Unable to access java files after downloading Oracle Java 7

Hi Team,  

   Just a quick question on how to have my Centos 6.4 have its java version repointed from the basic OpenJDK to the Oracle version.

After installing  jdk 7  ( I got the jdk-7u55-linux-i586.rpm.) from the oracle web site, I did this...

JAVA_HOME=/usr/java/jdk1.7.0_45
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME
export PATH

--------------then updated the symbolic links ------------------

update-alternatives --install "/usr/bin/java" "java" "/usr/java/jdk1.7.0_55/bin/java" 1

update-alternatives --install "/usr/bin/java" "java" "/usr/java/jdk1.7.0_45/bin/java" 1
update-alternatives --set java /usr/java/jdk1.7.0_45/bin/java

update-alternatives --install "/usr/bin/javac" "javac" "/usr/java/jdk1.7.0_45/bin/javac" 1
update-alternatives --set javac /usr/java/jdk1.7.0_45/bin/javac



[root@neo4j au123456]# echo $PATH
/usr/lib/qt-3.3/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/au123456/bin:/usr/java/jdk1.7.0_45/bin
[root@neo4j au123456]# java -version
bash: java: command not found

---------------------------  I looked for all references of java on my file system --------------
[root@neo4j au123456]# find / -name java

Select allOpen in new window

* To make java -version work I had to do this:

[root@neo4j au123456]# cd /usr/java/jdk1.7.0_55/bin
[root@neo4j bin]# pwd
/usr/java/jdk1.7.0_55/bin
[root@neo4j bin]# java -version
bash: java: command not found


[root@neo4j bin]# ./java -version
java version "1.7.0_55"
Java(TM) SE Runtime Environment (build 1.7.0_55-b13)
Java HotSpot(TM) Client VM (build 24.55-b03, mixed mode, sharing)
[root@neo4j bin]# 

Select allOpen in new window

It's like the java executables are not in the path.  I think I am missing something simple, just can't quite figure out what it is.

Thanks in advance for the help.
