When trying to run my class file, this is the source
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import java.util.concurrent.Executor;
public class TestApplication extends Application{
#Override
public void start(Stage stage) throws Exception {
new TestApplication();
}
public TestApplication() {
try{
final Parent root = FXMLLoader.load(Executor.class.getResource("test.fxml"));
final Stage stage = new Stage(){{
setScene(new Scene(root, 300, 250));
setTitle("Test");
setResizable(false);
show();
}};
}catch(Exception e){
e.printStackTrace();
}
}
}
The fxml file contains a simple gui.

I've worked on this very same issue for the past few hours. Even though I haven't seen it written explicitly, it appears that you MUST use one of the JavaFX packaging tools, which is either an Ant task or the javafxpackager executable. (See http://docs.oracle.com/javafx/2/deployment/packaging.htm, section 5.3.1). The NetBeans IDE uses Ant to package the code. (I'm using IntelliJ)
When you use one of those packaging methods, in addition to all of your application's code and resources, it also adds the following to your output JAR file:
/com/javafx/main/Main$1.class
/com/javafx/main/Main$2.class
/com/javafx/main/Main.class
/com/javafx/main/NoJavaFXFallback.class
With these in place, you can run the app from the command line:
java -jar outjar.jar
and all works fine. If I remove the extra com.javafx.main files, the app does not run.
To double-check this, I looked at all four JAR files in the JavaFX samples (BrickBreaker, Ensemble, FXML-LoginDemo, and SwingInterop). They all have the "extra" files, too.
For my small test app, I used this command line to build an "executable" JAR file:
javafxpackager -createjar -appclass sample.Main -outfile outjar -v -nocss2bin -srcdir C:\workspaces\garoup1\out\production\javafx1
Hope this helps!

I had the same problem and below steps helped me to solve it,
Adding the vm arguments while running the application,
--module-path /home/user/Java-libraries/openjfx-11.0.2_linux-x64_bin-sdk/javafx-sdk-11.0.2/lib/ --add-modules javafx.controls,javafx.fxml
Note:
The --module-path will contain the jars of Java fx
I used open-jdk 13
Configure this in your eclipse (If you are using so) or you can just compile and run like,
Compile
javac --module-path /path/to/java-fx-libs/ --add-modules javafx.controls,javafx.fxml *.java
Run
java --module-path /path/to/java-fx-libs/ --add-modules javafx.controls,javafx.fxml MyMainClass

I believe that my example will help someone. I had not succeeded with building REALLY executable jar file, that can be run by click from any place/directory with Java 8. Moving to Java 11 and few other twicks did the business.
Move to Java 11. Specify SDK, other staff in IDE, add this to pom.xml
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>

The jar file with specified name will appear in target directory. It will be executable independent from where you are running it.

Using java 8 shouldn't give this problem but it did for me
I created my jar initially from Eclipse Export -> Runnable Jar and it was fine. When I moved to Maven it failed with the above.
Comparing the two jars showed that nothing fx related was packaged with the jar (as I'd expect) but that the Eclipse generated manifest had Class-Path: . in it. Getting maven to package the jar with the following worked for me (with Java 8)
<build>
<plugins>

I know it may not be the "proper" way of launching an javafx application but i have struggled with this problem for some time and came up with a workaround that does not require to use any external packaging applications, force you to use ant or maven plugin (which conflicts with the shade plugin) etc...
The solution uses Utils4j to load jfxrt dynamically at runtime. You cannot load it in a class extending javafx.application.Application, do it in a separate class and name it for example: Launcher
import org.fuin.utils4j.Utils4J
public class Launcher {
public static void main(String[] args) {
Utils4J.addToClasspath("file:///"+System.getProperty("java.home")+ File.separator+"lib"+File.separator+"jfxrt.jar");
// CODE TO RUN YOUR CLASS THAT EXTENDS javafx.application.Application goes here.
}
}
you can include Utils4j with your project (if using maven):
<dependency>
<groupId>org.fuin</groupId>
<artifactId>utils4j</artifactId>
<version>0.7.0</version>
</dependency>

I use maven and I just run this mvn install:install-file -Dfile="/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre/lib/jfxrt.jar" -DgroupId=com.oracle.javafx -DartifactId=javafx -Dversion=2.2 -Dpackaging=jar in terminal(Maybe a little difference in Windows.). Then maven will install jfxrt.jar then you can simply reference it as
<dependency>
<groupId>com.oracle.javafx</groupId>
<artifactId>javafx</artifactId>
<version>2.2</version>
</dependency>

