Hi All,
I can not get the guacamole client to work on my system I followed the
instructions in the manual for native install and a couple of other
walk-through,even gave the docker version a shot. guacd compiles and
runs fine (native) but the client will not start version 1.5.5.
My system specifics :
Debian 12/bookworm 6.1.0-23-amd64
Tomcat 10.1.6 Debian
JVM Version 17.0.11+9-Debian-1deb12u1
or
JVM Version 11.0.18+9-LTS-195
The Manual DOES NOT list, anywhere that I can find, required or
preferred/minimum java/JVM versions those two above are to ones I have
tried (I have). I can get others if I knew what I needed.
I am assuming by the error some class has been removed or renamed in
java , I get this same error with my compiled version of the client or
the downloaded war file from Apache. I am not much of a Maven or java
person, so no clue how to go about debugging this.
here is the error from the tomcat logs :
