How to paste files in jre folder?

Question

I am trying to copy .jar and .so files into jre folder. I tried to do it like I do it in windows but it is not working, maybe the permission problem. So how can I do it? using terminal or is there any other way? File which i want to copy is RXTXcomm.jar path is /home/adi and I want to paste it in jre path is /usr/lib/jvm/java-7-oracle/jre/lib/ext

I am very new to Linux, I got it only couple of hours ago so please bear with me!

Answer 1

You can use:

alt+f2 gksu cp /home/adi/RXTXcomm.jar /usr/lib/jvm/java-7-oracle/jre/lib/ext.

Or you can run it in the terminal:

sudo cp /home/adi/RXTXcomm.jar /usr/lib/jvm/java-7-oracle/jre/lib/ext.

Answer 2

From command line (windows key to open dash, search for Terminal)

If the file is in /home/adi this will work:

cd /home/adi/
sudo RXTXcomm.jar /usr/lib/jvm/java-7-oracle/jre/lib/ext/

You need sudo if the destination is not owned by your user.