If you are using netbeans like me and you have two versions of JDK installed, then you should change the classpath to the appropriate java installation in the config file. This is also a bug in Netbeans:
There are two ways to do it:
Either start NetBeans with --jdkhome by executing this:
"C:\Program Files\NetBeans Dev 201402160001\bin\netbeans.exe" --jdkhome "C:\Program Files\Java\jdk1.7.0_51"
Or set the "netbeans_jdkhome" property in /etc/netbeans.conf e.g.
# Default location of JDK, can be overridden by using --jdkhome <dir>:
netbeans_jdkhome="C:\Program Files\Java\jdk1.7.0_51"

IntelliJ and maybe other IDE's do not refactor your Run/Debug configuration. You must manually change your package name preceding the name of your Main class. For instance, change 'sample.Main' to 'com.company.package.ui.Main' so it will launch correctly next time you try to run it. The IDE might have already marked the Run/Debug button with a red cross because it couldn't find the main class. It also gives a warning when you open the Run/Debug configuration.

I already answered it on "Ask ubntu".
I recommend you to go with https://openjfx.io/openjfx-docs/ .i am using Eclipse IDE but it works for all IDE
Then you can refer to this global variable when setting the VM options as:
In IDE Right-click on project->Run As -> Run Configuration ->Arguments->VM Arguments
For Windows,
--module-path "\path to javafx\lib" --add-modules javafx.controls,javafx.fxml
For Linux,
--module-path /path to javafx/lib --add-modules javafx.controls,javafx.fxml

I'm developing on Linux a simple WebApp i got the same error, but is really easy to fix it (assuming you are developing on the command line as myself).
cat compile.sh
#!/bin/bash
/usr/lib/jvm/jdk1.7.0_25/bin/javac WebViewSample.java -cp /usr/lib/jvm/jdk1.7.0_25
/jre/lib/jfxrt.jar
$ cat run.sh
#!/bin/sh
JAVA_HOME=/usr/lib/jvm/jdk1.7.0_25/bin/

$JAVA_HOME/java -cp $CLASSPATH WebViewSample $* 2>&1 /dev/null | awk -F\| '{ print $2"|"$3 ; exit $1 }'
exit $?

I had a problem of not finding the Pair class from javafx.
It seems that vanilla eclipse (without the e(fx)clipse extension) doesn't search the javaFX runtime jar included with java.
I just added to my eclipse project build path this external jar (or if you are in a debug configuration, add the external jar in the JRE tab of the debug configuration):
$JAVA_HOME/jre/lib/ext/jfxrt.jar
(replace JAVA_HOME with your jdk folder)
For me it was in /installs/jdk1.8.0_211/jre/lib/ext/jfxrt.jar

in eclipse environment: add jfxrt.jar to Bundle-ClassPath in MANIFEST.MF file.
Bundle-ClassPath: .,
jfxrt.jar

How to use Apache Tattletale to analyze duplicate Jar/APIs used in class path

In my project they have used more than 225+ jar files which causing memory issue, while searching on net i come to know Apache Tattletale will analyze and give a report of duplicate classes and JAR/APIs used by the application (Classpath). So i have refereed following links
1) how to use JBoss Tattletale tool
2) Uncover JBoss client jar list with Tattletale
3) Jboss official Documentation
but i didn't get how to execute and run the Tattletale Jar file and my application is not based on maven so i am not using Maven.
I have downloaded tattletale-1.2.0.Beta2.jar file along with jboss-seam-2.3.0.CR1-dist file and used following command
java -Xmx512m -jar tattletale.jar /Java/workspaces/mycoolprojects/projectX output-projectx
but getting following exception

More over i didn't get what is the use of jboss-seam-2.3.0.CR1-dist file. Meaning i can see lot of jar files and lot of code in there but i don't know how does it help to use tattletale.
In the official documentation they have mentioned jboss-tattletale.properties and how can i set/use that.

I was having the same problem and this solution worked for me too.
(downloaded the latest javaassist jar)
Interestingly, tattletale itself suggests that the tattletale jar contains the
javaassist jar

The below steps worked for me:
download jboss-javassist-javassist-rel_3_22_0_cr1-2-g6a9079a.zip from http://jboss-javassist.github.io/javassist/
extract it to a location
go to that location and copy javassist.jar
go to location where your tattletale-1.2.0.Beta2.jar is present
paste javassist.jar here
open command prompt at this path
run command java -jar tattletale-1.2.0.Beta2.jar path_to_application_archive output_path

I inherited an old Maven project configured to use this plugin and got the same javassist errors. The plugin dependencies may be adjusted as shown to make the errors stop.

