During the installation I just search the internet of guide on installing java in linux, and I took down a note for the procedure, this is only my personal reference information but if you want to follow this then you can do so.
1. goto http://java.sun.com/javase/downloads/index.jsp and 
download JDK 6

2. on the download page select Linux OS, just skip the create 
account window and click the download link for  jdk-6u18-linux-i586.bin

3. upload the jdk-6u18-linux-i586.bin to your linux server

4. create a folder for the java :   mkdir java

5. move the file to java folder :   mv jdk-6u18-linux-i586.bin java/

6. set he owner to root :  chmod +x  jdk-6u18-linux-i586.bin

7. execute the installer: ./jdk-6u18-linux-i586.bin  , press space bar 
to continue with more prompt and enter yes for agree

8. to test if java is installed just enter javac , if error command 
not found this means your java is not yet register in global path 
or environment

9. to set the path to Java enter this :  
export PATH=$PATH:/root/java/jdk1.6.0_18/bin

10 to reload the environment enter this: source /etc/profile
To set the path permanently you can do the step below

change to your home directory (ie: /home/myname) and type....

vi .bash_profile (note the fullstop before \'bash\'. This \'.\' makes it a hidden file)
then arrow down until you find the line that looks similar to this.....


type i to enter \'insert\' mode,
(remember to use the \':\' between directory names).
Press the escape key to exit \'insert\' mode,
type :w to write the file
type :q to quit the vi editor

Ok hopefully this is useful to you, on my case I use VPS Linux RedHat and I don\'t get any error during installation, I just posted it here for my own reference only
