So you're asking how to set up some sort of remote desktop access? 

Wasn't there just a huge thread on this with a subject something like
"allowing work from home"?

[gentoo-user] Switching current java-vm for a single application

2016-01-31 Thread Leonardo Guilherme 
Hello.

I'm using OpenJDK JVM regularly on my machine instead of Oracle's one,
primarily because of the infinality patches and because I prefer open
source software.

There are some applications, though, that do not play ball with it (namely,
SenchaCmd) and I have to keep switching back and forth between installed
java-vms just to run it.

I know nothing about Java or its environment, is there a way to specify the
java-vm just for this application instead of doing "eselect java-vm set
user 1; sencha *stuff*; eselect java-vm set user 3" everytime?

Is there a set of environment variables that can do this? Shall I wrap the
command in a shell script? Ideas?

That was my thread too but this is an unrelated use case.  There's a
desktop Java app I want to run in the cloud and still control the GUI and
I'm trying to figure out the best way to do that.  Maybe it's "install
Gentoo and VNC" but maybe there is a better solution.

Citrix has the citrix receiver (look for icaclient on the tree) which will run 
a remote desktop on your Gentoo.

Or only the application window when using xenapp.

I'm not sure if it will work with a Linux desktop. Always seen it used with MS 
Windows.

I've been researching this and I think my options are a) get a VPS and
install Gentoo, this Java GUI app, and VNC, or b) set the app up with a
Desktop as a Service (DaaS) provider.  Option B should require a bare
minimum of maintenance so it's really appealing.  Here are the providers
I've found that can provide a Linux desktop:

https://www.omnis-systems.com/virtual-bridges-vdi/virtual-bridges-general-information

http://www.vdiworks.com/

https://www.vmware.com/products/daas-vspp/features

These don't specify Linux which makes me think they can only do Windows
desktops:

https://aws.amazon.com/workspaces/

https://v2cloud.com/virtual-desktop/

https://www.citrix.com/solutions/desktop-virtualization/overview.html

I suppose a Windows desktop would work since this is a Java app but I'd
prefer Linux.

Citrix also has a product called XenApp which is interesting because it is
supposed to provide only the app as a service instead of the whole desktop:

https://www.citrix.com/products/xenapp/overview.html

Many (all?) of these don't have a Linux client but some have an HTML5
browser plugin client.  I will try some of these and report back.

Did you try a different mirror? I think there might be an issue with 
specific host.
If so, contact its maintainer by email diplayed by rsync or file a bug to 
Gentoo infra...

What exactly do you mean by "run remotely"? Ssh to run on a different
host, container/vm to run locally are all viable options but I don't
quite understand what you're asking.

The problem was apparently fixed after I synced the next day.

Heck, since java is already running on the jVM I would even consider it
safe enough to just run as a different user or just in a chroot. 

In any case, none of this is gentoo specific.

Sorry, I should have been more specific.  I want to run a desktop Java
8 app remotely.  After more consideration I don't want to run it
locally because I want it to run all the time.  I have 2 ideas for
this:

1. set up a Gentoo install in a cloud VM, install the desktop app,
install VNC or similar
2. leverage a Platform as a service (PaaS) somehow

#1 should work but I'd rather not set up and maintain an OS instance
just for this.  Would VNC be the best way to get remote access to the
desktop app's GUI?  I don't need extremely high performance but
security and ease of setup/maintenance are important.

#2 is very appealing because it means I wouldn't have to set up and
maintain an OS, but I don't have any experience with PaaS and maybe it
isn't the right tool for this.  Does there exist a PaaS that provides
a Java environment for me to install a desktop Java app and then give
me remote control of its GUI?
