How to start JavaFX 11 application outside IDE? 核能气质少年 2020-07-07 06:50:08

问题

I downloaded:
- OpenJDK 11.0.2
- JavaFX SDK 11.0.2
Both files are extracted to path C:/Program Files/Java/

OS: Windows 10
IDE: NetBeans 10.0

Paths:

JAVA_HOME = C:/Program Files/Java/jdk-11.0.2  
PATH_TO_FX = C:/Program Files/Java/javafx-sdk-11.0.2/lib

Inside Path system variable add %JAVA_HOME%/bin

In NetBeans I created Java Application project named JFXDev which contains one package com. Inside com package is one main class with following code:

package com;

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 Main extends Application {

        @Override
        public void start(Stage primaryStage) {
            Button btn = new Button();
            btn.setText("Say 'Hello World'");
            btn.setOnAction(new EventHandler<ActionEvent>() {

                @Override
                public void handle(ActionEvent event) {
                    System.out.println("Hello World!");
                }
            });

            StackPane root = new StackPane();
            root.getChildren().add(btn);

            Scene scene = new Scene(root, 300, 250);

            primaryStage.setTitle("Hello World!");
            primaryStage.setScene(scene);
            primaryStage.show();
        }

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

}

Properties of projects are modified:
1) Libraries -> Modulepath added path C:/Program Files/Java/javafx-sdk-11.0.2/lib
2) Libraries -> Classpath added path C:/Program Files/Java/javafx-sdk-11.0.2/lib/javafx.controls.jar
3) Run -> VM Options: added --add-modules=javafx.controls,javafx.fxml

When I start application with NetBeans it works perfectly but I was unable to start application from dist folder. I tried following commands in cmd:

Command: java -jar JFXDev.jar
- Response: Error: could not find or load main class com.Main
Command: java --module-path '%PATH_TO_FX% --add-modules=javafx.comntrols JFXDev
- Response: Error: Could not find or load main class Files/Java/javafx-sdk-11.0.2/lib
Command: java --module-path %PATH_TO_FX% --add-modules=javafx.comntrols Main
- Response: Error: Could not find or load main class Files/Java/javafx-sdk-11.0.2/lib
Command: java --module-path %PATH_TO_FX% --add-modules=javafx.comntrols com.Main
- Response: Error: Could not find or load main class Files/Java/javafx-sdk-11.0.2/lib
Command: java --module-path "C:/Program Files/Java/javafx-sdk-11.0.2/lib/" --add-modules=javafx.comntrols com.Main
- Response: Error: Could not find or load main class Main

Later I added module-info.java file:

module JFXDev {  
    requires javafx.controls;  
    exports com;  
}

But it doesn't make any difference.
What I'm doing wrong, any advice or suggestion?

I tried steps from https://openjfx.io/openjfx-docs/#install-javafx but I get same error :/

回答1:

"Actual" Answer

Some of those errors you've provided indicate a problem with spaces in your arguments (e.g. C:/Program Files/...). Surround %PATH_TO_FX% with quotes: "%PATH_TO_FX%". Then, as you said in a comment, the correct command line for you is:

java -p "%PATH_TO_FX%" --add-modules javafx.controls -jar <path-to-jar-file>

Rest of Answer

From the information you've provided, it's difficult (for me at least) to tell what exactly the problem is. Instead, I'll give some examples of launching a JavaFX application from the command line, both modular and non-modular.

Let's say you have a project with one class—the main class—named com.example.Main. This class extends Application and displays a simple window. Let's also say that, when the code is modular, the module looks like:

module app {
    requires javafx.controls;
    exports com.example to javafx.graphics;
}

And your project structure looks like this:

\---<project-directory>
    +---out
    |   +---artifacts
    |   |       app-1.0.jar (modular or non-modular)
    |   |
    |   \---classes
    |       |   module-info.class (when modular)
    |       |
    |       \---com
    |           \---example
    |                   Main.class
    |
    \---src
        |   module-info.java (when modular)
        |
        \---com
            \---example
                    Main.java

Then your command line will look like one of the following (Windows oriented):

Non-modular

Exploded Directory

java -p "%PATH_TO_FX%" --add-modules javafx.controls -cp out\classes com.example.Main

Jar File

java -p "%PATH_TO_FX%" --add-modules javafx.controls -jar out\artifacts\app-1.0.jar

Note: Requires Main-Class attribute in the manifest.

