Hi,
I just installed icy on ubuntu 12.04 and it runs nicely on my local machine.
my home is also mounted on a more powerful server with the same ubunut and java-version as my desktop machine
maid@joan:~/localsoft/icy$ java -version
java version "1.6.0_27"
OpenJDK Runtime Environment (IcedTea6 1.12.5) (6b27-1.12.5-0ubuntu0.12.04.1)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)
but when i start it in a shell with X-forwarding, I get the following error and no application window appears:
maid@sprtschk:~/localsoft/icy$ java -jar icy.jar

Any Ideas what could be the error?

Hi,
To launch icy from the command line it's better to use:
As it will apply the correct specific JVM parameters (as allocated memory) to launch icy.
About your error, it looks like the JVM does not see the X-forwarding and just assume you try to start Icy on a headless system (no screen device). Icy should support headless mode (you can then only launch batch plugin on a specified image) but it looks like there is a problem with it. Anyway i guess it is not supposed to work in headless, did you get other java application working with X-forwarding ?

Hi,
thanks for the reply.
If I try to launch icy with:
java -jar updater.jar or java -Djava.awt.headless=true -jar updater.jar
nothing happens - it returns to the command prompt more or less immediately with no output or opened windows.
Also, when I use the " -Djava.awt.headless=true" option, it has the same output as above.
I regularly use imageJ and MATLAB on this machine (the one with X-forwarding) without problems.
best regards,
Dominic

Hi,
Actually if you set manually java.awt.headless to true Icy will directly detect the headless mode and return immediately if you don't specify any command (plugin execution mainly).
I guess there is a bug in the substance library (the look and feel we use in Icy) so it does not detect correctly the graphical device and think we are headless where that is not the case as you do X-forwarding.
I will report that issue to the developers of the library so they can fix it. Hopefully we have our own dev branch of the lib so we can fix it on our side. I hope to deliver a fix for that in the next version :)
Thanks for the report !

I replied a bit quickly, after dig in the code the problem seems to be on the java side and more specifically with the Toolkit.getDefaultToolkit() method which actually returns the headless instance of the toolkit where it should not...
I guess the default sun.awt.X11.XToolkit should be loaded but that is not the case here.
Do you use a specific command for the X-forwading ? You may need to set some variables to inform java about the X-forwarding.
I even surprised it does work with ImageJ as the ToolKit problem should appears too (or ImageJ does not use Toolkit class but that would be surprising).
