Unable to get GaalVM to work on latest version of OS/X?

I have tried loading the latest versions of GraalVm from the site onto OS/X from : graalvm-ce-java11-darwin-amd64-20.2.0.tar.gz
I tar this bundle, following the instructions and sudo mv the directory to /Libaray/Java/JavaVirtualMachines and setup the .bash_profile per the instructions. If I run the java_home -V command I see the VM there.
When I try to execute any of the command line utilizes from the VM (java, javac, jar, etc.) I get a fault by OS/X saying the application is from an untrusted developer. I then I have to to control panel/security and settings/general and manually select each an every binary and each and every native library one at a time and tell OS/X to add them as an exception to allow them to be run.
Am I missing something or is this expected behavior? Is there a better way to install the graalVM on OS/X?

This is an old issue but maybe it helps:

I wonder why this has not been fixed yet.

student getting an exception from Play initialization

I created a Play app for students to use in an assignment for my user interface course. They don't need to modify it, just access it via AJAX. I used "activator dist" to package it up in a JAR file; they download it to their computers, unzip it, and run it locally.
It has worked well for everyone except one student. I'm at my wit's end for debugging and am appealing to the community for ideas.
The exception is:
Exception in thread "main" java.lang.NoSuchMethodError: ch.qos.logback.classic.LoggerContext.getFrameworkPackages()Ljava/util/List;

Things we've checked:
He's running Java 1.8.0_45. It was compiled with Java 1.8.0_66. He has reinstalled Java (which I'm assuming is 1.8.0_66 or greater). No change.
The md5 checksum of the download jar file matches the original.
lib/ch.qos.logback.logback-classic-1.1.3.jar exists and has the same size on his machine as on mine.
We've installed scala/Play/Activator on his machine, copied over the sources and tried compiling from scratch on his machine. Same error.
I've looked in the script prepared by "activator dist". I believe it's calling the same version of java as what we see from the command line. That is, I don't think we're being confused by two copies of the java runtime.
This is on a MacBook Pro (pre-Retina) with El Capitan.
Ideas?

clj-ssh / JSch unable to load library 'c' on Windows

I've added clj-ssh as a dependency to a Leiningen project, and I can (use 'clj-ssh.ssh) but calling (ssh-agent {}) gives the error
UnsatisfiedLinkError Unable to load library 'c': The specified module cannot be found.
at com.sun.jna.NativeLibrary.loadNativeLibrary
...
at org.jcraft.jsch.agentproxy.usocket.JNAUSocketFactory$CLibrary.(clinit)
...
Anyone know why this is? I'm thinking it could be to do with Windows not coming with a C standard library, in which case could installing e.g. cygwin help?

Try installing cygwin and add something like:
-Djava.library.path=...path to lib dir ...
if it doesn't find the library on it's own.

I'm the author of jsch-agent-proxy, which has been used in clj-ssh.
I think it will not work for cygwin's ssh-agent, because JNA does not provide
the native library for it. How about trying Putty's Pageant? If you need to use cygwin's ssh-agent and "nc" command exits on your cygwin environment, how about using NCUSocketFactory? I'm not so familiar with clj-ssh, but it will be possible to use NCUSocketFactroy instead of JNAUSocketFactory, according to agent.clj.
UPDATE:
I have confirmed that I can successfully run clj-ssh with
ssh-agent on my Cygwin environment by applying the following commit,
GitHub clj-ssh commit:f1109e2c0dfa25c9db563b2f64d2b7dcb4653adf

Ok, after some digging in the source it seems that clj-ssh attempts to use the system ssh-agent by default (which seems like strange behaviour if it isn't windows compatible). This makes clj-ssh.cli unusable but clj-ssh.ssh is fine with the fix
(ssh-agent {:use-system-ssh-agent false})
If you do want to use a system ssh-agent, the readme for clj-ssh and ymnk below mention PuTTY's pageant, I couldn't find any info on setting this up but it should be doable with cygwin.

I've seen this if the SSH_AUTH_SOCK environment variable is set. Clearing this environment variable before starting the jvm might solve the issue.
When SSH_AUTH_SOCK is not set, clj-ssh should automatically use pageant if it is running.
Looks like the best solution would be to support NCUSocketFactory as per ymnk's commit, and add documentation about cygwin's ssh-agent. Happy to take a pull request for that.

