I installed it by downloading the rpm and installing that. IBM said on
my older FF the app/plugin is called JNLP and I should change the
setting for that to 'always ask' and then when it asks use javaws - I
did that but it still fails.

Again, please enter 'about:plugins' in the address bar of your browser
to make sure, that the right java version is activated.

But normally javaws is a different topic. As far as i remember, there
should be an option to let firefox ask, which javaws should be executed.
As i understand, you have different version installed.

And at last, please check the security options with jcontrol. Newer java
version are more restricted about security settings.

best regards
Ulf

When this was working before the firmware update the RC software
invoked IcedTea. As one of the attempted fixes IBM suggested using
javaws instead. Intially I did not have javaws but I did have
javaws.itweb. I tried that and it failed in the same way.

Then they asked me to run this:

alternatives --config java

There are 2 programs which provide 'java'.

  Selection    Command
-----------------------------------------------
*+ 1           /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java
   2           /usr/java/jre1.8.0_144/bin/jav


And switch to the second one. When I did that it still failed with
IcedTea, but then there was a javaws. I ran that and it did completely
different things and finally failed with "Login error". They they had
me go into ControlPanel and put the IP address of the IMM in the
excpetion site list. I did that and then I get: KVM Java: Duplicate
exists. Then they gave up and said they don't know.

I don't seem to have jcontrol
