I work with eclipse.
Part One:
I've got 2 projects.
Project A is a simple FX-Dialog (Java-Controller and fxml-File). There is
no main in it.
package: info.azo
Project B is a databased FX-Application (main)
package: ch.muellner
I want to load the login dialog of project A in project B
I do it this way, but the error is: 'Location not found'
FXMLLoader loader = new FXMLLoader();
loader.setLocation(Main.class.getResource("info.azo/Login.fxml"));
AnchorPane anchorPane = (AnchorPane) loader.load();
My path to fxml is not correct, what is the correct syntax?
Part Two:
Project A is also a JAR-File, I could load this from Project B, but how?
This works perfect for me: if the jar-file of Project A is in JavaBuildPath of Project B.
loader.setLocation(Main.class.getResource("/info/azo/Login.fxml"));

Need some clever advice to solve this - well, some kind of problem while using simple JavaFX app.
However, there was some problems while all is set-up (module path, for example), but what now when I just cannot run .jar file from terminal? Ok, start talk about mission-impossible-with-javafx:
I got Apache NetBeans 12 installed on Linux Mint 20. JDK is already installed, so 'java -version' returns 'openjdk version "11.0.7" 2020-04-14'...
When start project there is no problem at all - JavaFX app works.
I need this app to work on Windows 8.1, but before that I tried to run this .jar file on my linux terminal using java -jar MyFile.jar.
Here the problem starts: it said no main manifest attribute, in MyFile.jar.
Then I decide to set the main class directly in jar file (opened using Archive Manager):
MyFile.jar -> META-INF -> MANIFEST.MF and add on last line: Main-Class: mypackage.MyClass
Now I have: Error: Could not find or load main class mypackage.MyClass Caused by: java.lang.NoClassDefFoundError: javafx/application/Application
Ok, how and why?
Just to said that in NetBeans I also set main class in:
Project -> Properties -> Run -> Main class: mypackage.MyClass
and in VM options I added:
--module-path "/locationToJavaFX/javafx-sdk-11.0.2/lib" --add-modules javafx.controls,javafx.fxml
In pom file, main class is also set (generated by IDE):
// other lines
<groupId>org.openjfx</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>0.0.4</version>
<configuration>
<mainClass>mypackage.MyClass</mainClass>
</configuration>
// other lines
and module-info looks like:
module mypackage {
requires javafx.controls;
requires javafx.fxml;
requires org.jsoup;
opens mypackage to javafx.fxml;
exports mypackage; // some people advice without this line, I tried but same problem
}
Just want to be clear - I tried probably everything (I don't count) that is available here on stackoverflow. I try to fix this yesterday and today (almost 2 whole days) and I can't.
Just a thought: Java programming is not so difficult as configuration is.
Cheers and thanks for helping!
EDIT:
Just to said that I tried what José suggested : first creating launcher class, follow 'fat jar' step-by-step then run 'semi-fat jar' command which he added to the post. Interestingly enough, this return me: Error occurred during initialization of boot layer java.lang.module.FindException: Module javafx-fxml not found. Why not found javafx-fxml if I aready defined it as said above in question? Also, why Netbeans doesn't provide me the main class in manifest (in jar) file? When I add main class in manifest, I get this:

Ok, how Application does not found? :)
EDIT 2:
Yeap, mister José has a right. This command in his 'semi-fat jar' post actually works BUT not for Maven (I use it on same Ant project and it works). Maven somehow cannot recognize JSoup class (even I add it in dependency) and java returns:

Hope I'll find solution for Maven projects in the near future.
Yeah I noticed you use maven but it's not fault of maven, I know why this happen and i have solution about it so in my solution there is magic and work fine because i use my solution to make jar and you know my jar file run without terminal(means double clicking on jar file)
Solution
you need winRar because i use it for info read my solution!
Just follow below step with images to run jar(both maven and gradle project)
solution of Error: Could not find or load main class mypackage. this line
you created main class at this location /src/main/java/YOUR_PACKAGE_NAME/Main.java so while creating jar file intellij couldn't care your main class if you create main class at above location and it doesn't add Main-Class: Main this line in Manifest File Solution is that create one more main class(don't delete Main.Java class we use this class in new one main class) at this location /src/main/java/EntryPoint.java see below image and code what i did
EntryPoint.java is new main class (IMAGE)
public class EntryPoint {
public static void main(String[] args) {
smartSeizeing.Main.main(args);
}
}
Main.java Image
Main.Java (IMAGE)
After creating EntryPoint.java(New Main Class) Manifest File For Jar File, clicking Cntr+Alt+Shift+S to create Manifest File | Jar File, during creating jar file(before build jar) Just select EntryPoint.Java As Main Class Below Image
Main Class : EntryPoint (IMAGE)
Before click Ok button change the location of manifest file create it at this location /src/META_INF/manifest.mf(Wrong location : /src/main/META_INF/menifest.mf) and click Apply button to save changes
Location Of Manifest File like below image
Just Manifest.MF File (IMAGE)
Build Jar file go to Option[Build->Build-Artifacts...] and take 3-5 min to create jar.
