For example, if you use 7-Zip, you can right-click on the file and choose 7-Zip > Extract Here. This will create a folder named eclipse in the same directory as the zip file.
Installing the package
The next step is to run the package and install it on your system. The package does not require any special installation process or administrator privileges. You just need to double-click on the eclipse.exe file inside the eclipse folder that you extracted from the zip file. This will launch the Eclipse IDE.
The first time you run Eclipse, it will ask you to select a workspace location. A workspace is a folder where Eclipse stores your projects and settings. You can choose any folder that you have access to, or use the default one suggested by Eclipse. You can also check the option to use this as the default workspace and not ask again.
After selecting a workspace location, you will see the Eclipse welcome screen. This screen provides some useful links and tutorials to help you get started with Eclipse. You can close the welcome screen by clicking on the X icon on the top right corner. You will then see the Eclipse workbench, which is the main interface for developing and managing your projects. The workbench consists of several views and editors that you can arrange and customize according to your preferences.
Configuring the package
Before you can create and run Java EE applications in Eclipse, you need to configure some settings and components in the package. In this section, we will show you how to add a Java runtime environment, an application server, and a Java EE project to your Eclipse workbench.
Adding a Java runtime environment
A Java runtime environment (JRE) is a software package that provides the libraries and tools for running Java applications. You need to have a JRE installed on your system and added to Eclipse in order to compile and run Java code. The eclipse-jee-2018-09-win32-x86_64.zip package comes with a built-in JRE, but you can also use other JREs that you have installed on your system.
To add a JRE to Eclipse, follow these steps:
Go to Window > Preferences > Java > Installed JREs.
Click on Add... and select Standard VM.
Click on Directory... and browse to the location of the JRE that you want to add. For example, if you have installed the Java SE Development Kit (JDK) 11 on your system, you can find the JRE under C:\Program Files\Java\jdk-11\jre.
Click on Finish. The JRE will be added to the list of installed JREs.
Select the JRE that you want to use as the default one and click on Apply and Close.
You have now added a JRE to Eclipse. You can check the version of the JRE that you are using by going to Help > About Eclipse IDE > Installation Details > Configuration and looking for the java.home property.
Adding an application server
An application server is a software platform that provides the runtime environment and services for deploying and running Java EE applications. You need to have an application server installed on your system and added to Eclipse in order to create and run Java EE projects. The eclipse-jee-2018-09-win32-x86_64.zip package does not come with any application server, but it supports various servers that you can download and install separately, such as Apache Tomcat, GlassFish, WildFly, WebSphere Liberty, and others.
In this article, we will use Apache Tomcat as an example of an application server. Apache Tomcat is an open source web server and servlet container that implements the Java Servlet, JavaServer Pages, Java Expression Language, and WebSocket technologies. You can download Apache Tomcat from its . The latest stable version at the time of writing this article is 9.0.52.
To add an application server to Eclipse, follow these steps:
Download and unzip Apache Tomcat to a local directory of your choice.
Go to Window > Preferences > Server > Runtime Environments.
Click on Add... and select Apache Tomcat v9.0 from the list of server types.
Click on Next and browse to the location of the Apache Tomcat installation directory.
Click on Finish. The Apache Tomcat server will be added to the list of runtime environments.
Click on Apply and Close.
You have now added an application server to Eclipse. You can check the status of the server by going to Window > Show View > Servers. You can also start, stop, restart, or debug the server from this view.
Creating a Java EE project
A Java EE project is a type of project in Eclipse that contains the source code, configuration files, libraries, and resources for developing a Java EE application. You can create different types of Java EE projects depending on the technologies that you want to use, such as Dynamic Web Project, Enterprise Application Project, EJB Project, etc. In this article, we will create a Dynamic Web Project as an example of a Java EE project. A Dynamic Web Project is a project that contains web components such as servlets, JSPs, filters, listeners, etc., as well as static resources such as HTML pages, images, CSS files, etc.
To create a Java EE project in Eclipse, follow these steps:
Go to File > New Project > Dynamic Web Project.
Enter a name for your project and select a target runtime environment. For example, if you have added Apache Tomcat as your application server, you can select Apache Tomcat v9.0 as your target runtime.
Select a dynamic web module version. This is the version of the Java EE specification that your project will follow. For example, you can select 4.0, which is the latest version at the time of writing this article.
Click on Next and configure the project settings as per your requirements. For example, you can change the context root, the content directory, the web.xml deployment descriptor, etc.
Click on Finish. The Dynamic Web Project will be created and added to your workspace.
You have now created a Java EE project in Eclipse. You can see the project structure and contents in the Project Explorer view. You can also edit, run, debug, or deploy your project from this view.
Common errors and solutions
While developing Java EE applications in Eclipse, you may encounter some errors or warnings that prevent you from compiling or running your code. In this section, we will discuss some of the common errors and solutions that you may face while using Eclipse for Java EE development.
Missing Java EE libraries
One of the common errors that you may see in your Java EE project is the missing Java EE libraries in the project build path. This means that Eclipse cannot find the required libraries for compiling and running your Java EE code. This error usually occurs when you create a Java EE project without selecting a target runtime environment, or when you change the target runtime environment after creating the project.
To fix this error, follow these steps:
Right-click on your project and select Properties > Project Facets.
Check if the Java facet and the Dynamic Web Module facet are selected. If not, select them and click on Apply.
Click on Runtimes tab and check if the target runtime environment is selected. If not, select it and click on Apply and Close.
Right-click on your project and select Maven > Update Project....
Check if the error is resolved. If not, right-click on your project and select Build Path > Configure Build Path....
Click on Libraries tab and check if the Java EE libraries are present. If not, click on Add Library... and select JRE System Library or Server Runtime depending on your target runtime environment.
Click on OK and check if the error is resolved.
You have now fixed the missing Java EE libraries error in your project build path. You should be able to compile and run your Java EE code without any issues.
Maven dependencies warnings
Another common warning that you may see in your Java EE project is the Maven dependencies warnings in the Problems view. This means that Eclipse cannot resolve some of the dependencies that are specified in your pom.xml file. This warning usually occurs when you create a Maven-based Java EE project, or when you add or update some dependencies in your pom.xml file.
To fix this warning, follow these steps:
Right-click on your project and select Maven > Update Project....
Select your project and check the option to Force Update of Snapshots/Releases.
Click on OK and wait for Eclipse to update your project dependencies.
Check if the warning is resolved. If not, right-click on your project and select Maven > Download Sources.
Wait for Eclipse to download the sources of your dependencies.
Check if the warning is resolved.
