Create Java web applications easily
The integrated development environment Eclipse is a powerful tool for computer programming. It features the base workshop as well as extensive plugin support, letting you customize the environment to your tastes.
- Indeed, when you create a new Servlet in Eclipse, the only option is to use the Java EE, javax libraries. Attempts to change to Jakarta libraries will cause errors. One trick is to switch your target runtime to a new server that has the Jakarta EE libraries such as the latest Tomcat version (currently 10).
- So the following were my criteria for a cloud IDE: An intuitive UI that resembles eclipse Is designed for Java and Java EE development Connects to cloud based services such as Amazon Web Services and Git Hub.
- In order to accelerate business application development for a cloud-native world, leading software vendors collaborated to move Java EE technologies to the Eclipse Foundation where they will evolve under the Jakarta EE brand.
Get to coding!
Work anywhere thanks to Eclipse’s cloud-based feature that shares your projects to the cloud.
Eclipse is open source and free, which means that you get frequent updates, many versions with unique features to choose from and a wide variety of plugins. This also means you’re fully capable of taking Eclipse’s code and developing an IDE that suits your personal needs, all while coding within Eclipse itself.
Projects created within Eclipse are easy to maintain and keep secure. However, if you are sharing your computer, other users may be able to access your projects.
Eclipse is great if you’re trying to learn a new programming language, especially if you already know one as you won’t need to install a secondary IDE for that language. To find the new plugin you need for the next language you’re learning, simply use Eclipse’s marketplace. The marketplace has thousands of plugins and tools that are ready to be installed.
Where can you run this program?
Eclipse can be installed on Windows computers, Mac Cocoa, and Linux systems. This gives you full cross-platform use thanks to the cloud feature of Eclipse.
Is there a better alternative?
No, there are many IDE programs out there such as WebStorm IDE, but no IDE truly has as many plugins available and supports as many languages as Eclipse.
Eclipse is a robust development environment with thousands of plugins supported. The vast selection gives you multiple languages to choose from and other handy add-ons.
Should you download it?
Yes, if you’re a developer or if you’re looking to code, then this is a must-have tool. It contains an extensive collection of plugins and supports many programming languages.
- Powerful code editor
- Great user interface
- Large community
- Long initialization process
- No encryption
- Version control is sometimes buggy

1. Download and Install EclipseEclipse IDE is available on major operating systems: Windows, Mac OS X and Linux. It supports both 32 and 64-bit CPU architecture. Eclipse IDE is a Java-based application so it requires JDK/JRE installed first.You can download and install Eclipse in one of two ways: using an installer or download a ZIP package.Download and Install Eclipse IDE using Eclipse Installer:In this way, you download a small program called Eclipse Installer. Run this program and choose a package you want to install:
2. WorkbenchA window instance of the IDE is referred to as the Workbench. A workbench window consists of one or more Perspectives. And a perspective contains Editors and Views.You can open multiple workbench windows simultaneously (via menu Window > New Window). For example, when you are working on two projects - you can open two workbenches - each for one project. But all workbenches are used for only one Workspace.
3. WorkspaceWorkspace is a directory on your computer - where the projects are stored. You must choose a workspace when starting Eclipse:There can be one or more projects in a workspace - which means you can work with multiple projects simultaneously. However, you can work in one only workspace in a working session of Eclipse. And to switch to another workspace, click File > Switch Workspace from the main menu.Eclipse stores preferences separately for each workspace in the .metadatadirectory in the workspace’s root. That means each workspace has its own settings for layouts, JDKs, servers, etc.So you use a workspace to group related projects that share common settings. For example, you can create a workspace (create a directory) for developing an application that consists of several projects; a workspace for Swing projects; a workspace for Java EE projects; a workspace for Spring projects, and so on.The following screenshot shows multiple projects listed in the current workspace:
4. PerspectivesIn Eclipse, a perspective provides initial layout that is organized to help programmers accomplish a task or work. Each perspective contains a different set of editors and views. For example, the Java perspective contains the following editors and views:
- Java Editors: for editing Java source files.