After Creating Jar file Please Read clearly this main step means
Means Solution Of This line of NOT FOUND FXML FILE this is tricky because all fxml file are stored at resource directory so while creating jar so intellij doesn't add the any file from resource directory again not include fxml file while creating jar
Solution Of How to include FXML FILE NOW WE HAVE TO USE WIN_RAR Software To Add This File And Believe Me Its work and not affect any file and work file Just Follow below step to add FXML FILE
Adding FXML FILE STEP
close Intellij
Go to your project Directory in my case C:\Users\ADMIN\IdeaProjects\YOUR_PROJECT_NAME and Go to YOUR_PROJECT_NAME\out\artifacts\YOUR_PROJECT_NAME\YOUR_PROJECT_NAME.Jar so u find jar file of your project
Just click right key of Mouse for option, select option of EXTRACT HERE(WinRar Option)
JUST I AM ExtractING MY JAR (IMAGE)
DELETE ONLY JAR FILE AFTER EXTRACTING Like my file name smartSeizeing.jar i delete it (IMAGE)
After extracting and deleting jar(only jar file) file so OPEN YOUR_PACKAGE_NAME File in My case C:\Users\ADMIN\IdeaProjects\SmartSeizeing\out\artifacts\SmartSeizeing_jar\smartSeizeing
Keep Open It And Open Your Project directory and copy all file(including all file like fxml, css, html, hibernet file if u have other file to with fxml) from resource directory and Paste all file(copied Files) in that previously open folder(extract jar folder like IdeaProjects\YOUR_PROJECT_NAME\out\artifacts\YOUR_PROJECT_NAME_jar\YOUR_PACKAGE_NAME) And after coping file so and just make jar file select all file(IdeaProjects\YOUR_PROJECT_NAME\out\artifacts\YOUR_PROJECT_NAME_jar) and click right key of mouse, select add to archive(WinRar) and after creating YOUR_PACKAGE_NAME.jar file just double click that file and see the magic
How to Add fxml and how to create again jar(without any curreption) i mentioned in below image so u can easily understand what i did and also image of my OUTPUT
i pasted all file of resource directory of my project (IMAGE)
Please see below answer too because i can't add more link for step of how to make jar using winRar and that jar work fine and also my output
Best Of Luck
and You wanna video just tell me i make video about it How to make runnable jar without any exception or error!
this is because i can't add more links that's why i again wrote this
WinRar to create Jar File
Continue From Previous Answer and image that is https://i.stack.imgur.com/fY1tw.png
this is what i copy from Resource folder of my project
just paste of all file of resource directory at (in my case) C:\Users\ADMIN\IdeaProjects\SmartSeizeing\out\artifacts\SmartSeizeing_jar\smartSeizeing
WinRar to make Jar follow bellow step (IMAGE)
Step 1
Step 2 select zip option then change extension of your file .zip to .jar
Step 3
This is what i am trying to explain to you and this is my Output
i hope you understand what i do for creating jar file
I am trying to add a library like jfoenix-9.0.8 into scene builder (8.5.0). I am using java version 1.8.0_201 on Windows 10.
What I try in JAR/FXML Manager:
- Search repositories
- Manually add Libray from repository
- Add Library/FXML from file system
What happens:
- At begin, installed Library/FXML File list is empty
- I choose the library
- Import Dialog is open with no items an button "Import Jar (no UI components)
There is no error message pop up.
I have developed a javafx application that reads the database configuration properties from a ".properties file".When i run the app in eclipse everything works fine.The problem is when running the app from the generated executable jar,it throws me a NullPointerException because it cant read the ".properties file".
The code is :
FileInputStream fis=new FileInputStream("resources/META-INF/db/db.properties");
Properties properties = new Properties();
properties.load(fis);
I searched about this and i saw some examples of using InputStream :
Properties pp = new Properties();
InputStream is = getClass().getClassLoader().getResourceAsStream("errors.properties");
pp.load(is);
But still doesnt work.Any idea?strong text
Try creating a folder that you always have with you Jar. The folder name should be resources. This folder should have a folder named META-INF. META-INF should have a folder named db. Finally, db should have the db.properties file in it.
Problem:
Changing two lines of code makes the executable jar go from opening and working perfectly to not opening (even though it runs in Eclipse).
Description:
I have made an application in JavaFX using local file directories (silly I know) to access a .jpg file and I can deploy it as an executable and it works great on my computer using this code snippet.
Obviously, another computer will be unable to access my files so I converted the files into a more universal form so anyone who uses the application would be able to view the file.
A problem arises somehow when I create a .jar executable. The .jar opens and works great when using the absolute path but when I change only 2 lines the .jar executable will not open.
