I know, there are several ways of installing ORACLE jdk7 on Debian. One way is to use the ppa from the web8updteam but i've read that installing software from ppa is not recommended on Debian. (is this true, btw??)
So I decided to follow this guide to install oracle jdk. Here it's recommended to use java-package to generate a .deb package of the jdk binaries and then install it via dpkg:
$ make-jpkg jdk-7u45-linux-x64.tar.gz $ su $ dpkg -i oracle-j2sdk1.7_1.7.0+update45_amd64.deb
The problem with this approach is, that I will loose continuous updates of the jdk.
So, my question is, how do I actually update to a newer jdk? Simply download the newer jdk, remove the current installed jdk with dpkg -r and repeat the instructions above again?
