There are a number of additional software repositories for Red Hat Enterprise Linux. Enabling additional software repositories Only software repositories that have been enabled for downloading are included in the results. The output will show the package name and the software repository it resides in. You can view or search packages that are available to be installed with yum list available: If java is in your path, determine which version: To tell if java is in your PATH use which:
#Java 1.7.0_71 install#
When you install a JDK, a JRE will also be installed. If you have a JRE installed, you can skip the following steps. The output includes the package name, version information, and the software repository it was installed from. You can narrow the list to show only package names starting with java. You can see the list of installed packages with yum list installed. Your system may have one or more Java Runtime Environments (JRE) installed.

# yum update Determine if any Java packages are already installed If updates are available, yum will list them and ask if it is OK to proceed. Now download and install any available updates by running yum update. See Troubleshooting and FAQ for more information. If you don’t see any enabled repositories, your system might not be registered with Red Hat or might not have a valid subscription. # subscription-manager repos -list-enabled Then use su - to change to the root user ID, and use subscription-managerto verify that you have access to Red Hat Software Repositories.

You will also see how to enable access to additional software repositories for a wider selection of packages.įirst, start a Terminal window from the Application menu. In this step, you will learn how to use the yum package management tool to find out which Java packages are available and to download and install updates for your system. If you encounter difficulties at any point, see Troubleshooting and FAQ. If you don’t have a Red Hat Enterprise Linux subscription, get Red Hat Enterprise Linux Developer Suite after registering at. You will need a Red Hat Enterprise Linux 7 system with a current Red Hat subscription that allows you to download software and updates from Red Hat. The whole tutorial should take less than 10 minutes to complete. You will install a Java Development Kit (JDK), and learn what Java packages are available. In this tutorial, you will see how to get started with Java development on Red Hat Enterprise Linux by creating a simple Hello World application. endor-2:~ garex$ /usr/libexec/java_home -v 1.8 -d64 -exec java -fullversionĮndor-2:~ garex$ /usr/libexec/java_home -v 1.7.Get started developing with Java 8 on Red Hat Enterprise Linux in under 10 minutes.

In my case I installed JRE and JDK.īy using the java_home command in your calling script you can always configure the right version for your application, e.g.

Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)īut remember: you could do that, but do not expect certain software to follow that. Java(TM) SE Runtime Environment (build 1.8.0_45-b14) With the following java_home command you permanently switch over to Java 1.8 64 bit: endor-2:~ garex$ java -fullversionĮndor-2:~ garex$ /usr/libexec/java_home -v 1.8 -d64 Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home Take a closer look at this: endor-2:~ garex$ /usr/libexec/java_home -Vġ.8.0_45, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Homeġ.7.0_71, x86_64: "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home In general, for all shell driven applications there is one environment variable you usually set for this and it's called JAVA_HOME. So when each application comes with its own JDK/JRE, you need to tell in some configuration which one to use. For instance, HP Peregrine Service Center does that.

Oracle and its installers install their JDK/JRE in /Library/Internet Plug-Ins/ugin/Contents/Home for the webbrowser plugin and the full JRE/JDK into /Library/Java/JavaVirtualMachines/.Īnd additionally, software packages can come with their own JDK/JRE package. Therefore, you can have multiple versions installed and use multiple versions in Xcode or other IDE. The Apple packaged JRE/JDK is always installed in /System/Library/Frameworks/amework/Versions/Current, where "Current" is a link pointing to the actual version. In some terms this is misunderstanding, but I hope it gets clearer soon:
