Created page with "When installing Java you can install: ➔ JRE ➢ Java Runtime Environment ➢ Install if all you’re gonna do is run Java applications ➢ The JRE consists of the Java Vi..."

New page

When installing Java you can install:
➔ JRE
➢ Java Runtime Environment
➢ Install if all you’re gonna do is run Java applications
➢ The JRE consists of the Java Virtual Machine (JVM): Java platform core classes, and supporting Java platform libraries on top of which Java applications will run.

➔ JDK
➢ Java Development Kit
➢ Also includes the JRE
➢ Install if you’re developing java in your PC, it’s got all tools for development namely compiling projects
➢ Needed when working with Eclipse / Ant / Maven / NetBeans ...

➔ If you’re working with e-lab on your computer then make sure you install the JDK
➢ Preferably use Java 6_45

➔ Oracle’s JDK is recommended but you may also choose another JDK, like:
➢ [http://openjdk.java.net/, Open JDK] (for which you also need [http://openjdk.java.net/projects/icedtea/, IcedTea WebStart plugin])
➢ For more info check these out: [http://stackoverflow.com/questions/1977238/why-should-i-use-the-oracle-jdk-over-the-openjdk-or-vice-versa, Simpler] & [http://www.infoq.com/news/2009/01/jdk-openjdk-icedtea, +Complete]

==Installation for Linux==
➔ Download the binnary: *.bin
➔ Go to the java installation directory
➢ Something like “/usr/lib/jvm/oracle-jdk”
➢ This must coincide with JAVA_HOME variable value for the path
➔ Commands to install (example):
$ chmod a+x jre-6u30-linux-x64.bin
(Now we got it to be executable! lets install it!)
$ ./jre-6u30-linux-x64.bin
export JAVA_HOME="/usr/lib/jvm/oracle-jdk"
export PATH="$PATH:$JAVA_HOME/jre/bin:$JAVA_HOME/bin