- Package Explorer: allows you to navigate the projects.
- Outline: displays the structure of source file in the active editor.
- Problems: shows errors, warnings and problems detected.
- Javadoc: allows you to preview Javadoc of a class, method, field…
- Declaration: shows declaration statement for the variable at the cursor position.
- Task List: displays tasks downloaded from a popular bug tracker tool like Bugzilla, Mantis…The following screenshot is of a Java perspective:When you are working in the perspective, you and open more editors and views when needed, but initially a perspective contains a fixed set of editors and views. The toolbars and menu items are also changed according to the purpose of the current active perspective.And this is the Debug perspective that allows you to debug a running program:By default, Eclipse provides several perspectives, as shown below:You can see this list when opening a perspective from the menu Window > Perspective > Open Perspective > Other…
Eclipse Ide Ee DeveloperFor Java development, you use only few perspectives most of the time, e.g. Java, Java EE and Debug. If you use version control, then you will frequently switch to Git or Team Synchronizing perspectives.In Eclipse, you can switch among opened perspectives by clicking on the perspective icons in the toolbar or by pressing the shortcut Ctrl + F8. You can open perspectives in the same workbench window (default) or in new windows.Note that different perspectives can have different views but they all share the same editors.You can customize a perspective, e.g. arrange views and editors in the way you like, and save it as your own perspective.To reset the active perspective to its default layout, click Window > Perspective > Reset Perspective…
5. EditorsAn editor allows you to edit a source file. For example, when you double-click a .javafile in the Project Explorer/Package Explorer view, a Java editor is opened in the editor area which is usually at the center of the workbench:Notice the gray border at the left margin of the editor area may show small icons to indicate errors, warnings, problems and information at the corresponding line.Each type of find can be opened with the associated editor. If Eclipse doesn’t have associated editor for a file type, it will try to open using an external program available in the operating system.There can be multiple editors opened and they are stacked in the editor area, but only one editor is active at a time. The name of the file is displayed in the title bar of the editor, and the asterisk (*) indicates that the editor has unsaved changes.In Eclipse, you can use the shortcut Ctrl + F6 to switch among editors.
6. ViewsA view allows you to navigate the information in the workbench. For example, in the Project Explorer view, you can navigate the structure of projects in a workspace:A view also provides alternative representation to support an editor. For example, the Outline view displays structural elements of the source file in the active editor. So if you are editing a .javafile, it displays the classes, fields and methods of that file:Using the Outline view, you can quickly jump to an element in the source file.You can resize, move, minimize and maximize views in a perspective. A view can be detached from the workbench and becomes a floating window (right-click on a view’s title bar and click Detach).A view has a pull-down menu that offers actions allowing you to customize the representation of the view. You can access this menu by clicking on the down arrow at the top right corner of the view. For example, the following screenshot shows the pull-down menu of the Project Explorer view:To open a view in Eclipse, click Window > Show View. And to switch among opened views, press Ctrl + F7.
7. ToolbarsThe last visual component I want to tell you in Eclipse is the toolbars. There are 4 kinds of toolbars in Eclipse:- Main toolbar: appears below the main menu, the main toolbar consists of buttons that are grouped into different sections: Open/create/save project, Run, Debug, Navigation, Search…The buttons vary depending on the current perspective.
a- Individual view toolbar: a view can have its own toolbar in its title bar area or at the top-right corner. For example, you can see the toolbar of the Servers view in this screenshot:- Perspective switcher toolbar
Download Eclipse Ee: this toolbar contains buttons that allow you to switch among opened perspectives in the workbench. You can see this toolbar at the right side of the main toolbar:It also contains a button (the left most one) that allows you to open the list of all perspectives.- View stack toolbar: this is a special toolbar which appears when you minimize a view in a view stack. The icons on this toolbar allow you to open an individual view in the stack. For example, here’s the toolbar appears when the Console
