Java version not the one I have installed
 
I have installed Java 1.6.0
Code:
/usr/local/jdk1.6.0_24/
But I still get the old version
Code:
java -version
java version "1.4.2"
gij (GNU libgcj) version 4.1.2 20080704 (Red Hat 4.1.2-50)

I know that I need to change my bash_profile but when I try it does not solve the problem


Code:
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
PATH=$PATH:/usr/local/jdk1.6.0_24/bin/
export PATH
What am I doing wrong?

You added your new java path to the end of your path statement, but the previous JDK was already in your path, and is therefore coming up first in your search order.

First, verify your change to .bash_profile has successfully updated your path (I usually make these changes to .bashrc):

Code:
echo $PATH
If so, then go back and reverse the order of your path arguments in .bash_profile so that the new JDK comes up first. I don't see any reason for having multiple path statements, so...

Code:
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

export PATH=/usr/local/jdk1.6.0_24/bin:$PATH:$HOME/bin

A previous java will usually be a link /usr/bin/java to /etc/alternatives/java.

I don't think, the bashrc will override that.

Default install location : /usr/java/jdk1.6.0_24

And the default way of setting up java : 1) su
2)
/usr/sbin/alternatives --install /usr/bin/java java /usr/java/jdk1.6.0_24/bin/java 2

3) /usr/sbin/alternatives --config java
.... Then select version : sun.
....

That fixed it - I mean changing the profile fixed
Code:
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

export PATH=/usr/local/jdk1.6.0_24/bin:$PATH:$HOME/bin
