Java Installation--help

Hello, I am using Mandriva 2006 and I just download java from: Here

I need to java working as soon as possible. I have it working but I have to go the bin directory then do the command

Code:

---

./java (file)

---

I need to know how to get the classpath working so that I can run the java from my home folder or other folders. I really appreciate the help. Thank you.

If you're using KDE then;
right click on the desktop
create new --> link to application
Name it as Java (or whatever)
Go to the application tab
enter the location of the application in command (something like /bin/java most likely)
click OK and you should now have a desktop icon

right clicking on Kmenu and selecting menu editor will allow you to add a link from the menu in a similar manner.

I tried that but here's what happened in the command line:

Code:

---

[root@localhost name]# ls
Desktop/    Download/        java*  Pictures/  Video/
Documents/  HelloWorld.java  Music/  tmp/
[root@localhost name]# ./java
./java: line 1: [Desktop: command not found
./java: line 17: X-DCOP-ServiceType=: command not found
./java: line 18: X-KDE-SubstituteUID=false: command not found
./java: line 19: X-KDE-Username=: command not found
[root@localhost name]#

---

Am I putting the correct properties in for the application tab? Thanks again.

Where EXACTLY is java located on your system?

From your first post I take entering either of following in the command line will run java

Code:

---

/bin/java

---

or

Code:

---

cd /bin/
./java

---

Is this correct?
If not what do you enter to run it?

If this is correct then enter /bin/java in the command area on the application tab of the link setup window.

Otherwise enter the full pathname of the application.

It should look something like this;
http://i23.photobucket.com/albums/b3.../linksetup.gif

It is located in

Code:

---

/usr/java/jdk1.5.0_06/bin

---

This is where the java and other commands are located.
So what exactly would I put in? Thanks for all the help

I tried what you said but I still get the same error. Can I try changing classpath or something? I really need to get this working. Thanks so much.

The easiest thing I've found is to add the path to Java's bin directory to my ~/.bashrc.
For example, here's two lines I appended to the end of my .bashrc:

Code:

---

# Path to java
export PATH=/usr/local/apps/jdk1.5.0_06/bin:$PATH

---

With this, my shell knows to keep that path in mind, and I can run java apps from anywhere.

I just copied the java command to /usr/sbin and the java command works except it comes up with an error:

Code:

---

[root@localhost name]#java
Error: could not find libjava.so
Error: could not find java 2 Runtime Environment

---

I tried the command when I was in the bin directory and it worked. I'm guessing it is not working because I am not running it from the bin directory.

In the bin directory, the error still comes up but it doesn't if I run ./java instead of just java. If I run ./java from a different directory it says file not found and if I just run java then the error comes up. Any Ideas? Thanks.

Have you tried adding the Java executable to your path?

PATH=$PATH:/path/to/java/binary

;)

Also - in your /etc directory there's a file called environment. As root you could add this line to environment:

export JAVA_HOME=/usr/java/

You might need to log out and in again. Then type env on the command line to see if it got added. I tried this the other week and it worked for me. It kind of assumes a similar java installation to mine, but I think we have the same version.
