Installing Old Version of Java

[Wyphy]

I'm trying to install an old version of Java because I have a program that doesn't run correctly on new ones; no idea why.

I'm pretty much a newb, so specific directions or links are appreciated.
Using Jaunty, trying to install Java JRE 6.0 (jre-6-linux-amd64.bin, DL directly from Sun's site)
I uninstalled the current version of JRE.

I did some searches and found:
http://ubuntuforums.org/showthread.php?t=211104
which has a pointer to:
http://www.debian-administration.org/articles/142

I followed the directions of the second link but when I run the make-jpkg and I get this message:

Creating temporary directory: /tmp/make-jpkg.TZZyvVUWuB

No matching plugin was found.

Thanks.

Installing of old version of Java 6 is a bad idea because:
-it is probably not going to solve your problem
-it will make your system vulnerable

You should rather install the newest version of Java 5.


sudo apt-get install sun-java5-jre
