Re: PSAL failed to Launch Java Applet MacOS Catalina 10.15.4 Same issue starts on MacOS 10.15.x after upgrading Pulse console to 9.1.R7 or 9.1.R8. I want to create an application where a web server can get the MAC Address of the clients logging in. The only possible way I could think of was to create a JAVA applet which contains java.net methods to find the mac address. I am using javascript to call the applet methods, but the browser is not allowing those methods to execute.

Overview

VS Code provides essential language features such as code completion, refactoring, linting, formatting, and code snippets along with convenient debugging and unit test support. VS Code also integrates with tooling and frameworks such as Maven, Tomcat, Jetty, and Spring Boot. Leveraging the power of Visual Studio Code, Java developers get an excellent tool for both quick code editing and also the full debugging and testing cycle. It's a great choice for your Java work if you're looking for a tool which:

Is fast, lightweight, free, and open source.
Supports many other languages, not just Java.
Helps start your Java journey without installing and learning a complex IDE.
Provides great microservices support including popular frameworks, container tooling, and cloud integration.
Offers team-based collaboration features such as Visual Studio Live Share.
Improves your productivity through IntelliSense and other code-aware editing features.

Install Visual Studio Code for Java

VS Code is a fast editor and ships with great editing features. Before you begin, you must have the Java SE Development Kit (JDK) on your local environment. To run VS Code for Java, Java SE 11 or above version is required; for projects, VS Code for Java supports projects with version 1.5 or above. For more details, refer to Configure JDK.

To help you set up quickly, you can install the Coding Pack for Java, which includes VS Code, the Java Development Kit (JDK), and essential Java extensions. The Coding Pack can be used as a clean installation, or to update or repair an existing development environment.

Install the Coding Pack for Java - macOS

Note: The Coding Pack for Java is only available for Windows and macOS. For other operating systems, you will need to manually install a JDK, VS Code, and Java extensions.

Alternatively, you can also add Java language support to VS Code by installing the popular Java extensions by yourself.

Download VS Code - If you haven't downloaded VS Code yet, quickly install for your platform (Windows, macOS, Linux).

Java Applet For Mac Installer

To help set up Java on VS Code, there is a Java Extension Pack, which contains the most popular extensions for most Java developers:

There are also other popular Java extensions you can pick for your own needs, including:

Thanks to the great Java community around VS Code, the list doesn't end there. You can search for more Java extensions easily within VS Code:

Go to the Extensions view (⇧⌘X (Windows, Linux Ctrl+Shift+X)).
Filter the extensions list by typing 'java'.

This document describes some of the key features included in those Java extensions.

Getting started

NOTE: If you are using VS Code on Windows and want to take advantage of the Windows Subsystem for Linux, see Developing in WSL.

For developers new to Java or new to VS Code, we provide a Getting Started experience. Once you've installed the Java Extension Pack, you can open the Getting Started experience from within VS Code with the Java: Getting Started command from the Command Palette. Open the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)) and type 'Java: Getting Started'.

Working with Java source files

You can use VS Code to read, write, run, and debug Java source file(s) without creating a project. VS Code for Java supports two modes, lightweight and standard. Lightweight mode is ideal for scenarios that only deal with source file(s). If you want to work with a full scale project, standard mode will be required. You can easily switch from lightweight mode to standard mode, when needed. To learn more, see Lightweight Mode.

Working with Java project

There are three things you must understand to work with Java in VS Code:

How does VS Code handle Workspaces?
How does VS Code handle Java?
How does VS Code handle Workspaces that contain Java?

VS Code Workspaces

In Visual Studio Code, a 'Workspace' means a collection of one or more filesystem folders (and their children) and all of the VS Code configurations that take effect when that 'Workspace' is open in VS Code. There are two kinds of 'Workspaces' in VS Code, 'folder workspaces' and 'multi-root workspaces'.

A 'folder workspace' is presented by VS Code when you open a filesystem folder (directory) in VS Code.

A 'multi-root workspace' can refer to multiple folders (directories) from disparate parts of the file system and VS Code displays the contents of the folder(s) of the workspace together in the File Explorer. To learn more, see Multi-root Workspaces.

Java project in VS Code

In contrast to IDEs such as IntelliJ IDEA, NetBeans, or Eclipse, the concept of a 'Java project' is provided entirely by extensions, and is not a core concept in the base VS Code. When working with 'Java projects' in VS Code, you must have the necessary extensions installed to work with those project files.

For example, Maven, Eclipse, and Gradle Java projects are supported through Language Support for Java(TM) by Red Hat, by utilizing M2Eclipse, which provides Maven support, and Buildship, which provides Gradle support through the Eclipse JDT Language Server.

With Maven for Java, you can generate projects from Maven Archetypes, browse through all the Maven projects within your workspace, and execute Maven goals easily from an embedded explorer. Projects can also be created and managed with the Project Manager for Java extension.

Visual Studio Code also supports working with standalone Java files outside of a Java project, described in the Java Tutorial with VS Code.

VS Code Workspaces that contain Java project

Assuming the necessary Java extensions are installed, opening a VS Code workspace that contains Java artifacts will cause those extensions to understand those artifacts and present options for working with them.

More details about Java project support can be found in Java Project Management in Visual Studio Code and Build Tools.

Editing

Code Navigation

Java in Visual Studio Code also supports source code navigation features such as search for symbol, Peek Definition, and Go to Definition. The Spring Boot Tools extension provides enhanced navigation and code completion support for Spring Boot projects.

One of the key advantages of VS Code is speed. When you open your Java source file or folder, within a few seconds, with the help of Lightweight Mode, you will be able to navigate your code base with Outline view as well as commands such as Go to Definition and Go to Reference. This is especially useful when you open a project for the first time.

Code Completion

IntelliSense is a general term for language features, including intelligent code completion (in-context method and variable suggestions) across all your files and for built-in and third-party modules. VS Code supports code completion and IntelliSense for Java through Language Support for Java(TM) by Red Hat. It also provides AI-assisted IntelliSense called IntelliCode by putting what you're most likely to use at the top of your completion list.

See also in Java Code Navigation and Editing. VS Code also supports a range of Refactoring and Linting features.

Debugging

Debugger for Java is a lightweight Java Debugger based on Java Debug Server. It works with Language Support for Java by Red Hat to allow users to debug Java code within Visual Studio Code.

Starting a debugging session is easy, click on the Run|Debug button available at the CodeLens of your main() function, or press F5. The debugger will automatically generate the proper configuration for you.

Although it's lightweight, the Java debugger supports advanced features such as expression evaluation, conditional breakpoints, and hot code replacement. For more debugging related information, visit Java Debugging.

Testing

With the support from the Java Test Runner extension, you can easily run, debug, and manage your JUnit and TestNG test cases.

For more about testing, read Testing Java.

Spring Boot, Tomcat, and Jetty

To further improve your Java productivity in VS Code, there are extensions for most popular frameworks and tools such as Spring Boot, Tomcat, and Jetty created by the community.

The Tomcat extension includes an explorer to easily navigate and manage your Tomcat servers. You can create, start, debug, stop, and rename your Tomcat server with the extension.

See Application Servers to learn more about support for Tomcat and Jetty as well as other application servers with VS Code.

Spring Boot support is provided by Pivotal. There are also Spring Initializr Java Support and Spring Boot Dashboard extensions available from Microsoft to further improve your experience with Spring Boot in Visual Studio Code.

See Spring Boot with VS Code to learn more about Spring Boot support with VS Code.

This article is about the support of Java on browsers.

Java Applet Download

Why we need the support of Java on a browser?

If you learned or have some knowledge or have worked in Java then it is likely that you must have come across this concept of Java Applet. So, an Applet is nothing but a Java program but the only difference is that it cannot directly run on a standalone machine. It needs a web browser to run. It is easily embedded within an HTML page and is a client-side concept i.e. runs on client-side.

So, to run Applet, we need a Java-enabled browser. Browsers come with a Java plugin that allows the execution of an Applet on it. And so, the browsers that come to Java enabled, can run Applet without any hassle.

So, now that we know why we need browser support for Java, let’s start with the list of browsers that support it today.

Browser that supports Java:
Browsers require Java plugin which depends on NPAPI (Netscape Plugin Application Programming Interface). Today, the majority of the well-known browsers have dropped the support for that.

Here are browsers that do not support Java Applet any more:

Google Chrome
Firefox
Safari
Microsoft Edge
Opera

So, as you can see that all these browsers not longer support Applet. Even the newer versions of Oracle’s JDK does not come with the support of the Java browser plugin.

The reason for dropping the support was because of security issues and risks that were found.

But there is Internet Explorer that still has the support for Java Applet. So, today Internet Explorer is the only browser that supports Java Applet.

How to enable Java in Internet Explorer?
Following are the steps to enable Java on Internet Explorer:

Click on the ‘Tools’ icon on the top right corner of the window or press Alt+X, if on windows.
Then for the menu select ‘Internet Options’.
Then in ‘Security’ tab, click on ‘Custom level’.
Now, In the pop-up, scroll down and search for ‘Scripting of Java applet’ and make sure it is enabled and click OK.

Note: There is another way if you still want to run Applet and security is not a concern and if you don’t want to use Internet Explorer, then you download an older version of any browser that did support Java Applet.
