Having some problem with redhat installation

I have needed to change my linux version to redhat.
I have downloaded the j2se called
j2sdk-1_4_1-beta-linux-i586-rpm.bin
At command prompt type
$./j2sdk-1_4_1-beta-linux-i586-rpm.bin
After agreeing to the license it opened a directory:
(1) j2sdk1.4.1
iside this directory 1 hidden file called
.systemPrefs
(2) j2sdk-1_4_1-beta-linux-i586-rpm
At command prompt typed:
$ rpm -iv j2sdk-1_4_1-beta-linux-i586-rpm
Preparing packages for installation ...
j2sdk-1.4.1-beta
But there is no folder called j2sdk-1.4.1-beta
Nor is there anything in the folder j2sdk1.4.1
What can I do?
Please help

An RPM file will not unpack like a tar (which seems to be what you are expecting). You can see where files were installed by using the following command:
rpm -ql jdk
I believe Red Hat installs the jdk in /usr/java

Thank you vert much James O'Dell
I am very greatful. Yes indeed you are correct. Please note I have read the j2se documentation and followed there installation instruction for linux at this url: http://java.sun.com/j2se/1.4/install-linux.html. Unless one has used linux redhat before one could not know where it installs these programs???
I believe I can follow instruction but Sun are sometimes inconsiderate for some mere mortal users? If they provided this then I would not need to be so concerned.
Another Question:
I just want to make sure everything I will be doing is correct. If I wanted to execute the java and javac commands from any where, would I edit the .bash_profile file? My OS is Linux Redhat 7.2
If so I have three of these files located at
(1) /var/lib/nfs/.bash_profile
(2) /etc/skel/.bash_profile
(3) /home/sid/.bash_profile
Which one should I edit?
Here is my bash_profile located at /home/sid/.bash_profile:
#.bash_profile
# Get the aliases and functios
if [ -f ~/bashrc ]; then
. ~/.bashrc
fi
# user specific aliases and functions and startup programs
PATH=$PATH:$HOME/bin
export PATH
unset Username
-------------------------------------------------
I believe I have to set the environment path???
export PATH=$PATH:/usr/java/j2sdk1.4.1/bin
If so where in the above file should I type this?

Here's a real-world .bash_profile I use. The only unusual thing is the stuff relating to the EJBWizard. The JOnAS stuff is for my EJB server of choice (http://www.objectweb.org/jonas).

Sid,
You are correct, you want to edit /home/sid/.bash_profile
add your new "export PATH=" statement to the end of the file.
The /etc/skel/.bash_profile is a default file that will be put into a new user's home directory. For example, when you added "sid" as a user the system copied /etc/skel/.bash_profile to /home/sid.

I know it can seem difficult to find all of the information you need in order to use a product like the j2sdk on RedHat or any flavor of Linux. However, it's not really Sun's responsibility to give that level of operating system support(except for Solaris of course). A lot of frustration can be avoided by spending some time learning the fundamentals of the OS.
Keep at it, and good luck.
Jim
