Newbie LimeWire and Java Installation

bdika · 09-24-2003, 07:45 PM

I have installed the latest Java Runtime on RedHat 9 but when I type in the shell:

java -version

the response I get is:

bash: java: command not found

When I type in:

which java

the response I get is:

/usr/bin/which: no java in (/usr/kerberos/sbin:/usr/java/j2rel.4.2_01/bin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/dad/bin)

Is there something wrong with my installation?

Any help would be much appreciated.

Regards,

Add

usr/java/j2rel.4.2_01/bin

to your path

/etc/profile

PATH=$PATH:usr/java/j2rel.4.2_01/bin

Add

usr/java/j2rel.4.2_01/bin

to your path

/etc/profile

PATH=$PATH:/usr/java/j2rel.4.2_01/bin

Thanks Looking_Lost.

But I don't think that I have the required directory on my system. I have already tried adjusting the path statement after reading posts at the LimeWire website. These posts gave me the same advice that you are proposing.

However when I try to change to the required directory I get the following:

[root@localhost java]# cd /usr/java/j2rel.4.2_01/bin
bash: cd: /usr/java/j2rel.4.2_01/bin: No such file or directory
[root@localhost java]#

Does this mean that I don't have Java on my computer? When I downloaded and installed the latest version from Sun's website there did not appear to be any problems.

I am using the latest version of Red Hat 9 (updated via downloads on the internet).

Thanks again Looking_Lost.

If you have any other ideas I would be glad to try them.

I ended up using the path /usr/local/java/, and it detected one of my JRE's I installed, I think.... I had 1.4.1.3 and 1.4.1.5 on my box at one time(before my reformatting), but I eventually got it to work with Sun's JRESDK. Then again, I am also on Slackware, which is different from RedHat....

Not that there's anything wrong with either of them, but that they don't operate identically.

'Tis strange

The way I normally find where things are

updatedb

then

locate java

or

find java | more

if nothing comes up for that then something has more than likely gone wrong with your install

Thanks

I tried

locate java

There are a lot of java files on my computer so the installation worked. But there appears to be something wrong.

There is a 24 KB executable file called java in the directory :

/usr/java/j2sdk1.4.2_01/bin

When I click on it in the Konqueror window a dialog box comes up which says:

"Couldn't find the program java."

Does that mean there is a missing component or file?

I have now installed both the run time and the SDK.

Another way I tried to determine if java was installed was:

[root@localhost bin]# cd /usr/java/j2sdk1.4.2_01/bin
[root@localhost bin]# java -version
bash: java: command not found
[root@localhost bin]#

As you can see, I haven't had any luck.

Any ideas would be greatly appreciated.

Thanks r_jensen11

But I don't have a java directory in my /usr/local/ directory.

Any other ideas?

Please see my other post to get an idea of the responses I am getting from my system.

have you tried using your path /usr/java? Check and see if that works. Does anything else you have use java?

Looking_Lost · 09-27-2003, 11:02 AM

If you've got a directory

/usr/java/j2sdk1.4.2_01/bin

You've downloaded the full development kit

Clicking on java file alone isn't the way it's supposed to be used
if you go to a terminal and cd to that directory and then type in

./java

You should get output like this

Code:


Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-options] -jar jarfile [args...]
           (to execute a jar file)

where options include:
    -client       to select the "client" VM
    -server       to select the "server" VM
    -hotspot      is a synonym for the "client" VM  [deprecated]
                  The default VM is client.

    -cp <class search path of directories and zip/jar files>
    -classpath <class search path of directories and zip/jar files>
                  A : separated list of directories, JAR archives,

and so on

It should really be used to invoke a program

i.e

java my_java_program

All I can suggest now is in /etc/profile to add

PATH=/usr/java/j2sdk1.4.2_01/bin:$PATH

JAVA_HOME=/usr/java/j2sdk1.4.2_01

export JAVA_HOME

logout and back in again

Thanks a million. I now have LimeWire up and running thanks to you. At the LimeWire forum there are very detailed instructions for the installation of java. I followed these instructions precisely and they contained advice very similar to yours but what you pointed out to me that they didn't was that I should log out after adding path information to /etc/profile and then log back in.

Again, many thanks.

And thank you r_jensen11. I appreciate anyone who takes the time to read and respond to the posts of us newbies. Many thanks.