Here is the full code.
package workingSamples;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class ImageDisplay extends Application {
#Override
public void start(Stage stage) {
stage.setTitle("HTML");
stage.setWidth(500);
stage.setHeight(500);
Scene scene = new Scene(new Group());
VBox root = new VBox();
final ImageView selectedImage = new ImageView();
File file = new File( "C:\\Users\\Documents\\logo.jpg" );
Image image1 = new Image( file.toURI( ).toString( ), 500, 200, true, true );
//Image image1 = new Image(ImageDisplay.class.getResourceAsStream("logo.jpg"), 500, 200, true, true);
selectedImage.setImage(image1);
root.getChildren().addAll(selectedImage);
scene.setRoot(root);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
This .jar executes and opens with no errors but if I uncomment the one commented line (and comment out the two above it) the project works in Eclipse but it will not open any time when I export as an executable. And I get this error every time when I try to export it:
Exported with compile warnings: WorkingSamples/src/workingSamples/ImageDisplay.java
I have tried storing the data in both the bin and src, restarting Eclipse, making sure Debug mode is not running, trying every type of library handling. Maybe it is a permission issue but I do not know how to try to fix that.
Any help would be greatly appreciated! Thank you in advance :)
(I have tried the fixes from javafx jar builds fine but doesn't open (unfortunately I do not have command line access due to company security constraints) and Can't run javafx JAR outside Netbeans (I don’t believe there are any libraries that need to be imported but are not) and Unable to run Javafx from computer by double clicking the jar file (I have the latest version of Java installed) and Eclipse - error executable jar file (I tried all library handling options but maybe it’s a permission issue which I do not know how to fix))
Code inspired from this example:
ANT file output:
<?xml version="1.0" encoding="UTF-8"?>

The base directory of getResourceAsStream(...) is your jar root. I would suggest to place your image into a resource folder (in your case) WorkingSamples/resources/logo.jpg afterwards you can access the image with
Image image1 = new Image(ImageDisplay.class.getResourceAsStream("/resources/logo.jpg"), 500, 200, true, true);
Another thing you can check is if the ant script puts the image into the right place inside of the jar
I have a TestNG project. Don't have any main class, currently it is running like "Run As TestNG".
I want to export it as runnable jar or jar so that any one can just hit a command from command line and test cases start running.
Could any one help me out in this? or suggest any other way to deliver the code in runnable form...
I am not using ant or maven.
Thanks
I seem to have found the solution after a bit of googling. This works fine in Eclipse (Juno).
Say, you have a TestNG file named 'Tests.java'. As you rightly pointed out, there won't be a class with main method.
So, we have to create a new Java class file under the same package. Let us name it 'MainOne.java'. This will have a class with main method.
Here is the code you need:
import com.beust.testng.TestNG;
public class MainOne {
public static void main(String[] args) {
TestNG testng = new TestNG();
Class[] classes = new Class[]{Tests.class};
testng.setTestClasses(classes);
testng.run();
}
Run the 'MainOne.java' as a Java application. Then right click on the package -> Export -> Runnable Jar [Choose 'MainOne' as Launch Configuration] -> Finish.
My current understanding is that, in order to benefit from the parallel niftiness of TestNG, one should use the static main method in org.testng's jar file when running the Java class from the command line rather than from inside Eclipse IDE.
The issue then becomes classpath, which defines how java finds all the JAR files. I found http://javarevisited.blogspot.com/2012/10/5-ways-to-add-multiple-jar-to-classpath-java.html to be most useful because it has the * wildcard mentioned --- VERY helpful when you need to reference all the jar files required for Selenum + TestNG + custom test suites.
This is my current Windows BAT file, and it works. ADV.jar contains my custom class but no main method.
setlocal
set r=d:\Apps\Selenium\
cd /d %~dp0
java -classpath %r%Downloaded\*;%r%MyCompany\ADV.jar; org.testng.TestNG .\testng-customsuite-adv.xml
pause
All the JAR files that I downloaded from public places went into my d:\Apps\Selenium\Downloaded folder. I put my custom ADV.jar file in d:\Apps\Selenium\MyCompany to keep it separate.
I created my ADV.jar file from Eclipse using Export Jar file and ignored warnings about a missing main method.
Aside: while this https://stackoverflow.com/a/16879386/424855 was very intriguing, I could not figure out how to make that work.
Here is the better way to do it.
You can just create a main method which will have list of all test classes to be executed as follows:
public static void main(String[] args) {
TestListenerAdapter tla = new TestListenerAdapter();
TestNG testng = new TestNG();
testng.setTestClasses(new Class[] { test_start.class });
testng.addListener(tla);
testng.run();
}
Here is the reference URL from the official testng website.
Run the MainOne.java as a Java application. Then right click on the package -> Export -> Runnable Jar [Choose MainOne as Launch Configuration] -> Finish.