Modular

Exploded Directory

java -p "%PATH_TO_FX%;out\classes" -m app/com.example.Main

Jar File

java -p "%PATH_TO_FX%;out\artifacts" -m app/com.example.Main

Or if the Jar was created/updated with --main-class

java -p "%PATH_TO_FX%;out\artifacts" -m app

Notes:

The above assumes that <project-directory> is the working directory.
-p is shorthand for --module-path
-m is shorthand for --module
-cp is shorthand for --class-path or -classpath

NetBeans 10 JUnit Jar not found

NetBeans 10 JUnit Jar not found 早过忘川 2020-06-14 04:35:23

问题

I have a new installation of NetBeans 10. Trying to run some initial unit tests I just created, I get the following error:

The <classpath> or <modulepath> for <junit> must include junit.jar if not in Ant's own classpath

I could probably hack the build script to include junit.jar, but I want to know: what's the right way to fix this?

Shouldn't NetBeans come with a version of JUnit already accessible? Should I configure my project differently? How do I add a path to the library?

How can I find the classpath for Ant (and what version/binary NetBeans is using)?

The project Test Libraries shows that JUnit 5.3.1 is present, I have three Jar files listed there: junit-jipiter-api, junit-jupiter-params, junit-jupiter-engine. But it seems to be not actually found.

The project is a standard Java Library (no main class). I didn't add any "extras" or mess with the default project setup that NetBeans uses. Just used the basic setup wizard thing.

Re. a reply from the NetBeans mailing list by Geertjan Wielenga, he pointed me at this thread and reply:

Yep...

We never got around to implementing JUnit 5 support for Ant based projects in NB 10.

So I think it's just not going to work. I'll try the suggested reversion to JUnit 4 below.

回答1:

I'm running netbeans 10 as well, in xubuntu if that helps. I have no idea what is going on, so I had to revert to junit4. EDIT: To be perfectly clear, ant needs junit.jar which is nowhere to be found in the default netbeans 10 installation. Until someone brings a better solution, revert to junit4:

1) in your test libraries, right click and import the junit 4.1.2 ones.

2) remove the junit 5.3 ones.

3) scrap all the imports in your test file and use the junit4 ones. ie your imports will look like:

import static junit.framework.Assert.assertEquals;
import org.junit.Test;
import org.junit.*;
/*import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;*/

4) scrap the beforeAll and other test tags. Only leave the @Test one.

5) save all, close and re-open the project. It will complain that the hamcrest libraries for junit4 are not imported. Allow netbeans to fix it for you.

With that done, I was able to test successful and failing tests. I guess when you generate the junit tests with the template generator, it will generate the junit5 ones, so, a bit annoying. But you'll have tests!

i am new to java fx and i have downloaded Apache Netbeans 9 which runs on java 11.

since java fx is shipped separately, i have downloaded openjfx-11.0.1_SDK and followed steps in this link https://openjfx.io/openjfx-docs/#install-javafx

when i try to create java fx application in apache netbeans , i am getting below error

Failed to automatically set-up a JavaFX Platform. Please go to Platform Manager, create a non-default Java SE platform, then go to the JavaFX tab, enable JavaFX and fill in the paths to valid JavaFX SDK and JavaFX Runtime. Note: JavaFX SDK can be downloaded from JavaFX website

attaching screen shot of netbeans 10.

回答1:

Setting up the correct Environment For creating JavaFX11 application in Apache Netbeans 10 is Quite A Hustle .... This Link Might Help You in some extent

But even after completing these steps you will find even more Errors while running the project... Here is the Possible solution for that scenario

回答2:

I had the same issue on Netbeans 11. I solved this issue by following below steps.

Download the javafx.zip file from the website and after downloading it put it on JDK folder.
First, click on Manage Platforms and then click on Add platform and after clicking on Add platform it will ask of the filename, so give the path till JDK folder.
After giving path click on next and it will ask for platform name and platform sources so in platform sources give the path till src.zip (jdk/lib/src.zip) and press finish button.
After finishing button, you will see the new platform is added with the same name you have given platform name then click on it and go-to sources and click on Add Jar/Folder button and give the path till javafx.zip file which is saved on JDK folder.
After giving path click on add Jar/folder and close it. After closing it click on JavaFX platform and in that you will see the platform name is there click on it and create the project.

How to create Web Application in Apache Netbeans 10?

How to create Web Application in Apache Netbeans 10? 荒凉一梦 2020-01-01 10:48:26

问题

Just I've downloaded Netbeans 10. While creating new project, I'm not getting option 'Web Application'.

How to do it? Is there GUI design builder for web applications in Apache Netbeans 10?

回答1:

Unlike some earlier NetBeans releases such as 8.2, Apache NetBeans 10.0 does not support web development by default, and that is why you do not see an option for Java Web under the Categories listed within the Project Wizard. See What's Happened to My Favorite NetBeans Plugins? for additional background information.

