How to Compile and Run JavaFX 2.0 Code Using the Command Line in Java 7 and Above?

Compile JavaFX 2.0 Code Using Command Line

Java 8 and Above

Recent versions of JavaFX have seamlessly integrated with the Java runtime classpath. To compile and execute your code, simply run:

javac Fxservidor.java
java Fxservidor

Java 7 and JavaFX 2.x

For Java 7 and JavaFX 2.x, compile your code using the Java Compiler, specifying the JavaFX SDK Runtime Library (jfxrt.jar) in the classpath:

"JDK_HOME\bin\javac" -classpath "JAVAFX_SDK_HOME\rt\lib\jfxrt.jar" fxservidor.java

Executing the Compiled Class

To execute the compiled class, specify the JavaFX Runtime Library in the classpath:

java -classpath "JAVAFX_SDK_HOME\rt\lib\jfxrt.jar;." Fxservidor

Sample Command Line Script

For convenience, consider using a batch script similar to this:

@echo off

if exist .\jfxrt.jar (
  set CLASSPATH=.\jfxrt.jar;.;
) else (
  echo No JavaFX Runtime Library (jfxrt.jar) found.
  exit /B 1
)

javac Fxservidor.java
java -cp "%CLASSPATH%" Fxservidor

Sample Code Modifications

To ensure compatibility, modify your code as follows:

<code class="java">import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class Fxservidor extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) {</code>
