guacamole: home folder location
posted on 2015-09-25 20:26:01

guacamole is a 'clientless rdp gateway' based on HTML5.

Sadly its pre-1.0 and has some hiccups.

One being the location of GUACAMOLE_HOME.

From its documentation:

GUACAMOLE_HOME

Guacamole reads files from its own configuration directory by default, resorting to the classpath only when this directory cannot be found. When locating this directory, Guacamole will try, in order:

The directory specified within the system property guacamole.home.

The directory specified within the environment variable GUACAMOLE_HOME.

The directory .guacamole, located within the home directory of the user running the servlet container.

For tomacat7 that should be /usr/share/tomcat7/.guacamole. If you place folder somewhere else, without specifying the GUACAMOLE_HOME environment variable properly, no configuration will be loaded.

I have not read that excerpt above properly, and had to track that fact down in the source, maybe this will help someone.

In the source it were to be found here in line 44:
