I am still quite a newbie when it comes to Linux, and have a long way to go yet before I could be considered an expert. But slowly I am getting there.

Today to help with setting up the firewall to allow email, I thought it was time I finally got around to installing Java on this PC, and because CISCO SDM express requires an old version this means setting up multiply versions.

Installing the first one is simple enough

$sudo apt-get install java….

(you can do an

$apt-get update

followed by

$apt-cache search java

and this will show you what versions are available for download.)

and after a bit of poking around the second one was simple enough as well, download the bin file from www.JAVA.com and extract it to a directory (this can be any where you want, although the /opt/ one seems to be a common choice) as below. If you want more instructions just click on the instruction link on the site.

$sudo sh ./java-5-4…..

Then cheat and open the java desktop control panel open up the runtime environment settings and add in you new version. (if any Linux masters wan’t to post the guru way to do this please do 🙂 )

And there you have it multiply JAVA installs.

Only one issues now though, Firefox does not support Java below version 6-10, and SDM still does not work! So its on to the next method to get SDM working on Linux.

I will get this email working soon…

Take care all.
