Java Runtime Environment Editor's Review
Java Runtime Environment is an essential piece of software for pretty much any computer. Often called the Java Virtual Machine, it’s a vital layer of invisible technology that helps you to run a whole gamut of Java web-based applications. It comes as standard with some operating systems, so you may just need to upgrade.
Oracleには、Java Platform Standard Edition (Java SE) 8を実装する製品として、Java SE Development Kit (JDK) 8およびJava SE Runtime Environment (JRE) 8という2つの製品があります。. Java SE Runtime Environment is a freeware java runtime environment software app filed under components and made available by Oracle for Windows. The review for Java SE Runtime Environment has not been completed yet, but it was tested by an editor here on a PC. Java SE Runtime Environment 8 Downloads. Do you want to run Java™ programs, or do you want to develop Java programs? If you want to run Java programs, but not develop them, download the Java Runtime Environment, or JRE™.
Allegedly, there are almost one billion downloads of Java Runtime per year and it’s reputed to be on three billion mobile phones. For most end-users, this software gives them everything they need without them having to think about it.
Programmers and other specialists may find more to gripe about. And there are some questions about Java’s fitness for future app development. Depending on its ability to flex to meet future requirements, some of its competitors may finally get a crack of the whip.
Pro's: World domination. Java Runtime Environment is so easy to use and very reliable that pretty much everyone in the known universe uses it, often without knowing what it is or what it’s doing.
Con's: Microsoft Windows doesn’t come with Java built-in so you will have to get it from a third-party supplier. Just make sure you get the genuine Sun Microsystems version of Java Runtime Environment.
Conclusion: It’s hard to see how anyone could use a computer or smart phone without Java Runtime Environment. It’s the oil on the wheels of the majority of web-based applications and few programmes will run on the internet without it. There are other alternatives out there, but for most end-users, Java Runtime is pretty unbeatable. It’s free, it works and almost everyone in the known universe with a computer or phone has it.

Apache Tomcat is a Servlet/JSP container and version 8.0 implements the Servlet 3.1 and JavaServer Pages 2.3 specifications. Please note that Apache Tomcat 8.0 requires a Java Standard Edition Runtime Environment (JRE) version 7 or later. So we start with installing a recent version of Oracle’s JRE.
Install Oracle JRE 8 on Debian Linux (or Raspbian)
To install Oracle’s Java Runtime with apt-get, we first need to entend the list of apt-get’s sources. Once that is done, an java-installer will actually install the Java SE Runtime Environment. Here are the steps to follow:
As I’m writing this, the newly installed Java Runtime reports its version as 1.8.0_101:
With Java now installed we move on, installing Tomcat. However, it may be beneficial to have an dedicated user for Tomcat.
BTW, Java got installed into this location: /usr/lib/jvm/java-8-oracle
BTW, Java got installed into this location: /usr/lib/jvm/java-8-oracle
.. which should result in something like this:
Installing Tomcat 8.5.x
To make it easy to replace this release with future releases, we are going to create a symbolic link that we are going to use when referring to Tomcat (after removing the old link, you might have from installing a previous version):
Since we created a tomcat user, he should also own all these files in
If Tomcat’s default HTTP port (8080) is already in use, you need to edit the server.xml configuration file, e.g.
edit /usr/share/tomcat/conf/server.xml and replace 8080 with 8000
edit /usr/share/tomcat/conf/server.xml and replace 8080 with 8000
Starting Tomcat

Stopping Tomcat
Staring Tomcat when the server boots
To start Tomcat automatically, every time the server re-boots, save this script in /etc/init.d/tomcat
Now change the permissions of the newly created file and add the correct symlinks automatically:
Tomcat relies heavily relies on the SecureRandom class to provide random values, for instance to generate session ids. During startup, if entropy source that is used to initialize SecureRandom is short of entropy, this can lead to very long delays, which can be confirmed in the logs/catalina.out log file. Adding
JAVA_OPTS='-Djava.security.egd=file:/dev/urandom'
at the beginning of the bin/catalina.sh file, will significatinly speedup the startup time.While not my preferred Linux distribution, RedHat and CentOS are the standard in Corporate America. So here are a few comments on how to install Java and Tomcat on RedHat:
Installing Java 8
This will install Oracle’s Java 8 or more specifically Java(TM) SE Runtime Environment (build 1.8.0_51-b16) and Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode) here: /usr/java/jdk1.8.0_51/
Later, if you decide to run Tomcat on port 80, you will also need to execute this:
and cat this content
Jre Jdk 8u60
into /etc/ld.so.conf.d/java.conf