How to add jars to JMeter's classpath in non-GUI mode

I have created a test plan in the JMeter GUI which uses the "Java Request Sampler".
I added the jarfile which contains the implementation to my sampler to /lib/ext/ of my jmeter installation.
This all works fine when I run it in GUI mode.
However when I switch to non gui mode using
./jmeter -n -t Test\ Plan.jmx
I get:

I have no clue why this behaves differently when using -n -t. Does anybody have a solution to this?
I work on Linux using openjdk if this is somehow a helpful information.

As per How do I run JMeter in non-gui mode article you can use -J key to provide additional classpath elements location to JMeter like below:
./jmeter -Juser.classpath=/some/folder/your/extension.jar -n -t ${path_to_your_script} -l ${path_to_results}

Put the jar in jmeter/lib folder.
lib/ext is for real plugins.

Below is how I have the plugin set-up for maven pom
<plugin>
<groupId>com.lazerycode.jmeter</groupId>
<artifactId>jmeter-maven-plugin</artifactId>
<version>2.7.0</version>
<executions>
<execution>
<id>jmeter-tests</id>
<goals>
<goal>jmeter</goal>
</goals>
</execution>
</executions>
<configuration>
<testPlanLibraries>
<artifact>org.apache.commons:commons-lang3:3.0</artifact>
</testPlanLibraries>
<propertiesSystem>
<user>${username}</user>
</propertiesSystem>
</configuration>
</plugin>

I had the same issue today with jmeter 5.4 on a linux machine.
Thanks to my colleague we identified the root cause.
In jmeter.properties we use the following line to extend the classpath libs.
user.classpath=../lib;../lib/ext
Howerver on a linux machine this line hast to be look like:
user.classpath=../lib:../lib/ext
Thus use : instead of ;
In our case this fits our problem.

Add it as a dependency inside the jmeter plugin:
<dependencies>
<dependency>
<groupId>postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.0-801.jdbc4</version>
</dependency>

When trying to run my class file, this is the source
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import java.util.concurrent.Executor;
public class TestApplication extends Application{
#Override
public void start(Stage stage) throws Exception {
new TestApplication();
}
public TestApplication() {
try{
final Parent root = FXMLLoader.load(Executor.class.getResource("test.fxml"));
final Stage stage = new Stage(){{
setScene(new Scene(root, 300, 250));
setTitle("Test");
setResizable(false);
show();
}};
}catch(Exception e){
e.printStackTrace();
}
}
}
The fxml file contains a simple gui.

I've worked on this very same issue for the past few hours. Even though I haven't seen it written explicitly, it appears that you MUST use one of the JavaFX packaging tools, which is either an Ant task or the javafxpackager executable. (See http://docs.oracle.com/javafx/2/deployment/packaging.htm, section 5.3.1). The NetBeans IDE uses Ant to package the code. (I'm using IntelliJ)
When you use one of those packaging methods, in addition to all of your application's code and resources, it also adds the following to your output JAR file:
/com/javafx/main/Main$1.class
/com/javafx/main/Main$2.class
/com/javafx/main/Main.class
/com/javafx/main/NoJavaFXFallback.class
With these in place, you can run the app from the command line:
java -jar outjar.jar
and all works fine. If I remove the extra com.javafx.main files, the app does not run.
To double-check this, I looked at all four JAR files in the JavaFX samples (BrickBreaker, Ensemble, FXML-LoginDemo, and SwingInterop). They all have the "extra" files, too.
For my small test app, I used this command line to build an "executable" JAR file:
javafxpackager -createjar -appclass sample.Main -outfile outjar -v -nocss2bin -srcdir C:\workspaces\garoup1\out\production\javafx1
Hope this helps!

I had the same problem and below steps helped me to solve it,
Adding the vm arguments while running the application,
--module-path /home/user/Java-libraries/openjfx-11.0.2_linux-x64_bin-sdk/javafx-sdk-11.0.2/lib/ --add-modules javafx.controls,javafx.fxml
Note:
The --module-path will contain the jars of Java fx
I used open-jdk 13
Configure this in your eclipse (If you are using so) or you can just compile and run like,
Compile
javac --module-path /path/to/java-fx-libs/ --add-modules javafx.controls,javafx.fxml *.java
Run
java --module-path /path/to/java-fx-libs/ --add-modules javafx.controls,javafx.fxml MyMainClass

I believe that my example will help someone. I had not succeeded with building REALLY executable jar file, that can be run by click from any place/directory with Java 8. Moving to Java 11 and few other twicks did the business.
Move to Java 11. Specify SDK, other staff in IDE, add this to pom.xml
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>

Using java 8 shouldn't give this problem but it did for me
I created my jar initially from Eclipse Export -> Runnable Jar and it was fine. When I moved to Maven it failed with the above.
Comparing the two jars showed that nothing fx related was packaged with the jar (as I'd expect) but that the Eclipse generated manifest had Class-Path: . in it. Getting maven to package the jar with the following worked for me (with Java 8)
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>com.pg.fxapplication.Main</mainClass>

I know it may not be the "proper" way of launching an javafx application but i have struggled with this problem for some time and came up with a workaround that does not require to use any external packaging applications, force you to use ant or maven plugin (which conflicts with the shade plugin) etc...
The solution uses Utils4j to load jfxrt dynamically at runtime. You cannot load it in a class extending javafx.application.Application, do it in a separate class and name it for example: Launcher
import org.fuin.utils4j.Utils4J
public class Launcher {
public static void main(String[] args) {
Utils4J.addToClasspath("file:///"+System.getProperty("java.home")+ File.separator+"lib"+File.separator+"jfxrt.jar");
// CODE TO RUN YOUR CLASS THAT EXTENDS javafx.application.Application goes here.
}
}
you can include Utils4j with your project (if using maven):
<dependency>
<groupId>org.fuin</groupId>
<artifactId>utils4j</artifactId>
<version>0.7.0</version>
</dependency>

I use maven and I just run this mvn install:install-file -Dfile="/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre/lib/jfxrt.jar" -DgroupId=com.oracle.javafx -DartifactId=javafx -Dversion=2.2 -Dpackaging=jar in terminal(Maybe a little difference in Windows.). Then maven will install jfxrt.jar then you can simply reference it as
<dependency>
<groupId>com.oracle.javafx</groupId>
<artifactId>javafx</artifactId>
<version>2.2</version>
</dependency>

If you are using netbeans like me and you have two versions of JDK installed, then you should change the classpath to the appropriate java installation in the config file. This is also a bug in Netbeans:
There are two ways to do it:
Either start NetBeans with --jdkhome by executing this:
"C:\Program Files\NetBeans Dev 201402160001\bin\netbeans.exe" --jdkhome "C:\Program Files\Java\jdk1.7.0_51"
Or set the "netbeans_jdkhome" property in /etc/netbeans.conf e.g.
# Default location of JDK, can be overridden by using --jdkhome <dir>:
netbeans_jdkhome="C:\Program Files\Java\jdk1.7.0_51"

IntelliJ and maybe other IDE's do not refactor your Run/Debug configuration. You must manually change your package name preceding the name of your Main class. For instance, change 'sample.Main' to 'com.company.package.ui.Main' so it will launch correctly next time you try to run it. The IDE might have already marked the Run/Debug button with a red cross because it couldn't find the main class. It also gives a warning when you open the Run/Debug configuration.

I already answered it on "Ask ubntu".
I recommend you to go with https://openjfx.io/openjfx-docs/ .i am using Eclipse IDE but it works for all IDE
Then you can refer to this global variable when setting the VM options as:
In IDE Right-click on project->Run As -> Run Configuration ->Arguments->VM Arguments
For Windows,
--module-path "\path to javafx\lib" --add-modules javafx.controls,javafx.fxml
For Linux,
--module-path /path to javafx/lib --add-modules javafx.controls,javafx.fxml

I'm developing on Linux a simple WebApp i got the same error, but is really easy to fix it (assuming you are developing on the command line as myself).
cat compile.sh
#!/bin/bash
/usr/lib/jvm/jdk1.7.0_25/bin/javac WebViewSample.java -cp /usr/lib/jvm/jdk1.7.0_25
/jre/lib/jfxrt.jar
$ cat run.sh
#!/bin/sh
JAVA_HOME=/usr/lib/jvm/jdk1.7.0_25/bin/
CLASSPATH=/usr/lib/jvm/jre1.7.0_25/lib/jfxrt.jar:.
$JAVA_HOME/java -cp $CLASSPATH WebViewSample $* 2>&1 /dev/null | awk -F\| '{ print $2"|"$3 ; exit $1 }'
exit $?

I had a problem of not finding the Pair class from javafx.
It seems that vanilla eclipse (without the e(fx)clipse extension) doesn't search the javaFX runtime jar included with java.
I just added to my eclipse project build path this external jar (or if you are in a debug configuration, add the external jar in the JRE tab of the debug configuration):
$JAVA_HOME/jre/lib/ext/jfxrt.jar
(replace JAVA_HOME with your jdk folder)
For me it was in /installs/jdk1.8.0_211/jre/lib/ext/jfxrt.jar

in eclipse environment: add jfxrt.jar to Bundle-ClassPath in MANIFEST.MF file.
Bundle-ClassPath: .,
jfxrt.jar
