Installing Java EE 7 on Linux. Hi, dear friends. In this video, we will install Java EE 7 and Eclipse Neon 3 development tool on Ubuntu Linux. First, I open a web browser and search for java EE 7 JDK. I am doing a bit scroll. And select the link for downloading Java EE 7 with JDK. It redirects me to the Oracle download page. Here, I am selecting 'Linux 64-bit multi-language package'. I click on 'Check box' to accept the terms and press the button to start the download. Oracle wants me to enter my user info to download. Okay, I entered my login info and the download starts. Now, I'm going to download Eclipse Neon 3 IDE. Simply I write, download Eclipse Neon and search select appropriate option of results. It heads me to
the Eclipse download page. In the first option, I select 'Eclipse IDE for Java EE developers Linux 64-bit'. It starts downloading. It will take a while completing of the download. Okay. Downloading finished. I am going to the location of downloads.
The files are here, I am opening a terminal window. I am listing files here using LS command. If you look carefully, you will see the font color of Java EE 7 file is white. That means this file is not executable. We need to give execute permission for it. To do this, we use C-H-M-O-D command. Okay. I gave execute permission to the file. Now, you can see that the font color of the file has changed. It has become green. Now, I am running it. An installation window opened. Click 'Next'. Leave it typical and click 'Next'. Let the installation directory stay the same, click 'next'. Uncheck 'Install update' toolbox and click 'Next'. Click 'Install'. Click 'Next'. Click 'Next'. The installation completed, click 'Exit'. Now, it's time to extract Eclipse IDE. The file is either compressed or archived by tar command.
First, we unzip it using gunzip command. Okay. I made a mistake. The gunzip doesn't include that flags. I need to use it simply gunzip, like this. Now, I'm going to extract it from tar archive using tar command. Okay. It extracted. Let me copy it to my desktop. You can run it either by double clicking or help of a terminal like this. You can run it like this. Click 'OK', for workspace location. Eclipse opened. Let me change the default JRE. Click 'Window', 'Preferences', type JRE to search, click 'Install JREs'. Here, as you see, the default JRE is 1.8. Now, I will add the JRE of our newly installed JDK 7. Click 'Add', click 'Next', click 'Directory'. I want to remind it the place of JDK 1.7 is under my home, GlassFish directory. So, I select 'Home', 'GlassFish', 'JDK 7', 'JRE' and 'OK', click 'Finish' and check the box near the JDK 7. Click 'OK'. By the way, you can see Eclipse version by using 'Help', 'About Eclipse' menu.
