basic ide and Java installation

[Calidus]

Hello all,

I am new to linux and i am using Fedora 13 inside virtual box. I am going to be writing a C Shell for my operating system class. I plan on using Eclipse as my ide because i am familiar with it.

Now to my problem to install eclipse i need to have the Java JRE installed in /urs/java. I downloaded the .bin file. I then try to mv file.bin /srs/java but the terminal says i don't have permission. So i tryed to cd function and got the same problem. So i went into the system->users and groups and checked every box for my user. I assumed this would give me 100% admin rights(for better or worse). I went back and tried and i got the same thing and got the same message.

I am stuck.

After i get unstuck(with alittle help from you guys) i will then ./file.bin to run the self extract and continue on my merry into learning abotu linux and operating systems.

thanks,

Calidus

(P.S. anyone know of an easy way to run fedora and virtual box in full screen)

Hi and welcome to the forums. Are you doing this as super user?

su -

Assuming you are, you may have to give yourself permission to execute the file:

chmod a+x file.bin

Then:

sh file.bin

[Calidus]

First thank you for responding

How would i know if i am a super user? EDIT: I CAN"T READ.

I have tried the

chmod a+x file.bin

command, followed by the

mv file.bin /urs/java

and it still returns the message Permission denied

I have also tryed to create a folder using mkdir and i get the message Permission denied.

Ok that kinda helped but now i don't know how to move the file.bin from the users home folder(i don't know the technical term sorry) to the root home folder to then be able to move it to the /urs/java folder.

Is their a command that will let me move stuff like a super users in the GUI?

If you don't know if you are su you probably aren't. To become user with root privileges, do from the command line:

su -

Enter your root password when is asks and press enter. Then the little '$' should become a '#." If you see the '#' then you are su.

There are several methods for installing java on Fedora 13. a few of them are listed here. Sounds like you downloaded the Sun version so go with Sun Java (Method 1) if that is the case.

I have found an error in these directions in method 1 linked above(can't post links yet)

 ln -s  /opt/jre1.6.0_20_i586/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/libnpjp2.so

the file is jre1.6.0.21 not jre1.6.0_20_i586 when i look in my file system. I have tried using both but i still get a message saying:

creating symbolic link '/usr/lib/mozilla/plugins/libnpjp2.so' : no such file or directory found

the when i look in the file system i can't find /usr/lib/mozilla/plugins/libnpjp2.so so i guess i am missing something. I followed all the previous step correctly and with basically no problems.

You need to create the directory 'plugins.'

mkdir /usr/lib/mozilla/plugins

If you are using Firefox, you can do the same thing...

mkdir /usr/lib/firefox/plugins

 ln -s  /opt/jre1.6.0_21_i586/lib/i386/libnpjp2.so /usr/lib/firefox/plugins/libnpjp2.so

[Calidus]

the plugins directory already exist

(can't post complete links yet)

[Dapper Dan]

So when you look into this directory...

cd /usr/lib/mozilla/plugins
*enter*
ls
*enter*

You don't see libnpjp2.so?
Did you try it with Firefox?
Really, all this is just to get Java going for when you access java on the Internet. For your purposes, Java might be working as you need it to for your programming.
