• I was trying to install the Java 7 package off of java.com (50MB). When I went and got the one from Oracle (150MB), that one installed correctly. Still no 'Java Preferences' app though. – aroth Feb 13 '13 at 2:40.

Question or issue on macOS:

Oracle for mac

The Java Deployment on Mac OS X presentation, by Scott Kovatch and Chris Bensen, provided an overview of Oracle Java on the Mac. For more information on installing and using Oracle Java for the Mac, refer to the following documentation: Mac FAQ; JDK 7 Installation for Mac OS X; JRE 7 Installation for Mac OS X; Mac OS X Platform Install FAQ.

I want to use the JRE 1.7 that I downloaded from Oracle website.

So I correctly install the .pkg file, and when I try /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version in the terminal I get this :

But in Eclipse I can’t use anything else than JRE 1.6. When I go in Properties > Java Build Path > Add Library > JRE System Library, I can’t find the 1.7 (there is only option for it : JavaSE-1.7 (unbound) with this issue :

What should I do ? Thanks

How to solve this problem?

Solution no. 1:

The download from java.com which installs in /Library/Internet Plug-Ins is only the JRE, for development you probably want to download the JDK from http://www.oracle.com/technetwork/java/javase/downloads/index.html and install that instead. This will install the JDK at /Library/Java/JavaVirtualMachines/jdk1.7.0_<something>.jdk/Contents/Home which you can then add to Eclipse via Preferences -> Java -> Installed JREs.

Solution no. 2:

Try editing your eclipse.ini file and add the following at the top

Of course the path may be slightly different, looks like I have an older version…

I’m not sure if it will add itself automatically. If not go into

Preferences –> Java –> Installed JREs

Click Add and follow the instructions there to add it

Solution no. 3:

You need to tell Eclipse which JDK/JRE’s you have installed and where they are located.

This is somewhat burried in the Eclipse preferences: In the Window-Menu select “Preferences”. In the Preferences Tree, open the Node “Java” and select “Installed JRE’s”. Then click on the “Add”-Button in the Panel and select “Standard VM”, “Next” and for “JRE Home” click on the “Directory”-Button and select the top level folder of the JDK you want to add.

Its easier than the description may make it look.

Hope this helps!

System Requirements

  • Any Intel-based Mac running Mac OS X 10.7.3 (Lion) or later.
  • Administrator privileges.

Note that installing the JDK on a Mac is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.

Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version.

JDK 7 Installation Instructions

Mac

Installation of the 64-bit JDK on Mac Platforms

When you download the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.

Depending on your processor, the downloaded file has one of the following names:

Oracle java 7 download mac os x 10.11
  • jdk-7u<version>-macosx-amd64.dmg
  • jdk-7u<version>-macosx-x64.dmg

Where <version> is 6 or later.

1. Download the file. Before the file can be downloaded, you must accept the license agreement.

2. From either the Downloads window of the browser, or from the file browser, double click the .dmg file to launch it.

3. A Finder window appears containing an icon of an open box and the name of the .pkg file Double click the package icon to launch the Install app.

4. The Install app displays the Introduction window. Click Continue.

4a. Note that, in some cases, a Destination Select window appears. This is a bug, as there is only one option available. If you see this window, select Install for all users of this computer to enable the continue button. Click Continue.

5. The Installation Type window appears. Click Install.

6. A window appears which says 'Installer is trying to install new software. Type your password to allow this.' Enter the Administrator login and password and click Install Software.

7. The software is installed and a confirmation window appears. Click the ReadMe for more information about the installation.

After the software is installed, delete the dmg file if you want to save disk space.

Determining the Default Version of the JDK

Mac Os Oracle Vm

A: If you have not yet installed Apple's Java Mac OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See Note for Users of Macs that Include Apple Java 6 Plug-in.

There can be multiple JDKs installed on a system – as many as you wish.

When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.

You can determine which version of the JDK is the default by typing java -version in a Terminal window. If the installed version is 7u6, you will see a string that includes the text 1.7.0_06. For example:

To run a different version of Java, either specify the full path, or use the java_home tool:

For more information, see the java_home(1) man page.

Uninstalling the JDK

To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.

Navigate to /Library/Java/JavaVirtualMachines and remove the directory whose name matches the following format:*

For example, to uninstall 7u6:

Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.

*The 7u4 and 7u5 releases were installed into a directory that does not follow this format. To uninstall 7u4 or 7u5, remove the 1.7.0.jdk directory from the same location.
