Smile Java on linux how to


I am looking for java for linux. I am using redhat 9. I went to the java.sun website to download but i was a little confused. Does anybody know which version to download and how to install it? Thanx! Another question: What is the difference between .rpm and scr.rpm files? How do .src.rpm get installed? As you can see I am new one!..

Just get rpm package as src.rpms are source code for compiling and building the package.


I do believe the latest edition that you can use is 1.4.2_02

Go to this page then to the section titled Download J2SE v 1.4.2_02 and download the RPM self-extracting file and then follow these instructions. That should do it

(Ripped from my post on knoppix.net a couple of months ago)

Quote:
Sun does not use an open license for Java so it is not included with the official Debian archives, so you can't apt-get install with a stock /etc/sources.list file.

However, the Blackdown project (blackdown.org) provides Java packages for Debian (and many others). These are not very up to date (usually) so I just download the Java SDK (not the JRE!) from Sun and install it.

Here's how you do it:

1. Download the "Linux self-extracting file" package from http://java.sun.com/j2se/1.4.2/download.html

2. Create a directory for Java related stuff under /usr/local:
$ cd /usr/local
$ su (enter password for root, note that the prompt changes when you're root)
# mkdir java
# cd java

3. Then you need to run the file. With this file you can do it like this:
# sh j2sdk-1_4_2_01-linux-i586.bin
....or like this:
# chmod +x j2sdk-1_4_2_01-linux-i586.bin (this makes the file executable)
# /home/hw/downloads/j2sdk-1_4_2_01-linux-i586.bin (execute it - run this from the /usr/local/java directory)

4. Now it's installed. Still, the java and javac commands won't work from the command line because the /bin subdirectory from the SDK isn't in the path. We need to add them somehow. There are many different ways of doing this but this is how I usually do it:
Edit /etc/profile (as root) with your favourite text editor. There should be a line that specifies directories that contain executables and should be added to the PATH environment variable. Something like this:
PATH="/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games"
The directories are separated by colons (":"). Add a colon at the end of the line (but before the closing quote) and add the Java bin directory. If you followed my outline above it should be /usr/local/java/j2sdk1.4.2/bin/.
Now the line looks like this:
PATH="/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games:/usr/local/java/j2sdk/bin"
Save the file!

Either log out and log in again or do a "source /etc/profile" to let the changes take effect. Type "javac" at the shell prompt and you should see the exact same thing as you see on Windows!
