HI GUYS,

i installed jdk 5.0 in my home directory, but the compiler & other utilities like javac and java are not working...

i installed it from a .bin(self extracting file).

how do you know that's not working!? Is there any error messages?!

It doesn't matter where it was installed. We've just to add <JDK>/bin to environtment variable PATH.

Hi there!

I've some tips:

1 - Do not install anything at your home directory. Choose a more appropriated place as /usr/local or /usr/local/share or /opt/. Doing that, Java SDK would be available to every user on your machine, otherwise you will need to install java again for every other user, thus wasting resources.

2 - Java SDK installation instructions is very well documented at Sun's homepage. If you follow it step by step, you will get it to work:

http://java.sun.com/j2se/1.5.0/install-linux.html

3 - Exporting your PATH would work (it's similar to Windows Environment Variables), it's done by adding these lines to your /etc/profile or ~/.bashrc

PATH="$PATH:/usr/local/java/j2sdk<version>/bin"
export PATH


Note: the above line is an example. Use your Java SDK directory instead.

4 - java and javac are both located at the folder where JSDK was decompressed. I believe yours should be something like /usr/local/java/jdk1.5.0/bin/

You could simply create a link for java and javac to your /usr/bin (I do that, instead of using PATH variables). eg:

ln -s /usr/local/java/jdk1.5.0/bin/java /usr/bin/java
ln -s /usr/local/java/jdk1.5.0/bin/javac /usr/bin/javac

Many would not recommend this method, because a few important tools such as jar and appletviewer are left out (unless you link them too). You can test Java anytime now by typing "java -version" at the terminal.

Good luck!

I'm glad I could help . Oh and thanks for your reply too. I wish more new members were like you and replied either telling if what was suggested worked or not, so the thread can be used by other members as well.

Best Regards!
