/ext/ndaw-crdp/images/logo.png
Not:
.../app/ext/ndaw-crdp/resources/images/logo.png

Some introduction: When I started this project Guacamole 1.4.0 was still the latest
version so I'm still using that to develop my extension. Once I have it working properly
I want to test it with Guacamole 1.5.1. Also, the company I work for is branding
Guacamole as "Clientless RDP" or CRDP so you'll see that name at several places.
I have the following files in place:
- guacamole-1.4.0.war file saved as /var/lib/tomcat9/webapps/clientlessrdp.war
- auth-jdbc extension saved as
/etc/guacamole/extensions/guacamole-auth-jdbc-mysql-ndaw-1.4.0.jar
- my branding extension saved as /etc/guacamole/extensions/ndaw-crdp-1.4.0.jar
When I start Tomcat the logs show:

So that seems fine. There are no other errors being logged. The missing logo is
only shown in the access logs:

I based my pom.xml in the pom.xml of the TOTP extension. I only changed the artifactId, name and
url and in the configurations for the angular-maven-plugin and minify-maven-plugin, I replaced
"totp" with "ndaw-crdp".

I’m working on a Guacamole branding extension and when I create a jar file by
zipping the directory, I can load the extension and images load just fine. The
strange thing is that when I package the files with Maven, the extension still
loads perfectly and while for instance the custom font is still working, the
paths to images that worked before no longer work. Tomcat returns a 404 error
when trying to open the image. When I open the jar file from Maven in 7-zip,
everything seems the same. I can see the images are there. It almost seems like
the path is blocked in Tomcat somewhere, but I can’t find where. Do you have
any pointers on where to look? If you need more information, please let me know.
You'll need to provide some more detail - maybe some logs from Tomcat,
and a rough idea of the configuration - what folder you're putting the
WAR file in, where you're putting the JARs, etc., so that we can
better help identify the problem.
A listing of the contents of each .jar and the contents of their
guac-manifest.json files would also be helpful.