Wrapping a jar file in a Windows service

Have you had experience with running a jar file using a command line, wrapped in a Windows service?
I'm trying to find a way to run a jar file without being logged into the machine, and since it allows command shell, I was wondering if it's a good idea.
Thanks!
Original Post:
I'm trying to run Associated Press's Web Feeds Manager, which is basically a jar file that can be run when logged in by double clicking it.
I'd like to run the same file but without being logged in to the machine. In their manual (http://wfm.ap.org/admin/content/help/Running_Agent_on_a_Remote_Server.htm) they write how to do that, using a commandline parameter.
Basically I'd like the jar to run as a Windows service, regardless of who's logged in, but Googling it showed it was problematic.
Have you had experience with remotely running jar files? What are the pitfalls?
Thanks!

On a google search, I came across this article -
Running Jar Applications as a Windows Service
It mentions about open source Java Service Wrapper project from Tanukisoftware.org for accomplishing this task.
Note: I've not used this personally.

If you are not interested in having the service started/stopped at boot/shutdown, but you just want the program to be started manually and keep running after logout, here is what you do:
$ nohup java -jar foobar.jar > foobar.log 2>&1 &
which means: start my foobar.jar (java -jar) and keep it running after I logout (nohup) redirect stdout to foobar.log (>) and also the stderr (2>&1), and make it running in background (& at the end).
Instead, if you are interested in installing a "service" in your linux box, there are many options, depending on what distribution you are using.
The most common are upstart (for ubuntu) and System V init scripts (Redhat or others). Also cron can be used to start/stop services at startup/shutdown.
You can find an example of installing a java app (hudson) on an init system here, or doing the same thing with upstart. Or, as I said, cron could be an option.
On Windows, there is Java Service Wrapper. And not much more.

For windows Java Service Wrapper is a better choice

My favourite is the upstart on linux, but it is Ubuntu only.
On Windows I see many alternatives according to this forum.

Need help running visualvm on Windows when under VMWare

I am doing some Java development on Windows 7 x64 running inside VMWare Fusion 3.x (OSX). I have installed JDK6 (update 26), set JAVA_HOME to the path (no trailing slash), and restarted my command prompt.
I can successfully launch the program. During startup it runs the calibration and then fails with this error:
"Could not create directory\VMWare-host\Shared Folders\ .nbprofiler" (no space after that slash but the markup was hiding the period)
I can click to continue, but when I'm in the program I cannot do CPU or Memory profiling. I throws up a similar error box:
"Error retrieving saved calibration data for target JVM: Could not create...(same as earlier)"
Once upon a time I had this working by passing the --userdir flag and -J-Dnbprofiler.home during startup, but that trick isn't working anymore.
(The complete command was:
jvisualvm --userdir c:\Users\myname -J-Dnbprofiler.home=c:\Users\myname
)
How can I force jvisualvm to save its calibration data on a "real" drive instead of the vmware network drive and get this working?

.nbprofiler directory is derived from user.home system property. I am not sure what you did to Windows installation, but your user.home points to directory\VMWare-host\Shared Folders. So one solution is to fix the Windows installation, so that Java recognize c:\Users\myname as your user home directory. If that fails for some reason you can use nbprofiler.home property to override it, as you correctly wrote. However you should point it to the nonexistent directory, so you should start VisualVM with the following commandline:
jvisualvm -J-Dnbprofiler.home=c:\Users\myname\nbprofiler --userdir c:\Users\myname\visualvm_userdir
One last note, even if the profiler part is not working, you should be able to use sampling in the 'Sampler' tab.

Try disable Sharing for the VM.
It works for me with Windows 7 x86 in Fusion with Sharing disabled (and Sharing is the mechanism providing the folder you cannot write to).

I found the following command works for me.
visualvm -J-Duser.home=%HOME%
Also, I needed to add -Duser.home=%HOME% to my app startup command.
I had defined nbprofile.home and userdir, but I was still getting an error when the Profiler was running against my app: Profiler Agent Error: Could not create directory\vmware-host\Shared Folders.nbprofiler.
I discovered that the Profiler was using user.home defined by my app rather than the one with visualvm. Both seem to be needed.
