Ubuntu/lubuntu/xubuntu Linux installation Eclipse

One installation JDK

1. Download JDK 7
Choose to download the latest JDK version of JDK 7 from http://www.oracle.com/technetwork/java/javasebusiness/downloads/.

2. Unzip the file
$ sudo MKDIR/USR/LIB/JVM
$ sudo mv jdk-7u4-linux-i586.tar.gz/usr/lib/jvm/

$ cd/usr/lib/jvm/
$ sudo tar-zxvf jdk-7u4-linux-i586.tar.gz
$ rm./jdk-7u4-linux-i586.tar.gz

3. Configuration

$ sudo gedit/etc/environment

Modify path in environment, append JDK path, add classpath and Java_home as follows:
Path= "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/jdk1.7.0_04/bin"
Classpath= "/usr/lib/jvm/jdk1.7.0_04/lib"
Java_home= "/usr/lib/jvm/jdk1.7.0_04"

And then we're going to tell the system that we're using Sun's JDK, not OPENJDK:

$ sudo update-alternatives--install/usr/bin/java Java/usr/lib/jvm/jdk1.7.0_04/bin/java 300
$ sudo update-alternatives--install/usr/bin/javac Javac/usr/lib/jvm/jdk1.7.0_04/bin/javac 300
$ sudo update-alternatives--config java
There are 2 candidates that can be used to replace Java (providing/usr/bin/java).
Select Path Priority state
------------------------------------------------------------
* 0/usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 Auto mode
1/usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 Manual Mode
2/usr/lib/jvm/jdk1.7.0_04/bin/java 300 Manual Mode
To maintain the current value [*] press ENTER, or type the number of your choice: 2
As shown above, this will set up the Java to be used.
