I thinks it is some problems in my java installation but i don't know what is the problem and how can i fix it
I can run jar file with openjdk in visual mode but in terminal i cannot run jar files
for example you can see this below
root#mohammad-Inspiron-1564:/media/storage/Linux/Freedom# java -jar freedom.jar

perhaps i should re-install mu kubuntu :((
thnx

The error message tells you that it cannot connect to the X11 window server. The program in the JAR file uses Swing and needs some way to display the GUI it creates. If you have X11 installed, you can start it from the command-line by typing startx. Otherwise you need to install it or some other system that will allow you to run a Swing-based program.

I have been trying to install/run JavaFX18 from Gluon on my raspberry pi4 and getting the following error message:
Exception in thread "main" java.lang.reflect.InvocationTargetException
at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
(... edited...)
Caused by: java.lang.UnsatisfiedLinkError: /opt/javafx-sdk-18/lib/libglass.so: /opt/javafx-sdk-18/lib/libglass.so: undefined symbol: g_direct_hash
here is my config:
Java: Linux/arm32 jdk-17.0.1+12
JavaFx: Linux/arm32 openjfx-18-ea+7 (also tried 17.0.1 and 17.0.2)
I'm following the instruction per Gluon doc (https://docs.gluonhq.com/#platforms_embedded) using the simple HelloFX example (https://github.com/openjfx/samples).
Here are the commands I'm executing in the HelloFX directory (where src is) on my pi:
sudo /opt/jdk-17.0.1+12/bin/javac -verbose
--module-path=/opt/javafx-sdk-18/lib --add-modules=javafx.controls src/hellofx/HelloFX.java -d dist
sudo /opt/jdk-17.0.1+12/bin/java -Dglass.platform=gtk -Djava.library.path=/usr/java/packages/lib:/lib:/usr/lib:/opt/javafx-sdk-18/lib
--module-path=/opt/javafx-sdk-18/lib --add-modules=javafx.controls -cp dist/. hellofx.HelloFX
[Note this is running with X11, not in Kiosk/CLI mode; the Gluon doc also shows how to run that same example in non-desktop mode with DRM..etc: I have tried this and working reasonably ok; I haven't tried the 64b variant yet]
has anyone stumbled on this issue and able to work around?
FWIW: Certainly not a good solution with unknown side effect: I used the libglass.so from JavaFX11 SDK replacing that same file in JavaFX17.0.1/lib and the HelloFX example works launching from the desktop.
so... either there is a bug in the FX 17.0.1/17.0.2 and 18 Linux/arm32 SDKs with that libglass.so file or some obscure settings are required.
Greetings
I have deployed a simple JavaFX application using msi installer that was created by jpackage. When double-clicking on the application icon installed in Windows 10 "program files" directory, it displays an error "Failed to launch JVM". Prior to deployment, I tested the application jar file from the command prompt without any problem. When checking the application installation directory (under "C:\Program files") it has all the runtime dlls and so on, so I am not sure what causes this error? Here is the japckage command I used to build the runtime image:
jpackage --type msi --name FileChooser -p "%JAVAFX_HOME%\lib;%M2_REPO%;org\openjfx\mavenfxfilechooser\mavenfxfilechooser.jar" --module "org.openjfx.mavenfxfilechooser/org.openjfx.mavenfxfilechooser.FileChooserApp"
Update
Following the recommendation given in the comment section, I installed the JMODS on my machine and issued a jpackage command line to point to the JMODS files instead of JAVAFX_HOME as follow:
jpackage --type msi --name FileChooser -p "%JMODS_HOME%;%M2_REPO%;C:\Users\hrh74\Downloads\Lib\file\org\openjfx\mavenfxfilechooser" --module "org.openjfx.mavenfxfilechooser/org.openjfx.mavenfxfilechooser.FileChooserApp"
I installed the application using the MSI runtime image and this certainly solved the" Failed to launch JVM" problem. The application started, however, I have a WebView component that should display content from https://us.yahoo.com when the user clicks on a "Yahoo" button and this doesn't seem to be working when the application run as a self-contained app but it works when I run the jar file from the command line. Do I need to add anything to the jpackage?
Please let me know if the source code and FXML file are needed.
Thanks
Your original problem has to do with missing native code. But you appear to have already solved that problem by using the JMOD files for JavaFX provided by Gluon. So I'll try to help solve your other issue regarding https://us.yahoo.com not loading in the WebView once you create a self-contained application.
When trying to load that website myself I was running into the same issue as you. Though sometimes I'd get a "we're working on the problem" page response, other times the entire application would become unresponsive, and yet other times nothing would happen (the load would just seem to fail "gracefully"). This happened with other websites as well, not just Yahoo. After some testing I was finally able to get the following error:

