Others have given specific instructions etc.; here are links to a wealth
of help & information regarding Ubuntu that you should bookmark and read
through. The help.ubuntu.com site uses a custom google search engine, so
you can enter searches just as you would in google:

/usr/share/jedit/modes is a system folder.

You'll need 'superuser' permissions to write the files there. So the
simplest way via jedit is to use:

$ gksudo jedit <filename>
or
$ gksudo jedit <path-to-file><filename>

That will open the file in superuser mode (gksudo - or gksu is used
because jedit is a graphical editor), and from there you can save the
file to /user/share/jedit/modes.

But I reckon it's much wiser to follow Tim's advise regarding
/usr/share/jedit/modes...

You might also find gedit of use:

it is installed by default on your system.
