Dear All,
I have installed j2sdk-1_4_0-linux-i386-rpm.bin succussfully.
it installed /usr/java/j2sdk1.4.0 folder with all the files..

then i opend .bashrc file from /home/guest folder
I added following way

#JAVA
JAVA_HOME=/usr/java/j2sdk1.4.0
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
export PATH

then i saved and run the file like this

source ~/.bashrc

Eventhough I am not able to run any java command

pls give me suggestion..

try
> which javac
and see if it returns someting
if it doensn't, some configuration is incorrect..

gl

Post the output of

[bash]# which java

[bash]# echo $PATH

Are you using KDE/konsole and auto login to X windows?

Yuo have Java SDK (Software Development Kit) . Its used to create Java aplications . You need to get JRE (Java Runtime Environment) to use java in your browser or anything like that if thats what you mean.

Actually the SDK comes with a JRE.

Try a different Compiler a.k.a. Jikes from IBM, I remember reading something about rh7.0 and suns compiler not getting along. Besides jikes is faster anyway.

I am using KDE/konsole and auto login to X windows. After I install jre 1.3 to /usr/local folder, ln java to /bin/java, and on prompt type "java" or "java -version", the system just hangs there.
What is going on here?
While I typed in "whereis java", it showed "/bin/java"

Your advice is greatly appreciated..

I think it sounds like you copied your virtual machine from your JAVA_HOME/bin to /bin/java. This will not work cause now the VM can't see the rest of your java library.

So if you want to write java programs, what you want to do is install the Java SDK not the JRE (I think they are up to 1.4.1 now). First I would create the folder /usr/local/java. That is where I keep all my sucessive SDK's. Then I would install my Java SDK into this folder.

when you are done it should look something like this:
/usr/local/java/j2SDK1.4.1/

next you want to make symbolic links to the Virtual machine(AKA java) and also the compiler (AKA javac), put these links in your /usr/bin or just your /bin directory.

e.g.
ln -s /usr/local/java/j2SDK1.4.1/bin/java java
ln -s /usr/local/java/j2SDK1.4.1/bin/javac javac

This way when you want to upgrade to the next SDK you install to /usr/local/java and just change your symbolic links.

Hope this helps,

Hi cludwin:
Thanks for your prompt response.
I only need to install VM to run the java program. Our product needs only JRE 1.3.0. It seems to me that this version is not compatible with Linux KDE. I say this because it works with JRE 1.3.1_04 by going thru the same procedure.
I just want to confirm the fact that JRE 1.3.0 is not compatible with KDE.
Only if anyone knows how to tweak and make JRE 1.3.0 work in KDE please let me know. Greatly appreciate.
