RH8 and Java
 

ok...here's the deal...I just installed RH8....updated all my packages and Kernel....and am now trying to set up my JAVA.

Well.....whether I d/l 1.3.1 or 1.4.1 I get the same message every time I try to install....

After I type YES to my User Agreement....I get some "trail: bash" error message. What the hell is going on? Tells me the file is corrupted and not to install. But this happens with both versions???

Do I need the SDK?

I can't answer your first question, but I can answer the second. If you only want to run Java programs/applets, then you only need the JRE (which, I take it, is what you have now). If you want to write Java programs, or run Java programs from source, you need the SDK.

The only suggestion I can make as to resolving your problem is to try another version. If you have the one from Sun and it's not working, try the IBM version. They're both very capable. But I'm sure a more knowledgeable person will be able to suggest an actual cause to your problem.

1)

* Create a download directory:
*

mkdir $HOME/archive

2)

* Download J2SE 1.4.1 sdk RPM to your archive directory. Get the SDK here.
* The file is called: j2sdk-1_4_1_01-linux-i586-rpm.bin
* This script is not executable, therefore type:
*

chmod a+x j2sdk-1_4_1_01-linux-i586-rpm.bin

*

./j2sdk-1_4_1_01-linux-i586-rpm.bin

* Than agree to the licensing terms.

3)

* Note that your archive directory now contains a new file called: j2sdk-1_4_1_01-fcs-linux-i586.rpm
* Install the SDK. Type: su (and enter super user password).
*

rpm -ivh j2sdk-1_4_1_01-fcs-linux-i586.rpm

* The SDK is now installed however there are still a few configuration tasks.
* This is where most people have trouble.

4)

* Linking the plugin to Mozilla and Galeon (Galeon uses Mozilla plugins).
* We should still be in super user mode. If not than become super user again: su (password).
*

ln -s /usr/java/j2sdk1.4.1_01/jre/plugin/i386/ns610/libjavaplugin_oji.so /usr/lib/mozilla-1.1/plugins/

* Now your browers (Mozilla and Galeon) will display Java2 1.4.1 websites.
* Exit as super user. Type: exit

5)

* Configuring the executable PATH.
* In regular user mode.
*

emacs $HOME/.bash_profile

* At the very bottom of the file add the line:
*

export PATH=/usr/java/j2sdk1.4.1_01/bin:$PATH

* Exit emacs by holding down Ctrl and pressing x than s than x than c.
*

Ctrl - x - s - x - c

* Now log out and log back in, so that the settings to take effect.

6)

* Test the configuration of the executable PATH. Simply type:
*

javac

* You should see a list of the java compiler command switches.
* Find a tutorial or book and write some Java2 programs.
* If you have problems you can mail

* Note: If you have a backup file (ls -al $HOME) called .bash_profile~ in addition
* to your new .bash_profile (without the ~), than delete the backup (rm ./.bash_profile~)
* Than try loging back in and everything should work. For some reason the backup file
* overrides the new script.

search google for blackdown java, I believe they have an rpm that works quite well

(at any rate their deb packages work).
