Charles, I used that exact example and it works for me. I'm not sure if you've confirmed that the extension specifies a compatible version of guacamole, and that it matches your version... I increased the logging level on mine following these instructions: https://guacamole.incubator.apache.org/doc/gug/configuring-guacamole.html#webapp-logging (logback file goes in your guacamole home). If that fails to increase logging then there's a "home" problem. That overall made it easier to debug within the web app, though not as easy as the eclipse tomcat plugin! -Ryan

Here's the scoop: Using this post - https://sourceforge.net/p/guacamole/discussion/1110834/thread/48fcbd3e/#bd49/2661, I'm able to confirm a lot of things. * I've looked into my /etc/passwd file and confirmed that my tomcat home is /usr/share/tomcat/.guacamole/. * Inside this directory I have my guacamole.properties file and the extensions folder. * I didn't have my GUACAMOLE_HOME environement variable set so I've done this now using an .sh script. Confirmed on reboot that my environment variable is set properly. * Inside this /usr/share/tomcat/.guacamole/extensions folder I have the guacamole-auth-jdbc-mysql-0.9.9.jar file. At the bottom of that forum post I'm following there is an example extension .jar file. I've used this to see if I can make changes to my login screen so I've copied this .jar file into my extensions folder so it sits beside the guacamole-auth-jdbc-mysql-0.9.9.jar file. I'm assuming both files can reside in the same folder without issue. * I then restarted tomcat and guacd services. Cleared my history on both my Chrome and Firefox browsers and loaded up my Guacamole site. Nothing has changed. * I then restarted my Guacamole server. Again no changes on my login page. I'm at a loss here as to why this isn't working? I did make sure that the .jar file of this customize extension has the guac-manifest.json in the root of the directory (and not in a subdirectory). I have no idea what log files to look into to confirm if my extension is even seen. But I'm assuming it's not recognized. Where should I look to confirm this? Any other ideas on what I need to do? Thank you.

I've searched my guacamole server for a guacamole.properties location. I found two: /etc/guacamole/guacamole.properties /usr/share/tomcat/.guacamole/guacamole.properties It would appear that one is a pointer to the other so basically I have found my guacamole.properties file. Looking within my guacamole.properties file I do not find an entry for GUACAMOLE_HOME. Should this environment variable be there? * Will defining a Guacamole_home environment variable then tell guacamole where to find my new extension .jar file? * And my Guacamole does work as of now in that I can login and use Guacamole. So how does my Guacamole currently work if it doesn't know where the Guacamole home is? Charles, I think all you need to do is create the extensions directory inside the /etc/guacamole and/or /usr/share/tomcat/.guacamole directory, then drop your JAR file in there and restart Tomcat or redeploy the web app. -Nick
