JAVA_HOME and PATH environment variable not working in UBUNTU

I have downloaded jdk-7u9-linux-i586.rpm from oracle. Then I installed it in my Ubuntu 12.04 LTS. Then I set the environment path as : 

 export JAVA_HOME=/usr/java/<the jdk directory I cant recall now>
 export PATH={$PATH}:{$JAVA_HOME}/bin

Then I checked by echo $PATH and echo $JAVA_HOME. Now it is showing correct paths.

BUT THE PROBLEM IS : IF I TRY java IN THE CONSOLE IT IS SHOWING UNRECOGNIZED COMMAND ERROR.

Please help me.

Finally I got it.
It was all my mistake. I have set the PATH variable in the /etc/environment file and it was set wrongly. I set it upto jdk folder and not /bin after that.

After changing it to bin, I logged out and logged in again.
Now it is working fine.

Sorry guys for wasting your time and efforts.

If you simply call export in a shell, you will set the variables exactly for this one environment. If you want those variables to be there for all shell environments, add them to your ~/.bashrc or your ~/.profile files.

EDIT: I think, using a RedHat-specific packages (.rpm) on Ubuntu may be a cause of your issue - this is a rather wild guess though. You could either remove your current installation and try a different package, or better yet, install java using your regular packgage manager:

sudo add-apt-repository ppa:webupd8team/java 
apt-get update 
sudo apt-get install oracle-java7-installer

You changed your PATH, but did you re-source and refresh your PATH cache ? (see here for more details, and check section 3)

e.g.

$ vi ~/.profile
$ . ~/.profile
$ echo $PATH # is this right ?

and a possible hash

$ hash