However, web development can still be performed using Apache NetBeans 10.0. You just need to install some plugins first:

Go to Tools > Plugins and select the Available Plugins tab.
Ensure that the entries are sorted in ascending Category order. Click the Category column header to do that if necessary.
Scroll down and locate the entries for the Category named Java Web and EE.
Under the Install column check all of those entries:
Click the Install button to install those checked Java Web and EE plugins.
Follow the instruction for the Installer wizard. The requested plugins will be downloaded and installed, and you will be invited to click Finish to restart NetBeans.
After the restart select File > New Project.... There should be new entries in the Categories list named Java Web and Java EE, allowing you to create web and EE applications:

Troubleshooting:

If there are no entries for Java Web and EE on the Available Plugins tab then update your question with a screen shot of Tools > Plugins > Settings.
If the plugins appear to install correctly but Java Web and Java EE are still not available under the Project Wizard after a restart then update your question with:
- A screen shot of Tools > Plugins > Installed, with the User Installed Plugins entry selected.
- The recent content of the NetBeans log (View > IDE Log).

回答2:

If you're not seeing the Java Web and EE categories, you need to go into Settings and make sure Netbeans 8.2 Plugin Portal is checked like in the image below.

Apache Netbeans 10 CVS plugin not available?

旧街凉风 — Wed, 11 Dec 2019 09:19:32 +0000

Apache Netbeans 10 CVS plugin not available? 旧街凉风 2019-12-11 17:19:32

问题

i finally upgraded to Apache Netbeans 10 (from 8.2) and wanted to install the CVS plugin as usual using the menus Tools->Plugins->Available Plugins

However, i cannot seem to find/access the plugin. In Settings i activated the Netbeans 8.2 Plugin Portal, however i still have (after updating) only 31 Available Plugins and 9 Installed.

When i try to open a CVS versioned project, netbeans recognizes this and tries to automatically get CVS - but the download fails.

So, how can i install the CVS Plugin in Apache Netbeans 10?

回答1:

Select Tools > Plugins > Settings
Add the Update Center which includes the CVS plugin to the Configuration of Update Centers list:
- Click the Add button to open the Update Customizer Center dialog.
- In the Name field enter some descriptive value (e.g. Latest Development Build), and in the URL field enter this URL: http://bits.netbeans.org/dev/nbms-and-javadoc/lastSuccessfulBuild/artifact/nbbuild/nbms/updates.xml.gz
- Click OK to close the Update Customizer Center dialog, and return to the Settings tab.
For that new entry named Latest Development Build, check its Active checkbox:
Select Tools > Plugins > Available Plugins
Enter CVS in the search field and the CVS plugin should be listed:
Check the Install checkbox for the CVS plugin, click the Install button and follow the wizard's instructions.

After that you should be able to use CVS without needing to restart NetBeans:

Select Tools > Options > Team > Versioning to configure CVS.
Select a project in the Projects panel, right click and select Versioning > Import into CVS Repository to import a project into CVS.

Ubuntu 18.04/Netbeans 10.0 Fatal Error: Unable to find package java.lang in classpath or bootclasspath

Ubuntu 18.04/Netbeans 10.0 Fatal Error: Unable to find package java.lang in classpath or bootclasspath 戏子无情 2019-12-11 15:26:22

问题

First, I work on Ubuntu 18.04 with netbeans 10.0 and open JDK 11. When I create a basic new project, alerts directly triggered.

cannot access java.lang
Fatal Error: Unable to find package java.lang in classpath or 
bootclasspath

I tried to uninstall/install netbeans and openJKD 11 but nothing work.

I looked on lots of forums discussions with this kind of problem but nothing work. For information,

xxx:~$java -version

gives

openjdk version "11.0.3" 2019-04-16
OpenJDK Runtime Environment (build 11.0.3+7-Ubuntu-1ubuntu218.04.1)
OpenJDK 64-Bit Server VM (build 11.0.3+7-Ubuntu-1ubuntu218.04.1, mixed mode, sharing)

i don't know what i'm missing, if someone can help me...

回答1:

You have NetBeans 10 version, but your JDK is version 11. So try use NetBeans 11 version... or download/install JDK 10 (the same as NetBeans).

回答2:

Configure the platform, it seems that installers for Ubuntu 18.04 missed the path to Java platform JDK11.

Add a new definition pointing to the right folders.

Platform Name: JDK 11 Platform Folder: /usr/lib/jvm/default-java

Then check the Sources/Source/Binary Format that must be configured to 11.
