I download source file from Oracle's website and installed manually from scratch... It is working well now ... The solution I used is here

The instructions given are as follows and should be updated for the current version:

Download Java SE 7 JDK for Linux x86 archive. At the time of writing,
the file I'm using is jdk-7u21-linux-i586.tar.gz, but the filename
will change as updates are released. Apparently there is no longer a
jvm folder, so create one.

sudo mkdir /usr/lib/jvm

Move the archive to the jvm folder

sudo mv jdk-7u21-linux-i586.tar.gz /usr/lib/jvm/

Change to the jvm folder and extract the JDK from the archive

cd /usr/lib/jvm

sudo tar zxvf jdk-7u21-linux-i586.tar.gz

Everything will be extracted to a new jdk1.7.0_21 folder and you can
delete the archive file now. Make symbolic links to the new java
binary.

sudo ln -s -b /usr/lib/jvm/jdk1.7.0_21/jre/bin/java /etc/alternatives/java

sudo ln -s -b /usr/lib/jvm/jdk1.7.0_21/jre/bin/java /usr/bin/java

Double-check the version

java -version
