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:
➢ Open JDK (for which you also need IcedTea WebStart plugin) ➢ For more info check these out: Simpler & +Complete
Installation for Windows
Just download Java SE Runtime Environment 6u45 and install it according to Oracle instructions.
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
