I am facing a problem while trying to install Java 7 on Ubuntu.

The following are the steps that I performed for installing:

I installed the setup file from the link given below:

wget http://download.oracle.com/otn-pub/java/jdk/7u1-b08/jdk-7u1-linux-x64.tar.gz

1. I have a file: jdk-7u1-linux-x64.tar.gz

2. I Untared it:

   tar -xvf jdk-7u1-linux-x64.tar.gz

3. sudo mv ./jdk1.7.0_01 /usr/lib/jvm/jdk1.7.0_01

4. sudo update-alternatives –config java Here it gave me the following output:

   There is only one alternative in link group java: /usr/lib/jvm/java-6-sun/jre/bin/java Nothing to configure.

5. sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_01/jre/bin/java 1(I entered 1 here.)

6. sudo update-alternatives --config java

7. java -version.

It showed the following output

java version "1.6.0_26"

Java(TM) SE Runtime Environment (build 1.6.0_26-b03)

Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

I am not sure if jdk1.7.0 is installed as its showing the version as 1.6.0_26.