That indicated to me the application created by jpackage was missing some crypto libraries. From here I just guessed, but inclulding:
--add-modules jdk.crypto.cryptoki,jdk.crypto.ec
When running jpackage seemed to solve the problem. I don't know if both modules are needed, or if only one is needed (or if adding either one implicitly adds the other).
Side note: When scrolling through https://us.yahoo.com I would frequently get the following warnings:
Mar 05, 2021 12:10:40 PM com.sun.javafx.webkit.prism.WCMediaPlayerImpl onError
WARNING: onError, errCode=0, msg=Could not create player!
And:
Mar 05, 2021 12:10:41 PM com.sun.javafx.webkit.prism.WCMediaPlayerImpl$CreateThread run
WARNING: CreateThread ERROR: java.lang.UnsupportedOperationException: Unsupported protocol "data"
I would get that warning regardless of how the application was packaged. I don't know how to solve the problem, or if there even is a solution without modifying the JavaFX code itself.
Have you seen running JavaFX application after jpackage? Try to download Gluon jmods and use it instead of %JAVAFX_HOME%
I get the following error when trying to run my simple java class with ikvm on Windows.
Exception in thread "main" java.lang.UnsupportedClassVersionError: dummy (52
.0)
at IKVM.NativeCode.java.lang.ClassLoader.defineClass1(Unknown Source)
...
at IKVM.NativeCode.java.lang.Class.forName0(Unknown Source)
at java.lang.Class.forName(Class.java:361)
Since I am able to run the same class on my Mac with mono - it shouldn't be a the JDK version (which is 1.8). I have checked the classpath, which directs to the /lib directory of ikvm and the current directory.
Both ikvm and ikvmc won't work on Windows Server 2012. Everything is accessible - javac, csc, ikvmc. I get the classpath just fine with echo %CLASSPATH%.
I am missing something here - but what? I have been searching and reading through the mailing list; it's apparently the most asked question to be mentioned in the FAQ, but I don't see the next steps of troubleshooting this.
Thank you for your help!
I have built a Camel project in Eclipse with Maven dependencies.
It ran successfully and also Built the Jar file and ran it from the command prompt
which is running as required. But when I moved the JAR file onto to our Linux machine
which is like a Job Manager server and when I try to run the JAR file as below
I am getting the below error message.
When I try to run with the below command
$ java –jar mycamelproject
I am getting the below error, but I do have the below mentioned dependency in the Dependency-Jars folder.

Then I tried running with the below command.
$ mvn -X exec:java -Dexec.mainClass=mycamelpackage.mycamelmainclass
I am getting a series of the below errors such as below

How should java –jar mycamelproject work if no classpath is set? And mycamelproject should be a JAR file anyway (and if it is, you should add the *.jar extension).
Beside that, I guess your local Maven repository may be corrupt. That's usually the reason why you see the resolution will not be reattempted error message. The easiest way to fix this is to remove the corrupt directories and start Maven again.
I'm having trouble running a custom jar on Elastic Map-Reduce
I'm using jdk1.6.0_26, Hadoop 0.20.205, and compiling with Eclipse on my computer and everything works perfectly fine
for example if I ran the following on my computer it would be successful
hadoop jar MaxTemperature.jar input/temperature.txt output
I specified the jar as the following on AWS
s3n://chrishadoop/MaxTemperature.jar
and I specified the arguments as
s3n://chrishadoop/input/temperature.txt s3n://chrishadoop/output
I did not specify the main class because I pointed to it in the manifest
Here is the jar I'm using, I will make it public for a little while
https://s3.amazonaws.com/chrishadoop/MaxTemperature.jar
Here is the error I'm getting

There is a version of Jackson which is installed as part of the AMI, and I'm guessing you're bundling a different version of Jackson? The error seems to be happening in the support code which makes "enable debugging" work.
